3.8. Additional requirements for ACOUSTIC INSULATION This Specification includes the technical requirements for the design and application of acoustic insulation to piping and equipment, in combination with or without thermal Insulation.

This Specification describes the set-up and application of sound pressure levels or required or achievable noise reductions. Dealing with acoustic problems is the work of an acoustic specialist, who will design and specify what items, shall be insulated, in what manner and to what classification.

This Specification is related to ISO 15665, in terms of classification or acoustic insulation for piping, valves and flanges.

These requirements substitute the requirements for specification “P” for all new equipment and piping that shall be provided acoustical insulation.

3.8.1. Classification of acoustic insulation

Acoustic insulation is divided in 3 classes:

Class A : Lightest noise reduction, most economic

Class B : Medium noise reduction

Class C : Heavy noise reduction

The thickness of the acoustic insulation and minimum jacketing mass for the four defined classes is indicated in Table 2, unless specified otherwise.

Minimum jacketing mass

[kg/m2]

A 50 2

B 1st layer 50 2nd layer 50

5

C 1st layer 50 2nd layer 50

10

Additional requirements for each class are specified below.

3.6.1.1. Class A Flanges and valves do not need to be insulated.

3.6.1.2. Class B The porous layers shall be applied in two 50 mm layers with staggered joints.


Pipe with a diameter ≤ 80 mm (≤ 3 inch) shall have maximum insulation thickness of 50 mm.

Distance and support rings shall be avoided whenever possible.

All flanges and valves shall be insulated to the same class as the pipe, except for valves and flanges in hazardous service.

Pipe supports shall be insulated up to the concrete or steel base.

3.6.1.3. Class C The minimum jacketing mass shall be obtained by a combination of steel jacketing and mass loaded thermoplastic sheet. Mass loaded thermoplastic sheet material is specified in paragraph 3.3.2.2.

Pipe supports, including guides, but not including anchors, shall be mounted on a vibration-isolating pad.

In addition all requirements of Class B apply.

3.8.2. Material requirements

The material requirements are equivalent with the material requirements for hot insulation with the following exceptions:

► Mass of jacketing

► Use of mass loaded thermoplastic sheet

► Minimum air flow resistance of insulation material of 25,000 - 75,000 Ns/m4

► No rigid contact allowed between pipe and jacketing (use of anti-vibration seals and special support of jacketing)

► The drawings of ISO 15665 apply

3.8.2.1 Porous layer

The porous layer shall be mineral wool in accordance the requirements of thermal insulation.

The air flow resistance of the porous layer specified above is normally obtained by materials with a density range of 65 - 125 kg/m3. The range may be extended to 50 kg/m3 for Class A insulation.

3.8.2.2 Jacketing

Minimum jacketing mass per unit area shall be according Table 2 for the acoustic insulation class considered.

Jacketing material shall be aluminium or stainless steel as per hot insulation specification combined with mass-loaded thermoplastic sheet as required.

Approved thermoplastic sheet materials are:

a) IDIKELL self-adhesive, 1.5 mm thickness, mass 3 kg/m² or 2.5 mm thickness, mass 5 kg/m²

b) TERODEM 5500, 2.6 mm thickness, mass 5 kg/m²


3.8.2.3 Anti-vibration seals

At locations where metal-to-metal contact occurs, anti-vibration seals shall be applied. Anti-vibration seals shall have a minimum thickness of 3 mm and a minimum width of 50 mm.

The edges of the jacketing or end cap shall be folded where they rest on the anti-vibration seal. The anti-vibration seals shall be suitable and fully resistant to the specified operating temperature

The following materials are suitable for use in anti-vibration seals:

(a) Synthetic rubber

(b) Natural rubber

(c) Non-flammable felt

Where these materials are not compatible with the operating temperature, the seal shall be made from compressed porous-layer material. Alternatively a clearance of about 10 mm may be left where weather protection of the pipe is not a consideration. Note that, in many cases, anti-vibration seals may also be required to act as a watertight seal and the material shall be suitable for this.

3.8.3. Support of jacketing

Where semi-rigid sections are used on horizontal pipe it will normally not be necessary to support the jacketing; but where blankets are used it may be necessary to support the jacketing through the porous layer. Semi-rigid sections, used at intervals, may be suitable for this provided they are compatible with the operating temperature and the chemical environment.

Rigid spacers, as used in distance rings for thermal insulation, shall not be used in acoustic insulation. Where it is necessary to use spacers, they shall contain a resilient element to reduce the transmission of vibrations from the pipe. Where necessary the resilient element shall have a built-in mechanical stop in the direction normal to the pipe axis in order to limit its mechanical deflection.

