From the early seventies, the realisation that natural resources are not inexhaustible has

grown and is now shared by an increasing number of players.

The signs are become evident: difficulties in recycling some products at the end of their

useful life, exhaustion of fossil fuels, increasing shortage of water resources, climate

change caused by greenhouse gases, etc.

Faced with these issues, local authorities need to consider the long term environmental,

financial and social impacts of the public decisions they are making.

The information available regarding the condition of the water systems is still not

accurate enough in view of the high stakes. Statistical studies that have been conducted

on the installed system show that the potable water supply networks alone represent

more than millions km of pipelines, out of which 1/3 are in questionable condition, with

the average leakage rate being estimated at about 25 %.

The networks are ageing and it would take over a century to replace them completely,

at current rates. Scenarios are being prepared, based on a realistic time scale and on the

evaluation of the costs that will be incured.

Initial replacements in the networks are carried out for statutory reasons and priority

replacement will probably be the relatively large diameters in more densely populated

regions, in other words the most critical and expensive.

Within the next few years, these priority renewals and others - some grey iron pipes are

over 100 years old - will lead to a sharp rise in the sums allocated to water issues by the

authorities.

These studies highlight the need to invest in sustainable systems and take into account

true investment cycles, quite unrelated to accounting amortisation periods.

Stick to your principles

Whilst retaining the traditional advantages of ductile iron:• robustness and reliability of the pipeline systems,• quick and easy to install push fit joints, the NATURAL range offers several advantages: • it considerably extends the field of use of ductile iron pipeline systems, • pipes can be installed without a systematic soil survey and without

additional on site protection, in over 95 % of the ground types encountered,

• it significantly increases the lifetime of the pipeline.

In many countries, cast iron is a historic reference material, used in the first water systems. SAINT-GOBAIN PAM is itself a technical reference: for more than 150 years, the company has capitalised on the exceptional qualities of a material which has stood the test of time whilst continuously striving to improve and develop it. The permanent search for perfection and a concern for quality mark out SAINT-GOBAIN PAM as the world leader.

Since most water supply work is carried out in the diameters DN 60 to DN 600, NATURAL pipes are now coated up to DN 600 in order to build even longer lasting homogeneous networks.

PAM NATURAL blue ductile iron pipe system is THE simplest and most universal system available on the market.

SAINT-GOBAIN PAM is currently extending the NATURAL range with a series of major innovations:• Extension to diameters 350 to 600,• Standard Vi self-anchored joints extended to diameters 350 to 600,• NATURAL UNIVERSAL for the most demanding applications,

In 2000, SAINT-GOBAIN PAM launched the NATURAL range, a ductile iron pipeline system, from DN 60 to 300, with a patented anticorrosion external coating. At the time, the innovative multi-layer coating on NATURAL pipes represented a major technical revolution.

Stick to your principles

SAINT-GOBAIN PAM, more than 150 years of history and know-howFounded in 1856, SAINT-GOBAIN PAM is the world leader in the manufacture and commercialisation of ductile iron pipeline systems.

The emphasis placed on research and development has enabled the company to combine traditional know-how and technical innovation to continuously offer its customers high quality, reliable and ergonomic products.

A material built to last

Buying a pipeline is a major investment. The installed network must therefore be durable.

Thanks to the qualities of ductile iron, the pipelines can withstand unpredicted occurrences on site and unforeseen changes in operating conditions:

• Increased service pressure (increased requirements).

• Accidental excess pressures.

• Water hammer.

• Migration of the trench bottom, placing the pipeline in contact with rocks likely to pierce the pipe or cause breaks.

• Future work, carried out nearby, damaging the pipeline (for example, by a mechanical shovel).

• Ground movement, settlement.

Equipped with elastomeric joints, ductile iron systems form adaptable and flexible systems which can withstand external loads caused by the backfill, whether the depth of cover is large or small, as well as the site contingencies which may occur despite the precautions taken.

Installation of PAM ductile iron networks, simplified by the use of modular and fully compatible components, guarantees achievement of design performance levels, even under the most difficult laying conditions.

The mechanical properties of ductile iron are stable over time and remain constant throughout the life of the network.

