Techlok Clamp Connector
Clamp Connector
A four-bolt pipe connector typically weighing 75% less than a comparable standard ANSI or API flange
Hibernia topside platform Atlantic Canada
Techlok Clamp Connector A radially-bolted mechanical pipe connection which allows quick make-up and break-out and is ideal where space, weight and joint integrity are 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.
The Techlok advantage
Prior to Assembly
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
Self Energised Seal
the first-stage self-energising seal. The applied bolting loads are transmitted to the clamps through almost 360º contact
Fully Assembled
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. Pressure Energised Seal
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 3

Clamps
Techlok Components
The two Techlok clamp segments make
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
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.
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.
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
Techlok's sealring has many advantages
sealring. Techlok’s sealring has a central rib
over conventional gaskets. For example:
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
• 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
API Fire Testing It is important to analyse product performance correctly when specifying pipe connectors. Extensive testing has shown the Techlok range of clamp connectors will suit most applications. Successful strain gauge testing under full load conditions, fire testing to API 6FB parts 1 and 2, independent testing and witnessing resulting in Bureau Veritas Type Approval, and extensive Finite Element Analysis during the fire test programme, make Techlok today the most comprehensively tested clamp connector available
Type Approval Testing The Techlok range of connectors has been subjected to extensive strain gauge and destructive testing under independent conditions both in-house and at recognised test centres, and, after combined pressure and external load type testing, carries Type Approval by Bureau Veritas.

Techlok Size Code
NOTES 1. Pressure ratings are intended as a selection guide and assume the following criteria: a. Bore of hub is based upon the sealring bore b. Corrosion allowance is 0.063” for carbon/low alloy steels, zero for stainless steels. c. Hydrotest pressure = 1.5 x pressure rating.
4. Pressure ratings to API criteria/materials can be undertaken on request. 5. Combined pressure / external loads / temperature analysis can be undertaken on request.
2. Pressure ratings assume AISI 4140 clamps (100 / 75 Ksi, 690/517 MPa) or equivalent.
6. Using the full rated pressure of 316 SS components may result in minor distortions during Hydrotest. If in doubt, contact Vector International for further details.
3. Pressure ratings are calculated on the basis of ASME VIII Div 2 methods and analysis.
7. 4130 Hub material assumes 90 Ksi tensile (620 MPa) and 60 Ksi yield (414 MPa).
15
Sealring technology At the heart of the Techlok connector, there's well proven successful sealing technology - the metal-to-metal sealring. The sealring creates a leak-free connection, unlike flanges which leak causing environmental pollution (hydrocarbon emissions), and bring about delays in commissioning and production, which in turn has severe cost implications. The Vector sealring does not leak. It offers weight savings, avoids unscheduled downtime and reduces operational costs. The technology behind the sealring is not limited to Vector products. It can be applied to standard flanges as well as special connections for which Vector can design dedicated sealing solutions.
The Complete Solution 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.
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 pressureenergised 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.
17
Sealring technology 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
18
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
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

Reverse Integrity 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

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.

EasiLift Lifting Frame EasiLift, by Vector International has been designed as the optimum solution to the continuous challenge of manoeuvring Techlok blind hubs and clamps, safely and easily (with health and safety in mind). EasiLift enables safe assembly and disassembly of blind hub connections. It is also capable of safely retaining the sealring during assembly. There are a minimised number of moving and removable parts to aid reliability and the frame itself is a rigid, welded structure, tested and certified to comply with LOLER and PUWER regulations. This system does not in any way replace any part of the existing assembly and disassembly procedures for Techlok and is meant to be used only as a blind/clamp handling system. Easilift
• Creates safe manoeuvring of blind hubs and clamps offshore • Enables quick and easy lifting, assembly and disassembly of connectors • Sealring is retained in place during assembly • Minimises overall downtime, saving time and money
27
Assembly and disassembly procedure Assembly
Disassembly
Inspect components prior to assembly Hub and sealring seating surfaces must be clean and free from foreign matter. Damage to hub seats and seal lips is not acceptable, and should be rectified before assembly.
De-pressurise the line Always check, never take it for granted that the line has been de-pressurised. Proceed with caution in case seepage has caused pressure to build up again.
Lubricate Usually sealrings are coated which acts as lubricant during make-up. If required light oil or MoS2 spray can be used on hub sealing surface but not on sealring. Take care that no solid particles are present in the lubricant.
Slacken nuts but do not remove the nuts from the bolts - then slacken clamp segments Gradually run the nuts back along the bolts until just loose. If clamp segments remain bound onto hubs, then BOTH segments must be slackened by hitting the inner face of the clamp lugs with a suitable soft-faced hammer.
Check sealring stand-off The sealring should rock slightly against hub face. Stand-off dimensions given below in inches. Assemble components Install sealring into the hubs, and assemble clamps around the hubs. Lubricant applied to the hub/clamp contact area will aid assembly. The studbolts should be fitted ensuring that spherically faced nuts locate into spherical seats of the clamps. Lubrication of nut faces and bolt threads is recommended. Tighten bolts in uniform manner Bolting should be tightened to keep spacing between clamp halves approximately equal. Clamp segments should be shocked with suitable soft-faced hammer to aid assembly. Always re-tighten bolts after shocking to the torque/preload values given on facing page. Align hubs Hubs should be aligned so that sealring can be installed between hubs. DO NOT attempt to correct badly misaligned piping by clamping force alone; piping pulling forces should 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 of the sealring where standard hubs are used and completely face to face with each other where recessed hubs are used. 2) Bolts are made up to the correct torque. 28
Repeat slackening procedure Re-loosen nuts and re-slacken BOTH clamp segments until the maximum nut travel shown below is reached. This should release sealring contact and any residual pressure will then be released through, with the joint. Check clamps are slack and free to rotate and rock about hubs Do not proceed until discharge ceases ensure that hubs are apart, sealring is free to move AND clamps are slack, free to rotate or rock. NOTE - If pressure is still in the line, the sealring might remain seated, making the join`t tight even though it is part dis-assembled. ONLY when all components are loose and clamps are free to move can dis-assembly be completed. If the components are not free to move DO NOT CONTINUE - contact your supervisor. 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 also prevent free rotation of clamps around the hubs).

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.

Techlok in the field Vector International supply far more than just piping products. In recent years we have become well known for our Product Support Services and our support for your project, no matter how large or small, never ends. Our intention 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 term will save you time, effort and money and will also prevent frustrations at installation for you and your staff. It is a well known statistic that a number of mechanical joints, e.g. flanges, may show signs of leakage at start up (Hydro-test). With the input of our Product Support Teams, this risk can be eliminated. 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. Typical damage caused through mis-handling 30
The overall benefits of our leak reduction initiative more than justify the costs.