With vertical pipes, any supports which carry the weight of the jacketing, shall contain resilient elements to reduce the transmission of vibrations from the pipe. Where necessary, these resilient elements shall contain mechanical stops to limit excess movement.

Resilient elements shall not be loaded to such an extent that their operational range of deflections is exceeded.

Acceptable examples of additional jacketing support other than the use of semi rigid sections are included in ISO 15665.

The required method for supporting the jacketing shall be agreed between the parties responsible for the mechanical and acoustic design.

Additional supports shall not be welded without written approval from Company’s Representative.

3.8.4. Installation

3.8.4.1 General

The requirements of any relevant specification for thermal insulation shall apply, except where excluded or superseded by this specification.


An essential feature of acoustic insulation is that the jacketing must not be in direct or indirect metal-to-metal contact with the pipe, or the equipment. Any such contact will allow a transmission of vibrations to the jacketing which will reduce or nullify the noise reduction of the insulation; it may even enhance the noise radiation due to the greater surface area of the jacketing. It is also important that there shall be no gaps in the insulation. Joints in the porous layer shall therefore be staggered and the jacketing shall overlap at all joints.

If a multiple layer system is used, the joints of insulating materials of two consecutive layers shall be staggered, generally single layer of insulation shall not exceed 75 mm.

3.8.4.2 Extent of insulation

The length of pipe to be insulated and the class of insulation shall be specified by Company’s Representative Noise Control Engineer responsible for the acoustic design.

Insulation of pipe supports, flanges and valves shall be in accordance with the requirements of the Class (see paragraph 3.3.1.). Otherwise, the specified length of pipe shall be insulated to cover the whole of the noise-radiating area, without gaps or voids.

3.8.4.3 End caps

At all exposed flanges the acoustic insulation shall be terminated with an end cap. This shall be located as close to the flange as possible and shall not interfere with the requirements for bolt removal. The end cap shall be isolated from the pipe by means of an anti-vibration seal.

3.8.4.4 Acoustic removable enclosures (not for class A)

The acoustic enclosure shall have an outer surface of metal sheet with a mass per unit area at least equal to that of the jacketing. The porous layer shall be similar in material to that used on the piping and shall be retained by an inner surface layer which is at least 10 mm away form the flange or valve; for example, perforated-metal sheet with an open area of not less than 30%. In general, a thickness of 100 mm will be sufficient for the porous layer of a valve enclosure.

Where acoustic enclosures are installed around flanged joints they shall be of sufficient length to overlap the end caps on the pipe jacketing by at least 100mm for Class B and 200mm for Class C.

Removable parts of acoustic enclosures heavier than 25 kg shall have lifting lugs.

3.8.4.5 Insulation of equipment (vessels, pumps, compressors)

Acoustic insulation of vessels shall comply with the above requirements for piping insulation. For pumps and compressors, acoustic enclosures shall be considered.

5. Thermal insulation design base

5.1 Function of thermal insulation

5.1.1 General

Thermal insulation is intended mainly to provide at least one of the following functions:

• heat conservation: coded HC (Heat Conservation),

• protection against cold: coded WT (Winterisation),

• protection of personnel: coded PP (Personnel Protection),

• insulation with heat tracing: coded HC (Heat Conservation).

Note:

The reader is reminded that the symbols corresponding to the types of thermal insulation shall be indicated alongside the identifiers of the lines included on the process and flow diagram (see TOTAL specification GS RM GEN 001).

All thermal insulation shall be clearly and legibly marked with the name or code of the item to which it is assigned.




Page 8/30

5.1.2 Heat conservation (HC)

The thermal insulation shall be applied to equipment for which the heat losses would lead directly or indirectly to an additional consumption of fuel and to those items of equipment for which thermal insulation is required by the process. The thermal insulation is limited to the parts where it is economically justified.

5.1.3 Protection against cold (WT)

The thermal insulation shall be applied to the equipment containing or conveying fluids that can, under the action of cold and in certain conditions:

• solidify (heavy products, etc.),

• crystallise (paraffins, etc.),

• freeze (water),

• give rise to the formation of condensates (fuel gas), circulating continuously or not.

It is therefore designed to delay the cooling of cold-sensitive fluids.

This protection against cold can be associated with equipment tracing. Other cold protection means can be considered (see TOTAL specification GS RM PVA 600).

5.1.4 Personnel protection (PP)

This relates to the parts that can be accessed or are likely to be accessed during operation and servicing procedures on any equipment with a surface temperature greater than 70°C, for an outdoor temperature of 20°C, and not covered by the abovementioned section § 5.1.2.

This relates to the areas situated less than:

• 2 metres above a platform,

• 0.6 metres from a traffic area.