The zinc-aluminium anticorrosion coating, adopted by SAINT-GOBAIN PAM, is another factor which significantly increases the lifetime of the pipelines.

By choosing a strong and reliable material, with a high safety factor, the water undertaking makes a responsible decision guaranteeing continuity of service and the long-term future of the installation.

Ductile iron

Ductile iron is an iron/carbon/silicon alloy containing pure carbon in a spheroidal graphite form.> Exceptional mechanical properties• Elasticity (Re ≥270 MPa)• Breaking strength (Rm ≥ 420 MPa)• Impact strength• High elongation (> 10 %)

> A fully recyclable natural materialAn alloy of iron, carbon and silicon, ductile iron is a "noble material" that can be 100 % reused, indefinitely.It can be completely recycled with no loss of properties and for the same application, in non restricting and non hazardous industrial processes.Recycled cast iron is used as a raw material in traditional steel and iron processes.The Pipe Division of the SAINT-GOBAIN Group produces a large volume of cast iron in its European plants, mostly derived from recycled ferrous materials. It is ISO 14001 certified.

The advantages of a complete rangeFor over 150 years, SAINT-GOBAIN PAM has developed unequalled know-how in the field of water supply, building up countless project references. Based on this experience, the company is in a position to offer:

> comprehensive, uniform ranges to cater for all types of site configuration,

> modular pipeline systems, with coherent design:Pipes, all types of fittings, flanged connection parts, connecting and repair pieces, parts for valves and fire hydrants. All SAINT-GOBAIN PAM products are fully compatible, playing their part in the construction of watertight, durable structures.

Laying of ductile iron pipes by microtunnelling.

A material you can trust

A material which has stood the test of time

Ductile cast iron combines the traditional longevity of cast irons with exceptional mechanical properties: elasticity of the metal, bending strength due to high elongation capacity, resistance to ovalisation, solidity and proven performance of over a century.

Due to these exceptional mechanical qualities, ductile iron is suitable for all types of terrain and can withstand high stress without damage (deep or shallow depths of cover, traffic loads, other site contingencies, etc.).

This explains why ductile iron, and now the Natural range, has long been considered as the reference material for hydraulic networks, and especially pressure pipelines.

Over 10 000 km of SAINT-GOBAIN PAM-designed ductile iron pipelines are laid every year

Sanitary compliance

The materials used by SAINT-GOBAIN PAM intended for contact with drinking water (coatings, elastomers, lubricating paste) have received Sanitary Compliance Certificates in France, United-Kingdom, Germany, Netherlands, ...

ServiceSAINT-GOBAIN PAM provides a local service through its Regional Offices.

Always available, the company's teams of engineers and technicians offer technical expertise and support to customers in Europe and throughout the world: design support (hydraulic calculations, mechanical calculations, water analyses, soil surveys, etc.), on-site assistance, after-sales service, etc.

Trenchless pipe laying!

Inspired by the techniques used for laying flexible cables, trenchless p i p e l a y i n g techniques can be implemented when laying ductile cast iron pipelines.

In both the "microtunnelling" technique, used to cross single points (roads, waterways, etc.), and the "trenchless pipe replacement" technique, used to replace an old pipeline, a tapered pulling head pulls a line of cast iron pipes, pre-jointed and self-restrained by anchoring, through the ground.

UNIVERSAL Ve pipes protected by the TT coating are perfectly suited for these laying techniques.

Logistics

Efficient logistics is based on the ability to reduce the time between expression of need, delivery, commissioning.

The numerous regional depots cope with the significant increase in the number of requests and guarantee immediate availability of the standard products.

Whenever possible, SAINT-GOBAIN PAM also delivers ready-to-lay components: delivery in kit form of EXPRESS and EXPRESS Vi junctions in the NATURAL range as well as kits of flanged joints simplifies work on site.

Quality

For SAINT-GOBAIN PAM, the notion of performance extends far beyond the products. It involves the entire company, from product design through to delivery.The SAINT-GOBAIN PAM Quality Assurance system is based on the standard NF EN ISO 9001-2008 which certifies control of the main processes (design, production, commercialisation).All the plants responsible for manufacturing products in the NATURAL range have been awarded this certification, issued by an external organisation.

