Inflatable Stoppers come in many shapes, sizes and materials

07W-Inflatable StoppersReducing volume or blocking pipes, tanks or other circular orifices for purging, routine maintenance or to prevent the entry of foreign bodies can be much easier with an Inflatable Pipestopper®.

A range of standard and non-standard Inflatable Stoppers for tanks, chambers, tubes, pipes, pipework fabrications and ductwork are available from the Pipestoppers® Division of Huntingdon Fusion Techniques HFT®.

Recently, three extra large Inflatable Stoppers were manufactured for a special project. Georgia Gascoyne, CEO at Huntingdon Fusion Techniques HFT® said: “The two 84” and one 90” were ordered for a project where large diameter pipes inside a turbo generator needed sealing. Within two weeks we were able to manufacture these special Inflatable Stoppers, which helped make the project a success.”

We have the Key to your Perfect Weld

21W PurgEye100 IP65 WeldPurgeMonitorWeld Purge Monitors® are an essential instrument to help obtain non-oxidised, zero colour welds by monitoring the oxygen levels when welding metals such as titanium, stainless, duplex and chrome steels as well as zirconium and nickel alloys where a high quality weld is required.

The Weld Purge Monitor® was invented by Huntingdon Fusion Techniques HFT® in the 1970’s and with over 40 years of innovation, design and manufacturing experience, the company now has a Family Range of PurgEye® Weld Purge Monitors® to measure oxygen levels from atmospheric content (20.94%) down to 10 ppm (0.001%) at which point no discolouration in welds should occur.

By striving for zero colour welds, companies can eliminate the post-weld cleaning costs, which can be very high and in those cases making the cost of each weld ultra significant.

Freeze Sealing for Pipe Repair with Accu-Freeze™

20W-Accu-Freeze-Pipe-Freezing-SystemsContractors and Maintenance Personnel involved in repairing pipework in buildings and other constructions have long been beset with the problem of making repairs on tubes and pipes when they are full of fluid and may not be economically viable to drain.

Now the Accu-Freeze™ Pipe Freezing System is able to freeze a plug in fluid either side of a repair zone, isolating it, to allow work to be carried out without draining the whole system.

Luke Keane, Technical Support at HFT® said: “Accu-Freeze™ utilises liquid nitrogen (LN2) in a controlled way to freeze stationary liquids in a selected section of pipe or tube. By controlling the surface temperature of the pipe or tube, Accu-freeze™ can accurately and safely form an in-line ice plug, capable of withstanding 136 bar in diameters up to 12” (300 mm).”

QuickPurge® Your Pipes for Perfect Welds

QuickPurge Pipe Weld Purge SystemTime is money! Waiting for pipes to be purged ready for welding can take many hours, depending on the diameter of the pipe being welded and the method chosen for purging.

Huntingdon Fusion Techniques HFT® design and manufacture a range of QuickPurge® Inflatable Pipe Purging Systems which reduces waiting times so dramatically that they pay for themselves in less than one weld.

The company was recently tasked with a special project in the USA, where pipes with 90o elbows, up to 54” ø were required to be purged.

Georgia Gascoyne, CEO at HFT® said: “We manufactured QuickPurge® Systems with longer sleeves so that they could easily be pulled around the sharp bends in the pipework.

Flexible Welding Enclosures

Flexible EnclosuresOur Flexible Welding Enclosures® are in use globally and at Shapes Aerospace International they are used everyday for their titanium welding.

The enclosures provide a solution where a rigid chamber may not be economically viable or where space may be at a premium.

They create a purging environment for a fraction of the cost of a rigid chamber for the welding of titanium and zirconium, where the welding zone is required to be purged of oxygen to a level as low as 10 parts per million (ppm).

Flexible Welding Enclosures®, Ideal for the Welding of Titanium and Zirconium

13W-FlexibleWeldingEnclosuresIt is essential when welding critical metallic joints in titanium and zirconium that the welding zone is purged of oxygen to a level as low as 10 parts per million (ppm).

A purging environment for a fraction of the cost of a rigid welding chamber is available for this type of work from Huntingdon Fusion Techniques HFT®.

HFT®’s Flexible Welding Enclosures® provide a solution where a rigid chamber may not be economically viable or where space may be at a premium.

Luke Keane, Technical Support at HFT® said: “For many years the enormous cost of a metal enclosure prevented all but the major companies taking on work involving the fabrication of zirconium and titanium alloys. To the rescue came HFT® a decade or so ago with the introduction of Flexible Welding Enclosures®.”

Size for size, HFT®’s range of Flexible Welding Enclosures® cost considerably less than a metal glove box or vacuum system.

Bright, Clean, High Quality Welds with Trailing Shields®

01W-WeldTrailingShieldsWhen welding titanium, stainless steel and other reactive metal pipework and sheet metalwork, it is important to prevent the welds from oxidising or coming into contact with any air during their welding and cooling periods.

The use of products called Trailing Shields®, designed and manufactured by Huntingdon Fusion Techniques HFT® ensure the weld stays under a protective argon gas coverage, while the hot weld metal is cooling, preventing it from oxidising on contact with air.

Titanium and stainless steels are chosen for their corrosion resistant properties in particular and if they are then allowed to oxidise during the weld cycle, expensive post welding cleaning techniques become necessary.

PurgExtra® Tube and Pipe Purging System

01W-MultiExhaustPipeWeldPurgeSystemInert gas purging is essential when welding metal tubes made from titanium, as well as ultra high purity stainless steel joints and just as important when welding those less critical stainless steel and copper nickel pipe joints, in order to achieve non-oxidised, zero colour welds.

PurgExtra® is the latest weld purging product released by Huntingdon Fusion Techniques HFT® for the purging of tube and pipe joints from 1 – 24” diameter.

This range compliments the PurgElite® series, but in addition has extra purge gas inlets and corresponding exhaust ports.

The PurgExtra® System allows the operator to purge at recommended rates initially and then when it would be an advantage, to introduce additional purge gas to create the desired results.

40 Years in Business Today

40 Years Group HFT signHuntingdon Fusion Techniques HFT® is celebrating 40 years in business and today is the official anniversary date. 

Many people are sending us congratulations, have a look at one of those messages below:

As The Chairman and founder of Orbital Fabrications Ltd it is fair to say that my company would not be here today if it had not been for the support of Ron and Dawn Sewell of Huntingdon Fusion Techniques HFT®. Ron and Dawn were prepared to take a keen and enthusiastic welder, but with little business experience, under their wing and to give him the assistance he needed to make a go of it on his own.

They allowed me to use part of their premises as my workshop and they were happy to share their vast list of contacts to help me win new business and without this support it is quite possible that Orbital Fabrications would not have got off the ground. This indicates to me the level of support Huntingdon Fusion Techniques HFT® are prepared to offer their clients.

Now, 28 years on, Orbital Fabrications Ltd is a successful company in its own right and is delighted to see that Huntingdon Fusion Techniques HFT® is celebrating its 40th year of trading. We know Huntingdon Fusion Techniques Ltd to be a thoroughly professional company and is fully deserved of the success it has seen.

From all at Orbital Fabrications Ltd we congratulate Huntingdon Fusion Techniques HFT® for a fantastic 40 years and we wish you all the very best for the next 40 years.

Ian C Pearson, Chairman, Orbital Fabrications Limited
