A radially-bolted mechanical pipe connectionwhich allows quick make-up and break-out andis ideal where space, weight and joint integrityare critical requirements.

Techlok Clamp Connectors are the most effective and economical pipe connection

system available today. Typically several Techlok joints can be installed in the time it

takes to assemble a single standard ANSI or API flange.

Conventional ANSI or API flanges with their eight to 24 bolts require accurate

alignment to ensure a seal, whereas Techlok Clamp Connectors have only four bolts,

no alignment problems and require less bolt loads.

As is well known, external bending forces are an inevitable part of any piping

system, resulting in high stresses being placed on pipe joints. Independent strain gauge

and destructive tests have shown the Techlok connector can withstand considerable

bending moments/forces and axial loading under pressure without leaking or the bolts

becoming loose, greatly reducing maintenance costs at the same time as being highly

beneficial to the environment.

High pressure systems are not a problem, with Techlok connectors working in

applications where pressures of 30,000psi and above are found; and when it comes to

offshore applications where topside loading is critical, Techlok’s low weight is a real

advantage - a factor applicable in any industry where weight and overall installation cost

is a consideration.

Corrosive applications

In more corrosive applications where the specifications demand the use of exotic

materials, the sheer size difference between conventional flanges and Techlok Clamp

Connectors (typically 75%) ensures operators and contractors a real competitive

advantage when determining capex/opex budgets.

But it’s not just size and weight that makes Techlok the natural choice.

Unlike conventional ANSI flanges, Techlok Clamp Connectors are bolted radially to

the pipe, not along its axis. This means that the clamp can be orientated in any position

around the pipe, and together with their greatly reduced size, this eliminates clearance

problems and enables critical components like valve hand wheels to be aligned to their

optimum positions before fully tightening the clamp bolts.

Some of the Benefits

As well as high performance, leak-free, competitive price and greater efficiency

Techlok connectors have many other advantages over conventional flanges:

• Up to 75% lighter and significantly smaller than a comparable ANSI or API flange

• Close piping and hook-up arrangements with typically 25% smaller clamp diameter

• Typically 40% shorter connection length

• Easier fabrication and installation with no bolt holes to align

• On sizes up to and including 36”, only 4 bolts to tighten rather than up to 24 on a

conventional flange

• The clamp can be rotated round the hub for easy bolt orientation and tightening

• Ancillary components such as valves and piping layouts can be installed without

worrying about bolt hole alignment

• Quicker and easier make-up and breakout minimises maintenance downtime

• Lower bolt torque: typically 50% less than that for a ring joint flange

• Sealing integrity is unaffected by over-tensioning bolts

• Short make and break times - several Techlok connectors can usually be assembled

or disassembled in the time it takes for a single ANSI or API flange connection

• It is not usually necessary to re-tighten bolts once in service

• In most cases only one clamp size is required for each nominal pipe size

• Unlike spiral-wound gaskets, reusable sealrings give greater flexibility for

hydro-testing and commissioning prior to service

• Reduced inventory

• Readily available machining details for interface with associated equipment such as

valves, pumps and metering equipment

• Available in all materials to suit the piping specification

Fully Assembled

Pressure Energised Seal

Prior to Assembly

Self Energised Seal

The Techlok advantage

The heart of Techlok’s success is the energised seal. Techlok clamp connectors do not

rely on the conventional flange’s gaskets and correctly tensioned bolting to maintain the

integrity of the seal. The four basic elements of the Techlok clamp connector are hubs,

sealring, clamps and bolting. When bolting the assembly, the hubs are drawn together by

the twin wedge action of the two clamp segments compressing on the seal ring to make

the first-stage self-energising seal.

The applied bolting loads are transmitted to the clamps through almost 360º contact

with the hubs. And as the bolts are transversely mounted they are almost completely

isolated from the operating loads, resulting in a strong, reliable yet compact connection.

In service the sealring becomes even more effective as internal pressure reinforces the

metal-to-metal seal to the extent that its strength can normally exceed the burst pressure of

the connected pipe.

Techlok Components

Hubs

A critical feature of Techlok hubs is their conical seat which creates the

interference with the sealring lips to make the seal. Hubs are

manufactured from the same generic material as the piping

system on which they are to be utilised. They are then either

welded to the pipe or machined integrally onto associated

equipment such as valves.

Butt weld hubs are supplied with standard ANSI B16.25

weld profiles. Blind hubs are also

available for blanking off a pipe

section or for pressure

vessel closures.