To avoid any risk of burns to personnel, a protective grid shall be positioned around the relevant equipment, so as to prevent any contact without prior dismantling. The use of thermal insulation is allowed for equipment that operates continually and that has an actual operating temperature greater than 150°C.

5.2 Extent of the thermal insulation work

The process data sheet and the line list indicate the equipment that shall be thermally insulated and the type of thermal insulation.

TOTAL specification GS RM PVA 101 indicates for each piping class whether or not the flanges shall be thermally insulated. Generally, the flanges of equipment containing hydrocarbons or in hydrogen operation are not thermally insulated.




Page 9/30

Flanged assemblies are thermally insulated in cases where there is an identified risk of gas condensation that might cause corrosion, a risk of plugging or unacceptable thermal losses:

• risk of formation of corrosive salts,

• risk of product solidification (sulphur, bitumen, etc.),

• flue gas condensation,

• coking of FCC reactor effluents,

• steam or heating fluid lines,

• piping insulated against the cold (WT)...

These assemblies shall not have been calculated in application of a bolting temperature reduction rule (for example, 20% reduction for the temperature of the bolting in accordance with code B31.3).

The thermal insulation work for a flanged assembly shall be carried out in such a way that the protective enclosure and the thermal insulation is easy to dismantle and reassemble. The boxes shall include a drainage device (see drawing CINI 4.1.18).

The parts of equipment that are normally removable and that are to be insulated (such as manholes, valves, removable domes), shall be equipped with removable insulation devices.

The following equipment shall not be covered with thermal insulation:

• Manufacturers' plates when fixed to the wall of the equipment,

• skirt and legs supporting vessels,

• vessels or tanks with internal insulation,

• traps, vent or drain nozzles to the open air, except in particular cases (equipment vents conveying bitumen, sulphur, etc.),

• valves and flanges in hydrogen service,

• piping for vessels designed taking into account a reduced temperature because of the dissipation of heat into the atmosphere.

5.3 Choice of thermal insulation system

The thermal insulation system comprises the following elements:

• anti-corrosion protection for the support when necessary,

• an insulating product,

• a protective cladding against the ingress of water.

Choosing an insulator involves considering all the stresses to which it will be subjected, in order to ensure its effectiveness over time:

• the nature of the equipment (piping, vessel, tank, etc.),

• the material of which the equipment is made,




Page 10/30

• the operating temperature,

• the corrosivity of the environment,

• the mechanical stresses,

• fire resistance, etc.

The system (insulation and protective cladding) is defined using the CINI flow diagram 1.2.01, supplemented with the following comments.

5.3.1 Anti-corrosion protection

Carbon steel equipment with an operating temperature less than 150°C corrodes in the presence of moisture. Such equipment shall be protected by a coating according to TOTAL specification GS RM COR 001.

Equipment made of austenitic stainless steel with a temperature less than 150°C and greater than 50°C can corrode under thermal insulation by pitting or by stress corrosion cracking. Such equipment shall be protected by a coating compliant with TOTAL specification GS RM COR 001.

5.3.2 Choice of insulation

The CINI table 1.2.01 uses temperature as input data. Other considerations shall be taken into account such as:

• fire resistance, on hydrocarbon processing units (light or hot), where the risks of fire are significant, materials of a mineral origin (glass wool, rockwools, calcium silicate, perlite, etc.) shall be employed, and not organic materials that have a low temperature resistance,

• mechanical compression resistance may be a criterion of choice if there is a possibility of passage,

• in particularly humid sectors, an insulator will be selected that does not favour water retention such as cellular glass.

5.3.3 Choice of protective cladding

The external cladding shall protect the insulation over time against the ingress of water and any mechanical impacts. It also has an aesthetic function.

• Fire resistance. On units processing hydrocarbons (light or hot), where the risks of fire are significant, protective claddings made of aluminised plate (CINI 3.1.02) or stainless steel (CINI 3.1.05), which has a better resistance over time, shall be employed.

• In the absence of any fire risk, aluminium claddings (CINI 3.1.01) can be considered. They offer good resistance over time to atmospheric corrosion, but their mechanical resistance is lower. They offer low resistance to corrosion in the presence of acids or bases.

• The use of galvanised steel is not recommended (lower resistance to corrosion). Its use in galvanised and lacquered form is allowed on tanks.

• Equipment made of austenitic stainless steel is sensitive to stress cracking by molten metals, notably zinc. This affects equipment and instrumentation made of austenitic stainless steel. For this reason, the use of galvanised plates or alu-zinc coated plates is strictly prohibited on the units.

• In sectors where humidity is high and/or the fire risk is not predominant, fibre reinforced polyester type organic claddings (CINI 3.2.11), providing a good tightness, can be employed if the temperatures remain moderate (jetty, proximity of cooling tower, demineralisation unit, etc.).