Compliance

SAINT-GOBAIN PAM products comply with national and international standards EN and ISO. Compliance is certified by third party organisations.These standards define the product or service in terms of result; each product, pipe or fitting, is individually tested in the plant, during an internal pressure test.

Detail of the structure of the external protection of NATURAL pipes.

The external coating of NATURAL pipesNATURAL pipes benefit from a new generation of active zinc-based external protection offering far greater performance. This blue coating consists of a zinc-aluminium alloy and an epoxy coating developed in our Research and Development Centre, tested under real conditions. While remaining robust and easy to lay, NATURAL ductile iron pipes are easier and safer to use and are suitable for a broader range of applications.

A complete pipe system

Increased versatility

Capitalising on the company's research, knowledge of soils and skills in the field of alloys, SAINT-GOBAIN PAM proposes with NATURAL a full range of ductile iron pipelines, compatible with more than 95% of the most frequently encountered soil types. NATURAL is a complete range:

> which removes the need for systematic soil surveys,

> which can cross corrosive sections without risk, with no need for additional protection using a polyethylene sleeve, and therefore with no extra site cost,

> which simplifies the management of small diameter pipeline inventories,

> which limits the number of cases where the TT-PE range must be used.

The external coating of NATURAL pipes is based on the principles and experience gained by SAINT-GOBAIN PAM over 40 years with zinc coating, recognised by European and international standardisation organisations.

It greatly improves the efficiency and scope through 3 effects:

> metallisation of a new zinc-aluminium alloy on the surface of the pipe. The type of two-phase alloy chosen (85 % zinc and 15 % aluminium by weight) has been optimised to obtain:

• the galvanic protection effect of zinc (damage protection),

• increased ability of the coating to heal itself in a wide range of soil types due to the presence of aluminium,

> the quantity of protective alloy (400 g/m2) has been doubled compared with SAINT-GOBAIN PAM's traditional zinc coating (200 g/m2 of zinc) and doubled compared with the minimum level set in standard NF EN 545-2010 (200 g/m2 of zinc). The benefit on the period of active protection is considerable, proportionally far higher than the increase in quantity,

> the finishing layer now consists of a blue epoxy pore sealer. Perfectly compatible with potable water, the blue epoxy replaces the traditional black bituminous paint and ensures correct operation of the active protection.

Metallisation is carried out by spraying on the liquid zinc-aluminium alloy. This unique process, developed by SAINT-GOBAIN PAM, guarantees optimum efficiency of the external protection.

Remark: The few cases where the NATURAL range is unsuitable are easy to identify by a simple qualitative examination of the pipeline layout. These exceptions, for which we recommend the use of the STANDARD TT range, concern:• ground located in a saline water

table,• acidic peaty ground,• subsoils polluted by uncontrolled

mining or industrial waste,• subsoils with uncontrolled stray

currents.In this case - and in the absence of any additional information - use the TT-PE range (pipes coated by coextrusion with a thick polyethylene dielectric coating, bonding to the ductile iron, in compliance with the European standard EN 14628-2006).

Express fittingof the NATURAL range

Standard fitting of the NATURAL range

Coating of fittings in the NATURAL rangeNATURAL blue iron is a coherent range: the NATURAL pipes with STANDARD joints are used with EXPRESS or STANDARD joint fittings and accessories, for which all components (body, glands, bolts, etc.) are given reinforced coatings.

With their zinc-aluminium coating, NATURAL pipes have an extended field of use. Due to the method of manufacture (sand cast) and their complex and varied geometry, the coating used on fittings is not technically identical to that used on pipes but fittings in the NATURAL range have also benefit from a new protective layer, replacing the traditional black bituminous paint.

This new coating is formed by combining chemical treatment of the ductile iron surface and a blue epoxy coating deposited evenly by cataphoresis.

NATURAL blue iron

Anticorrosion performance

SAINT-GOBAIN PAM has demonstrated the performance of Natural by tests carried out in the laboratory (accelerated corrosion) and in natural ground for more than 30 years. It is based on SAINT-GOBAIN PAM's unique expertise in this field, acquired with zinc coatings.