Clamps

The two Techlok clamp segments make

virtually 360º contact round the hubs. The seal is

made when the bolts are tightened, drawing the

two clamp halves together and clamping the hubs

against the sealring. The clamp bolt holes have

spherical seats to accept the spherically faced nuts

to ensure a perfect fit.

Bolting

Techlok clamp connectors come complete with

standard size nuts and bolts in a variety of coatings

to suit every type of piping application. Each

connector requires only four bolts (which

encompasses a 100% safety / redundancy factor)

and the nuts are spherically-faced to eliminate

bending stresses in the bolts during assembly.

Sealring

The key to the Techlok system is its

sealring. Techlok’s sealring has a central rib

section and two seal lips tapered to match the

conical seat profile of the hubs. It is these lips

which make the pressure-energised seal.

Deformation remains essentially elastic throughout, making the

sealring reusable.

The rib provides a positive stop during make-up, preventing the lips

from being crushed by over tightening and also transferring compressive

and bending loads from one hub to the other.

Sealrings are manufactured from high strength steel compatible with the hub

materials. Typically, precipitation-hardening stainless steels such as grades 630 or 660,

or Alloy 718 are specified for corrosion resistant applications, while low alloy steels are

used for carbon steel pipes. Coating the sealring with a lubricant such as PTFE prevents

the surfaces galling during make-up and enhances reusability.

4

Techlok's sealring has many advantages

over conventional gaskets. For example:

• Assured joint integrity first time – every time

• The gasket forces and seal diameter are

minimal, meaning that the load capacity of the

components is maximised

• The proven reliability of the pressure-energised

bore seal makes Techlok connectors compact

and up to 75% lighter than comparably rated

flanges

• The lack of a conventional flange gasket gives a

gas-tight metal-to-metal seal

CompressionTension Bending

As is well known, external bending forces

are an inevitable part of any piping system,

resulting in high stresses being placed on pipe

joints. Independent strain gauge and

destructive tests have shown the Techlok

connector can withstand considerable bending

moments/forces and axial loading under

pressure without leaking or the bolts

becoming loose, greatly reducing maintenance

costs at the same time as being highly

beneficial to the environment.

NOTES

1. Pressure ratings are intended as a selection guide and assume the following criteria:a. Bore of hub is based upon the sealring boreb. Corrosion allowance is 0.063” for carbon/low alloy steels, zero for stainless steels.c. Hydrotest pressure = 1.5 x pressure rating.

2. Pressure ratings assume AISI 4140 clamps (100 / 75 Ksi, 690/517 MPa) or equivalent.

3. Pressure ratings are calculated on the basis of ASME VIII Div 2 methods and analysis.

4. Pressure ratings to API criteria/materials can be undertaken on request.

5. Combined pressure / external loads / temperature analysis can be undertaken on request.

6. Using the full rated pressure of 316 SS components may result in minor distortions duringHydrotest. If in doubt, contact Vector International for further details.

7. 4130 Hub material assumes 90 Ksi tensile (620 MPa) and 60 Ksi yield (414 MPa).

At the heart of the Techlok connector, there's well provensuccessful sealing technology - the metal-to-metal sealring.

The sealring creates a leak-free connection, unlike flangeswhich leak causing environmental pollution (hydrocarbonemissions), and bring about delays in commissioning andproduction, which in turn has severe cost implications.

The Vector sealring does not leak. It offers weight savings,avoids unscheduled downtime and reduces operationalcosts.

The technology behind the sealring is not limited to Vectorproducts. It can be applied to standard flanges as well asspecial connections for which Vector can design dedicatedsealing solutions.

Vector International’s sealrings have been proven over many years of reliable use

in all conditions and in thousands of applications across a wide range of industries.

Each Vector sealring incorporates three essential principles for a high strength, high

integrity joint:

• Minimum possible seal diameter to reduce pressure separation loads

• Isolated from piping loads

• Pressure energised for enhanced seal integrity

Vector sealrings are completely confined within the connection and cannot be

damaged by bending loads or by overtightening the bolts. All sealrings are available

in a wide range of standard sizes and materials, with special materials to suit special

applications available on request.

Sealring

The Complete Solution

technology

16

Standard Sealrings

The standard sealring has many advantages over conventional gaskets, such as:

• Assured joint integrity first time – every time

• Minimal gasket forces and seal diameter, enabling the load capacity of the

components to be maximised

• Reliable and proven pressure-energised bore seal concept, making the Techlok

Clamp Connector up to 75% lighter than comparably-rated flanges

• Gas-tight metal-to-metal seal

• Reusable

The sealring consists of a central rib section and two seal lips which are tapered to

match the conical seat profile of the hubs. It is these lips which provide the pressure-

energised seal with deformation remaining essentially elastic throughout, and making

the sealring reusable.