In the case where the thickness of the thermal insulation is too great (case of small diameter piping with circulation interrupted for a long period for example), the Engineering Company shall consider other arrangements (see § 5.1.3 above).

If tracing has to be provided to keep the fluid at a certain temperature, the thermal insulation shall be designed for heat conservation.

6. Thermal insulation thickness

6.1 Heat conservation

6.1.1 General

The thermal insulation thicknesses can be determined:

• either by calculation, taking into account the basic data that is the subject of § 5.2 and the method which is the subject of § 6.1.2. This method shall be given preference for new unit construction projects or major maintenance/upgraded works,

• or based on the tables indicated in Appendix 1. These tables correspond to thicknesses commonly used in Europe.

For each project, TOTAL shall specify the procedure to be used.

In all cases, the immediately higher standardised thicknesses shall be selected.

6.1.2 Determining thicknesses by calculation

Except in the case of personnel protection, the thermal insulation thicknesses shall be determined by minimising the following function:

F = C x CC + OPEX where:

C = Cost of insulation per unit of surface area (m² for flat surfaces and metre for piping). The fixed costs of scaffolding and surface preparation shall not be included.

CC = Capital charge (as a percentage according to the fixed return on investment time).

OPEX = Cost of thermal losses per unit of surface area or of piping length. The thickness adopted shall be the standardised thickness immediately greater than the calculated thickness.

The TICP ("Thermal Insulation Calculation Program") software is available from CINI. It can be used to determine the optimum economic thickness and the thermal losses - See CINI 6.1.00.

Other programs may be approved with the agreement of TOTAL or its representative.

6.2 Protection against cold

The thermal insulation thicknesses shall be calculated by the Engineering Company, according to the information contained in the CINI code, and according to the quantity of heat that may be lost by the fluid.

The design notes shall be supplied to TOTAL.




Page 14/30

6.3 Protection of personnel

For protection arrangements for which the only justification is protection of personnel, preference shall be given to expanded metal-type solutions. For temperatures below 150°C insulating paint coatings can also be used.

The use of thermal insulation is allowed only for equipment in continuous operation and with an operating temperature greater than 150°C.

The thicknesses of the thermal insulation shall be as given in the table in Appendix 1.

The thermal insulation and the function of the thermal insulation shall be symbolically represented on these drawings (see the abovementioned specification).

It should also be remembered that the types and thicknesses of the piping thermal insulations shall be added by the Engineering Company to the list of installation lines.

7.3 Studies

At the request of the Purchaser, the Contractor shall indicate the guaranteed losses (for HC type thermal insulation) or guaranteed temperatures (for WT and PP type thermal insulations), in steady state operation, after insulation.

The losses shall be expressed in:

• watts per square metre of external surface for vessels,

• watts per linear metre for piping.

The use of kcal/h (instead of watts) is acceptable.

The guaranteed losses are valid with usage tolerances (± 10%).




Page 15/30

Any check on the performance levels actually obtained will be carried out contradictorily according to the usual methods, at the request of TOTAL and with costs borne by TOTAL (see § 18).

• the nature of the equipment (piping, vessel, tank, etc.),

• the constituent material of the equipment,

• the operating temperature,

• the corrosivity of the ambient medium.

8.1.1 Thermal insulation designation

The only materials accepted are materials that meet the CINI specification, section 2 (see CINI 2.1.01 to 2.13.01). In addition to the CINI specification, the insulation products shall conform to the specification ASTM C 795 (Karnes diagram).

The use of any other material shall be submitted for TOTAL's written agreement on presentation of the following characteristics:

• nature and chemical composition,

• thermal conductivity coefficients in W/m.K as a function of temperature (nomogram with points in a line or equivalent), perpendicularly to the direction of the fibres and, where appropriate, in the direction of the fibres (see § 8.1.2),

• density in kg/m3,

• fire resistance classification (categories A1 to F) according to the European classification for the reaction to fire of construction products (Euroclasses) bearing classification of materials and construction elements by categories according to their behaviour in response to fire and definition of the test methods,

• optimum usage temperature in continuous operation, that is to say the most efficient with no loss of dimensional characteristics (optimum efficiency zone),

• peak maximum usage temperature,




Page 16/30

• nature and percentage by weight of binder (batching oil and resin),

On receipt of the materials on site, a sampling procedure may be carried out in order to check their conformity to this specification.

8.1.3 Packaging

Fibrous insulating materials shall mandatorily be packaged in plastic packaging and labelled (Manufacturer and material reference).

For prefab section, mention shall be made of the source block on the package label (Manufacturer and material reference).

8.2 Nature and form of the insulation

9. Claddings The claddings are intended to ensure:

• tightness to water run-off (importance of the quality of the seal between mouldings),

• mechanical protection of the insulator,

• protection of the thermal insulation against fire,

• good appearance and cleanliness.