A few illustrations are given below:> the double effect of the amount of protective metal and the type of alloy extends

the field of use well beyond that possible through the use of zinc alone.

DN 60 to 600

> behaviour in corrosive ground: example of a severe test carried out in highly corrosive ground (beyond the normal field of use of zinc!).

> the galvanic protection of the zinc-aluminium alloy selected protects the ductile iron (as with zinc) even when it has been damaged.

> On leaving the foundry, cast parts are carefully shot-blasted before treatment.

> The parts then undergo surface passivation (zinc phosphating) by passing through a bath.

> A layer of blue epoxy resin is then electro-deposited by cataphoresis, producing a layer of highly regular thickness (especially on the corners, etc.).

> The epoxy coating is 70 microns thick.

> Fittings coated with blue epoxy 250 µm, according to EN 14901, can be supplied.

EXPRESS fittings are only available with cataphoresis coating. STANDARD fittings are available with cataphoresis or with epoxy 250 µm. NATURAL UNIVERSAL and TT , STANDARD and UNIVERSAL, fittings are only available with blue epoxy 250 µm.

Accessories

All parts associated with the NATURAL range are protected:

> ductile iron glands for EXPRESS joint by blue epoxy deposited by cataphoresis (70 µm),

> ductile iron bolts for EXPRESS joint by black cataphoresis epoxy (70 µm),

> ductile iron nuts for EXPRESS joint by galvanisation (70 µm),

> branch collars and valves by epoxy powder coating.

Resistance to internal pressure > In compliance with the specifications of the standard EN 545:2010,

the pipes and fittings offer a significant safety margin beyond their nominal operating pressure, the PFA (Allowable Operating Pressure): the safety factor is greater than 3.

> In addition, ductile iron does not age and retains its mechanical strength over time.

> The PFA values* of pipes and fittings in the NATURAL range comply with the standard EN 545:2010 (Appendix A) and is always greater than 40 bar in sizes DN 60 to 300 and greater than 30 in sizes DN 350 to 600.* refer to the table on page 16 for the PFA values and the internet site.

The solution for potable water

Centrifuged cement mortar

The standard internal protection of NATURAL pipes consists of a blast furnace cement mortar applied by a centrifugal process and is manufactured with potable water in accordance with the European Directive GB/33/CEE.

The centrifugal process offers the advantage of producing a compact mortar and a smooth internal surface.

This process results in the following properties: > low porosity of the mortar,

> excellent adhesion of the cement,

> low surface roughness.

The pipeline layout may include soft or unstable ground (marshy areas, subsidence caused by pumping ground water, mining ground, consolidation of road backfill, etc.).Pipelines must adapt to the ground movements and be able to withstand the mechanical stresses applied during these movements.Within their limits of angular deflection and withdrawal, the STANDARD socket joints allow the pipeline to adapt to the deformations imposed by the ground movements.

The internal cement improves the hydraulic flow

The internal surface of the cement mortar has low roughness, which improves flow and reduces head losses. This mortar guarantees consistent hydraulic performance over time (absence of deposits).The roughness coefficient (COLEBROOK formula) of a pipe alone is k = 0.03. In practice however, SAINT-GOBAIN PAM recommends using the value k = 0.1 when designing networks, to take into account the singular head losses of a complete pipeline.

The internal cement protects the pipeline and the potable water

> Protective mechanisms The cement internal coating does not act as a simple barrier, but protects the ductile iron by a passivation mechanism: after being put into service, water gradually saturates the cement mortar and becomes richer in alkaline elements; on reaching the metal wall it is no longer corrosive.> Filling of cracks Crazing which can be seen on the surface of the mortar, even when formed during transport, storage or laying, closes up under the combined effect of two reactions:• swelling (fast) of the cement mortar on filling with water,• hydration (slow) of the component elements of the cement.

Special cases

European directive 98/83/CEE concerning water intended for human consumption sets water quality criteria. However, if the water transported is aggressive (hardness < 5°F) or corrosive and if the residence time in the network is abnormally long (more than several days), or if the chemical composition must not change during transit in the pipeline (mineral water), the NATURAL PUR range should be used.