The rib acts as a positive stop during make-up, prevents the lips from being

crushed by overtightening, and transfers compressive and bending loads from one

hub to the other.

Coating the sealring with a lubricant such as PTFE prevents the surfaces galling

during make-up and enhances reusability.

The sealring is manufactured from high strength steel compatible with the hub

materials. Typically precipitation-hardening stainless steels, such as grades 630 or 660,

or Alloy 718, are specified for corrosion resistant applications, while low alloy steels

are used for carbon steel pipelines.

Blind Sealrings

• Blind sealrings are an effective way of blanking-off pipe runs, particularly during

construction work-over

• Designed as an auxiliary pressure isolation device and should only be used in

conjunction with other isolation equipment, e.g. valves

• Blinds are marked with a ‘max working pressure’. Check for the suitability for your

application with Vector International

• Smaller sizes can usually take full line pressure

• Available also with Dur-O-Seal option

• Can be provided with indicator flags

• Blind sealrings are not recommended for permanent installation or for cyclic

loading

Strainer Sealrings

• Special Techlok Sealrings, designed and manufactured to the clients own

specification

• During start-up phases, this can be used to protect high value equipment such as

valves, pumps and compressors

• Can be manufactured in any traditional material associated with the Techlok

sealring

19

Dur-O-Seal

• Dur-O-Seal is an alternative sealing mechanism to the standard metal-to-metal

Techlok sealring. It is used to maximum advantage where seats are badly corroded

or damaged, or in sandy conditions on service and vessel closures/pig launchers

• Design ideal where repeated make-breaks are required

• Dur-O-Seal is fully interchangeable with all clamp connectors

• It utilises standard, easily replaceable '0' rings

• Eliminates the need for costly down time for weld repair or on-site machining of

damaged hubs

• It has a zero extrusion gap which allows for high pressure capacity, and ensures no

loss of performance. Note: Dur-O-Seal is not intended for permanent installations

where 'O' ring seals are not to be used due to operating conditions

Orifice Sealrings

• Used in conjunction with Techlok Orifice connectors

• Can be supplied as one piece or two piece assemblies (such as replacement

orifice)

• Can be supplied for flow measurement or as a restriction orifice

• Sizing calculations can be supplied

• Available for all sizes of Techlok sealrings

Transition Sealrings

• Designed to accommodate specification breaks of similar nominal

pipe sizes i.e. 6in 46 matching to 6in 52 would utilise a transition

seal size 46/52

Clamp coatings

Zinc rich, galvanising and epoxy coatings are available for clamp use and applied to recognised industry standards.Procedures and

specifications are available on request. Other specific coatings are available on request.

Test Rings (RIT)Vector has developed a means of testing a Techlok clamp connector joint in-situ

prior to, or in place of a line leak test to save time and ensure seal integrity.

There are two forms of test ring, an independent ring or an integral part of the

sealring.

The separate Reverse Integrity Test Rings (RIT) acts as a sealing carrier which eases

the installation process of the sealring during the assembly by testing the lips of the

sealring the wrong way hence producing a very onerous test on the seal. The

principle is illustrated below.

Materials

The materials used for the separate RIT rings are high strength carbon steel or 630

stainless.

The integral RIT sealrings will complement the base sealring material.

External pressure limits for Techlok sealrings

Tests and calculations indicate the external pressure capacity of standard Techlok

Sealrings (see Graph). The external pressure limit is dictated by the sealring geometry

and is therefore independent of the line pressure.

Two types of testing are shown (i.e. the integral RIT Ring and the independent RIT

Ring), and the pressure limit for both are relatively constant across the sealring range,

22

ReverseIntegrity

23

with the integral RIT Ring having the higher pressure capacity. Consequently a single

test pressure can be used for either type (see Table).

The test is carried out over a 15 minute period. This allows for any settlement of

oil and trapped air in the system. The small test volume means that even the smallest

leak will result in a pressure loss, ensuring a high integrity test.

The RIT test may also be used for gas testing.

Assemblyand disassembly procedure

Assembly Inspect components prior to assembly

Hub and sealring seating surfaces must be clean and free from foreign matter. Damage to hub seatsand seal lips is not acceptable, and should be rectifiedbefore assembly.

LubricateUsually sealrings are coated which acts as lubricant

during make-up. If required light oil or MoS2 spray can beused on hub sealing surface but not on sealring. Take carethat no solid particles are present in the lubricant.