9.1 Preparation of the surfaces to be thermally insulated

Before fitting the thermal insulation, the surface to be thermally insulated shall be cleaned and dried and been successfully hydrostatically tested. For installations in discontinuous operation or in continuous operation with an operating temperature of less than 150°C, the surfaces shall be painted. The painting shall be checked by TOTAL or its representative before the thermal insulation is fitted.

9.2 Fitting the thermal insulation

See CINI 1.3.01 p 5 and 6

9.3 Fitting the cladding

See CINI 1.3.01 p 7




Page 17/30

9.4 Removable insulation

Any thermal insulation for the following items shall be removable:

• flanges with paddle blanks,

• flanges receiving isolating blind seals on unit shutdowns,

• flanges and valves on piping fitted to vessels provided with bypasses making it possible to work on them while the installation is operating,

• main accessories of the circuits that include tracing or jacketed piping. All vessel manholes (towers, flasks, etc.) that are thermally insulated shall be provided with removable covers. Machine insulation shall be removable if possible. For tubular exchangers, the thermal insulation for the channel box and for the shell cover shall be removable.

9.5 Applying the cladding

The attention of the Contractor should focus on the need for maximum tightness of the claddings to the ingress of water. The cladding shall be fitted within a maximum period of 24 hours after the thermal insulation has been fitted. If this period has to be exceeded, the thermal insulation shall be temporarily covered with an impermeable plastic covering. All the plates shall be arranged in such a way as to prevent the ingress of rainwater by run-off (upstream plate shall overlap the downstream plate). In exceptional circumstances, the use of a sealing mastic may be accepted to perfect this tightness, when the skin temperature of the equipment is less than 120°C. All thermal bridges are proscribed (direct contact or contact via a metallic part between the vessel or the piping and the metal cladding).

9.6 Accessibility

The thermal insulation shall not in any way hamper access to the valve or instrumentation for process or maintenance operations. When the thickness of the thermal insulation causes a problem, these thicknesses shall be reduced locally. Cutting of the thermal insulation to reveal a valve hand wheel or a dial is strictly prohibited.

9.7 Covers without thermal insulation

Covers without thermal insulation allow protection against run-off water or bad weather (case of flanged seals on hydrogen operation). They are made without a bottom or insulator and cover only the top half of the part to be protected. Such covers are fixed by screwed tabs (on the existing insulation when possible).




Page 18/30

11.1 insulation support

The support for the thermal insulation shall be made according to the CINI standards or the Engineering Company's standards. In the latter case, these standards need to have been approved in writing by TOTAL. On-site welding of supports on the equipment is strictly prohibited. It should be remembered that, for certain pressure vessels (see TOTAL specification GS RM PVE 001), specific arrangements may be required to allow for the removal of the cladding and of the thermal insulation only in the areas requiring inspections or checks (shell weld lines, manholes, inspection holes, nozzles, taps, certain areas of small vessels).

11.2 Removable items on manholes and hand holes

Manholes on vessels shall be insulated by removable covers. The design of the removable covers is identical to that defined in § 10 above. A cover shall be made in a single piece if it can be removed and refitted by no more than two people. It shall be fixed to the insulation secured by quick release toggle. The tightness between the fixed insulation of the equipment and the removable cover shall be provided by a flexible bead with a diameter of 10 mm. Hand holes shall be insulated by semi-removable (screwed) covers.




Page 19/30

11.3 Wells

Wells shall be provided in the thermal insulation of vessels with a capacity of more than 2 m3 to allow the thickness of the shell plate to be measured with an UTdevice. The diameter of these wells shall be 150 mm. There should be:

• six wells on columns more than 20 m high, including one on each bottom,

• four wells on other vessels of more than 10 m3, including one towards the bottom, one towards the top and two in the middle of the shell,

• three on vessels from 2 to 10 m3, situated towards the bottom. The placement of the wells shall be indicated by the Engineering Company on the drawings of the vessels and submitted for written agreement (see TOTAL specification GS RM PVE 001). They shall be accessible from safety ladders or existing gangways. For each well, a plug of thermal insulation of the same type as that covering the vessel shall be provided, with a cover made of steel plate of the same type as the cladding employed for the rest of the vessel. These plugs shall be watertight.

12. Thermally insulation of tubular exchangers The general drawings relating to the fitting of thermal insulation on tubular exchangers are contained in the CINI code, § 4.0.00.

12.1 General

The rules applicable to sheet metal vessels (see § 11) are applicable to tubular exchangers, subject to provisions contained in § 12.2 and 12.3.