Safety

Unstable ground

SF safety factor = 3e = minimum thickness (mm)Rm = tensile strength = 420 MPaD = diameter (mm)PFA = allowable operating pressure (bar)

PFA = Design bursting pressure = 20 x e x Rm SF D x SF

Safe, economical laying

A buried pipeline is subject to vertical loads (weight of backfill, traffic loads) which it transmits to the ground via the trench bottom and the backfill.

Considerable forces are involved and there is an interaction between pipe and soil.

Generally, to perform their role the layers must be chosen and compacted according to:

> the pipe's ability to withstand local forces: risks of piercing or damage which could lead to cracks or create faults in the pipe wall,

> the rigidity and strength of the pipe.Robust and strong, ductile iron pipes minimise the trench bottom and surround work, so the work involved in laying is safer and cheaper.

The PUR lining is available in the NATURAL range

For more information about our self-anchoring solutions, please see our SELF-ANCHORING brochure

The Vi solution for self-restrained pipelinesSelf-anchored pipe and fitting joints (STANDARD Vi and EXPRESS Vi) can be used to produce self-restrained ductile iron pipelines.

This represents an attractive solution when construction of concrete thrust blocks would be difficult (land with poor cohesion, risk of future excavation work, problems of space) or when this would delay the project.

The advantage of STANDARD Vi and EXPRESS Vi joints is that they can be fitted on any pipe or any fitting in the NATURAL range.

Choice of elastomers

The EPDM elastomers used for the joints gaskets are fully compatible with the transport of potable water, and are selected by SAINT-GOBAIN PAM according to strict criteria taking into account their intrinsic physico-chemical characteristics and their durability over time. They ensure that the joints in the system are completely tight to internal and external pressures throughout the lifetime of the main. The joint gaskets comply with standard NF EN 681-1

The STANDARD joint

The STANDARD joint is a push-fit joint. Watertightness is produced by compression of the elastomeric gasket during assembly by insertion of the spigot in the socket. The joint is designed (servo-action) so that the contact pressure between the elastomer and the ductile iron increases as the pressure in the main increases. During a destructive pressure test, the pipe will burst before the joint leaks.

The EXPRESS joint

The EXPRESS joint is a mechanical joint. Watertightness is achieved via radial compression of an elastomer joint gasket, using a gland tightened by ductile iron bolts.Little force is required to assemble the EXPRESS joint.Orientation and final positioning of the fitting are easy before tightening the bolts, making this joint highly appreciated in cramped conditions and during maintenance work.

Flexible joints

The STANDARD and EXPRESS joints can tolerate a high degree of angular deflection, to negotiate large radius curves without the need for fittings and adapt to any changes in layout.Combined with the end play, these joints can also absorb ground movements or expansions of small amplitude.

Self-anchored jointsJoints

UNIVERSAL Standard for anchoring at very high and extreme pressuresWhen the network operating pressures exceed the performance of the STANDARD Vi or EXPRESS Vi systems, UNIVERSAL anchoring must be used.

In the UNIVERSAL range, sealing and restraint are achieved in two separate chambers, in order to reach unequalled performance levels.

The angular deflection of STANDARD joints

increases from 3° to 4° in the range DN 350 to 600!

UNIVERSAL Vi for very high pressuresAnchoring is obtained by a system of inserts housed in a chamber located upstream from the sealing chamber.

The NATURAL UNIVERSAL Vi range

now includes DN 80 to 600

UNIVERSAL Ve for extreme pressuresAnchoring is obtained by a system comprising a metal ring housed in a chamber, located upstream from the sealing chamber, which presses against a metal bead on the spigot of the pipe or fitting.

The NATURAL UNIVERSAL Ve

range now includes DN 100 to 600

The STANDARD Vi joint gasket for anchoringThe STANDARD Vi self-anchored joint gasket and the STANDARD joint gasket have the same shape and fit in the same pipe socket. The STANDARD Vi gasket, however, has metal inserts which bite onto the spigot of the inserted pipe after assembly and pressurisation.

It can be used from DN 60 to 600 for pipes and fittings.

The STANDARD Vi range is now available up to DN 600