Check sealring stand-offThe sealring should rock slightly against hub face.

Stand-off dimensions given below in inches.

Assemble componentsInstall sealring into the hubs, and assemble clamps

around the hubs. Lubricant applied to the hub/clampcontact area will aid assembly. The studbolts should befitted ensuring that spherically faced nuts locate intospherical seats of the clamps. Lubrication of nut faces andbolt threads is recommended.

Tighten bolts in uniform mannerBolting should be tightened to keep spacing between

clamp halves approximately equal. Clamp segments shouldbe shocked with suitable soft-faced hammer to aid assembly. Always re-tighten bolts after shocking to thetorque/preload values given on facing page.

Align hubsHubs should be aligned so that sealring can be installed

between hubs. DO NOT attempt to correct badly mis-aligned piping by clamping force alone; piping pulling forcesshould only be released when clamp is fully assembled.

Complete Techlok make up requires two conditions.

1) Hubs must be completely face to face with the rib ofthe sealring where standard hubs are used andcompletely face to face with each other where recessedhubs are used.

2) Bolts are made up to the correct torque.

Disassembly De-pressurise the line

Always check, never take it for granted that the line hasbeen de-pressurised. Proceed with caution in case seepagehas caused pressure to build up again.

Slacken nuts but do not remove the nuts from thebolts - then slacken clamp segments

Gradually run the nuts back along the bolts until justloose. If clamp segments remain bound onto hubs, thenBOTH segments must be slackened by hitting the inner faceof the clamp lugs with a suitable soft-faced hammer.

Repeat slackening procedureRe-loosen nuts and re-slacken BOTH clamp

segments until the maximum nut travel shown belowis reached. This should release sealring contact andany residual pressure will then be released through,with the joint.

Check clamps are slack and free to rotateand rock about hubs

Do not proceed until discharge ceases ensure thathubs are apart, sealring is free to move AND clampsare slack, free to rotate or rock.

NOTE - If pressure is still in the line, the sealringmight remain seated, making the join`t tight eventhough it is part dis-assembled. ONLY when allcomponents are loose and clamps are free to move candis-assembly be completed. If the components are notfree to move DO NOT CONTINUE - contact yoursupervisor.

Always ask yourself - what if ?…• What if, the connection is still under pressure, am I or

others in danger, and if so how?• What if, there is still gas or fluid in the line?• What if, the sling snaps?• What if, the load swings in my direction?• What if, the piping springs upon release? (Piping spring may

Notes:1. This is the basic minimum torque/preload value. Use for typically 900lb systems and below, blind closures and Stainless Steel clamps.2. Different friction coefficients will require the torque values to be adjusted. Check with Lubricant manufacturer. 3. Exceeding the stated torque/preload values may cause distortions in the Clamp/Hub. If these torques do not achieve correct make-up (i.e. unable to correct mis-alignment),

then seek assistance as other measures may be needed to assist with the assembly.4. Factor torque by 1.5 for mis-aligned piping and/or 1500lb systems and above. Suitable only for Carbon, Duplex and Low Alloy Steel Clamps with B7 or equivalent bolts.5. Factor torque by 2.0 for extreme mis-aligned piping and/or 2500lb (and 5000psi) systems and above. Suitable only for Low Alloy Steel Clamps with Grade B7 bolts or equivalent.

Training Services

We can offer comprehensive training courses for all relevant personnel at site prior

to their commencing work on the installation/assembly of any Vector product.

Satisfactory completion of the course leads to the award of a competency

certificate.

Site Services

Our Product Support Engineers are available on site at a time when your site

crews are ready to assemble and install piping runs. These engineers will assist in the

identification and repair of potential issues which may ultimately lead to a possible leak

at Hydro-test.

Remember prevention involves less cost than repairs, especially offshore.

Leak Reduction Initiative

We offer and provide a full and comprehensive on site service which delivers all

the benefits associated with both initiatives indicated above, and much more …

Our leak reduction initiative is designed to save you significant time and money

including minimising expensive offshore rework and potential lost production days.

The overall benefits of our leak reduction initiative more than justify the costs.

Vector International supply far more than just pipingproducts. In recent years we have become well known forour Product Support Services and our support for yourproject, no matter how large or small, never ends. Ourintention is for you to have a very successful ‘experience’working with us and our products.

These services are charged to you but in the medium termwill save you time, effort and money and will also preventfrustrations at installation for you and your staff.

It is a well known statistic that a number of mechanicaljoints, e.g. flanges, may show signs of leakage at start up(Hydro-test). With the input of our Product SupportTeams, this risk can be eliminated.