12.2 Exchanger with a nominal diameter greater than 750 mm (30")

The shell, the bottom and the channel shall have a fixed thermal insulation cladding leaving the connecting flanges free to allow for bolting to be fitted and removed. They shall be thermally insulated with separate removable covers in three or four parts with internal thermal insulation. The thermal insulation shall be secured inside the removable items by attachments riveted to the plate. The parts of the covers shall be assembled by means of quick release toggle made of:

• cadmium-plated steel for plates made of aluminium-coated steel,

If the frequency of removal of the covers from the casings and bottoms is greater than once a year, jackets made of padded fabric shall be preferred to the covers. These jackets shall include, at a low point, an eyelet for draining any leaks.




Page 20/30

13. Thermally insulating machinery The general drawings relating to the fitting of thermal insulation on machinery are contained in the CINI code, § 4.6.00.

For heat conservation, the insulation shall be made removable either by covers, or by watertight and fire-proof padding.

For machinery with irregular contours, the insulation may be provided by applying a thermal insulating cement.

14. Thermally insulating storage tanks The general drawings concerning the fitting of the thermal insulation on storage tanks are contained in the CINI code, § 4.5.00.

14.1 General

This specification covers the technical requirements for the design and application of thermal insulation on the walls and the roof of storage tanks for working temperatures between ambient temperature and 180°C.

The maximum/minimum working temperatures shall be mentioned in the tank data sheets.

In the design of the insulation, the frequency of the occurrence of these extreme temperatures shall be taken into consideration.

14.2 Thermally insulating storage tanks

14.2.1 General

The design of the thermal insulation for storage tanks may be divided into three parts:

• tank walls: in accordance with section 6 of CINI, "thermal insulation calculations",

• tank roof: the same approach shall be applied for the roof and the walls of the tank although the heat lost via the roof is less than that lost via the walls of the tank in contact with the product, and the maintenance and servicing of the insulation are much more expensive for the roof than for the walls,

• foot of tank.

The dimensions of the tank, the working temperatures and the loading due to wind shall be included in the design of the construction of the insulation system for the walls and the roof of the tanks.

The insulation systems for the roof are normally not practicable: an insulated tank roof on which it is possible to walk has a special structure that is not described in this specification.

The measurements and dimensions indicated in the insulation/cladding details for the various components shall be considered on the basis of minimum requirements; however, the exact measurements and dimensions of systems not welded to large tanks shall always be determined using calculation tables.




Page 21/30

14.2.2 Insulation system

14.2.2.1 General

The insulation system shall be strong enough to withstand the wind loading and pressure for a long period (approximately 20 years). Also, the insulation system shall be capable of absorbing the deformations of the tank due to the temperature variations, the loading or unloading, etc., so that the cladding retains its water-repellent properties.

14.2.2.2 Tank walls

Tanks with a diameter greater than 12 m:

• A corrugated plate cladding shall always be applied.

• If welding on the tanks is permitted, preference shall be given to the simplest and most reliable system.

• If welding is not permitted, a suspension system shall be applied:

− preference shall be given to a wall-mounted suspension system in the case where a steel bar reinforcement may be fixed around the walls of the tank and the reinforcement can withstand thermal expansion due to the release of heat from the tank and in the case where the tank is in continuous operation;

− preference shall be given to an external suspension system in the case where the tank is not frequently in operation since this system is more flexible given that the fixings can be adjusted distance-wise, but for this reason the system is less resistant to high wind loadings.

Tanks with a diameter less than 12 m:

• A flat or corrugated plate cladding may be applied.

• If welding on the tank is permitted, preference shall be given to a welded system covered with a corrugated plate cladding.

• If welding is not permitted, a suspension system shall be applied.

• Small diameter tanks may be covered with a flat cladding:

− tanks with a diameter less than 6 m: insulate like a vertical vessel, provided that it has sufficient fixings available to secure the insulation system. In case of violent winds, a securing strip may be installed on the back of the joint ring, in accordance with CINI 4.5.03 detail B.

− tanks with a diameter from 6 m to 12 m and on which welding is permitted: the insulation system described in CINI 4.5.03 may be applied.

− tanks with a diameter from 6 m to 12 m and on which welding is not permitted: the insulation system described in CINI 4.5.04 may be applied.

The walls of tanks may be insulated with one or more layers of mineral wool panels. In specific cases, the application of different materials may be considered.




Page 22/30

14.2.2.3 Tank roof

The tank roofs shall be insulated with very rigid mineral wool panels in one or more layers. In specific cases, the application of other materials may be considered. A certain degree of ventilation shall be created in conjunction with a possible evacuation of condensation water.

For the covering of the insulations of miscellaneous roofs, cladding systems are available.

For tanks with a diameter less than 12 m radial segments with raised flanges shall be used to cover the insulation panels. The segments and the insulation panels shall be anchored to the roof of the tank by means of stainless steel clamps around the spiral welded to the roof.

CINI 1.3.04 page 5, CINI 4.5.07 to CINI 4.5.09.

14.2.2.4 Tank bottom

In certain conditions, the tank bottoms shall also be insulated.

This applies for:

• tanks for which the working temperatures are high and which stand on a concrete foundation,

• tanks containing products with a low solidification temperature,

• economic reasons.

The insulating materials used shall have a sufficiently high compression resistance to withstand the load without undergoing deformation, such as, for example, foam glass.

Between the bottom of the tank and the insulating layer, a layer of bituminous sand (tar) shall be applied for the distribution of pressure. In the case of large tanks, a ring of concrete shall be arranged below the tanks so that they can be filled with insulating material.

14.3 Application

The thermal insulation is covered with cladding, which is fixed to securing strips with self-tapping screws.

Corrugated plates are fitted with an overlap of at least one corrugation in the horizontal direction and a vertical overlap of at least 50 mm.

System 2: With cladding made of flat plates, tank diameters less than 12 m

Rigid insulation panels shall be installed along the walls of the tank and fixed using stainless steel straps; three per panel, two at 150 mm from the edges and one in the middle of the panel.

The securing strips shall be fitted around the thermal insulation and provided with safety devices (springs).

The securing strips shall be installed with or without spacers and/or suspension strips. The thermal insulation shall be covered with a cladding fixed to the securing strips using self-tapping screws; horizontal and vertical overlap of 50 mm.




Page 23/30

14.3.1.1 Suspension system on the wall side with support spacers

The suspension strips are suspended against the walls of the tank and then the fixing strips are fitted around the tank. After the spacers have been fitted, the fixing strips are secured using clamping nuts. The aluminium ties are then closed on the clips of the spacers.

The flexible insulation panels are positioned from bottom to top on the tank and they are clad over their entire length with corrugated plates, which are fixed to the attachment system using self-tapping screws.

During installation, the insulation panels are placed behind the cladding plates. The corrugated plates are fitted with an overlap of at least one corrugation in the horizontal direction and a vertical overlap of at least 50 mm.

For tanks with a diameter less than 12 metres, but with a height greater than 12 metres and working at elevated temperature, at least one expansion joint shall be placed every 10 metres, depending on the design of the tank (see CINI 4.2.11).

In the case where reinforcing rings have to be installed, for suspended insulation systems, an independent system shall be applied on both sides. The reinforcing rings are then separately insulated, but this depends on the tank criterion.

The placement of the holes drilled for the plate screws shall be determined by trial and error, depending on the thickness to be joined, the type of material, and so on. The self-tapping screws shall be taken into account in the work.

The strips, made of 50 x 0.5 mm stainless steel, shall be placed on the outside of the cladding plates, at least one for each plate level (see CINI 4.5.03). For safety, these strips are attached to the cladding using "S" type ties. Springs shall be installed to absorb any expansion.

Around the relief and the connection nozzles of the tank, the cladding is cut to shape and then made impermeable with a lining or an adhesive material. This material shall have mechanical properties to enable it to absorb any movements.

The upper part of the insulation wall shall be correctly installed under a water repellent. Under no circumstances should water be allowed to penetrate into the insulating wall.

After the storage tank has been started up, all the reliefs of the insulation system shall be inspected. Similarly, when the installation is operating normally, the insulation system shall be regularly inspected.

14.3.1.2 Tank roof

TOTAL shall specify in each case whether the roof has to be thermally insulated. If it does, the Contractor shall submit the detailed thermal insulation procedure for TOTAL's written agreement.

The insulation panels shall be attached to the roof of the tank.

Cladding with raised edges shall be installed in accordance with the design arrangements and shall be anchored to the roof using stainless steel clamping strips.

A rainproof sheet shall then be installed on top of the flanges and fixed using stainless steel screws.

The reliefs and/or vents passing through the insulation shall be protected against water and ventilated, as indicated in CINI 4.5.11.




Page 24/30

After startup, all the protusions and vents passing through the insulation system shall be inspected.

15. Inspection and testing When the materials are received on site, TOTAL's representative may take samples from each batch. These samples shall strictly conform to those indicated in the bid.

Any defective parts shall be scrapped.

The thickness of the thermal insulation shall be checked during the works. TOTAL shall check that the fitting and the application quality of the thermal insulation and the coating are in accordance with the requirements of this specification.

16. Quality control

• finally, check that there is no degradation.

17. Acceptance of the works

17.1 Acceptance

The acceptance of the works shall be in accordance with the General Conditions of Execution for Supplies to TOTAL.




Page 26/30

17.2 Thermal performance inspections

These inspections of the installed thermal insulation may be carried out by a third party at the request of TOTAL and with costs charged to TOTAL.

They shall be carried out when the installation are in steady state operation.

When TOTAL decides to carry out these inspections, the Purchaser shall draw up, or arrange to have drawn up, preparation documentation for the corresponding tests, including:

• the data used to calculate the thicknesses (see § 5.3 above),

• the physical organisation of these tests, bearing in mind that:

− the inspections shall be carried out by a specialist organisation accepted by common agreement by the Contractor and the Purchaser,

− the inspection methods and means are proposed by the organisation which also has to draft the final report,

− the Purchaser shall define the identification on site and on the drawings of the measurement points, and shall establish the means of accessing these points (scaffolding, ladders, etc.),

− thermal performance inspections shall be carried out for the first time no later than 6 months after provisional acceptance, a second time a little before the warranty period expires,

− the costs of these inspections continue to be borne by TOTAL,

− excess loss is measured globally on all the points inspected.

18. Warranties The warranty period for the thermal insulation is 5 years, from final acceptance.

The warranty includes materials, fitting works, thermal effectiveness and tightness of the covering.

A reduction in the warranted thermal effectiveness caused by aging of 1% per year counted from the date of provisional acceptance of the works is accepted.

1. Scope

This specification covers the minimum requirements for complete external insulation systems forhot, cold and acoustic services on surfaces of piping, equipment, instruments, etc.

This specification does not cover underground systems, internal insulation and insulation ofbuildings.

It is important to note that for new units this specification could be incomplete and does notcover all services. In this case licenser, TOTAL group and engineering contractor specifications(job specifications) shall be considered as well.

For revamp works original job specifications and licenser requirements shall be checked againstthis specification. In case of conflict the most severe prevails.

In case there are items not covered by this specification, the engineering company shall checkthe specifications of the TOTAL group, if the item is still not covered, the engineering companyshall spontaneously and at no cost submit its own specification for approval.

For deviations of the Total Raffinaderij Antwerpen (hereafter called TRA) Spec. "P" a waiverrequest shall be issued for approval to TRA Engineering Department. Only the head of TRAEngineering Department can approve deviations. Requests to change this specification shall bemade using the form DP-P003-F001.doc “aanvraag tot specificatie of standard wijziging”.

Remark:This specification is not restrictive. Modifications or alterations can be done after approval ofTotal Raffinaderij Antwerpen (TRA) Engineering Department.

1.2. Definitions

The temperatures in this specification are to be read as normal operatingtemperatures unless specifically indicated otherwise.

Thermal conductivity of insulation base materials is expressed in W/mK at the givenmean temperature of the insulation.

Maximum permitted temperatures for fibrous insulation materials are meant to be theclassification temperatures as measured per AGI Q 132.

Nominal piping diameters including all appurtenances are stated as NPS, forexample a 12" line, as NPS12.

Vessels means process vessels. Total Raffinaderij Antwerpen (TRA) and/or principal or its representative is further

referred to as OWNER. Insulation contractor and/or any other performing insulation work is further referred to

as APPLICATOR. c.t.c. means center to center. VB means vapour barrier. PP means personnel protection. Jacketing means weather proofing metal sheeting constructed to a close fitting cover

of the base insulation. HC means heat conservation.

1.3. Piping and vessels

Piping above NPS 24 is to be insulated with same thickness and method as vessels. Vessels and equipment having a diameter of 24 inch and smaller shall be insulated

with same thickness and method as piping of that size.

2. Insulation materials

2.1. General

1. Asbestos and asbestos containing materials are not permitted.- For Lump Sum Contracts and for skid-mounted units the applicator shall -at completion-

certify in writing to owner that asbestos is not present in his work.- For jobs initiated by work orders asbestos free must be certified separately.

2. Ceramic fibres may be hazardous to health.Where application for high heat service (> 700°C) is unavoidable, applicator is to requestfor permission with submittal of his health procedures.If permitted by owner, applicator shall duly register location and extent for futurereference. If permitted the fibres shall be have a Ø > 6 microns.

3. Zinc or zinc containing material shall not be used on or above stainless steel piping,vessels and equipment.

4. Insulation base material chloride content should meet de requirements of ASTM C795.

5. The water absorption, measured according AGI Q 136 shall be lower than 10 % byvolume.

6. Only one type wool is permitted on a job. Applicator shall indicate his choice already in hisbid.

7. Properties of supplied material shall not deviate more than 2 % from those specified inthis specification.

8. When economically attractive, applicator may propose in his quotation alternativeproducts, technically matching those specified here under, for acceptance by owner.

9. Materials shall be non-combustible according ISO 1182 and NBN S-21-203.
