Power Piping Perfectly Purged

Special new high temperature materials allow production problems to be solved. Thanks to the high temperature resistance of glass coated cloth, it is now possible to manufacture Weld Purging Systems to resist temperatures up to 760ºC. This is particularly valuable for welding pipework suitable for power stations and other utilities that produce high pressure steam […]

Low Cost 1 PPM Weld Purge Monitor®

For many years, oxygen monitors and gas analysers have been used for weld purging. These instruments have been designed and calibrated for accuracy at atmospheric oxygen level, but not for weld purging where accuracy is required when reading much lower oxygen levels. With their scientific background, Huntingdon Fusion Techniques HFT® have designed and manufactured the […]

Double Freezing technique for large diameter Valve replacement

Replacing valves in a pipeline can be a challenge, especially when the pipelines have liquids running through them. One option is to completely drain the system to make the repairs, which can prove costly with respect to loss of expensive fluid, heating or cooling costs, security matters, time that system is down plus labour costs. […]

Inflatable Stoppers for Petrochemical Applications

Blocking pipes or other orifices to carry out routine maintenance and other applications can prove challenging where hydrocarbons are present in liquid and gas form. Now, a range of hydrocarbon resistant Inflatable Pipestoppers is available for the Petrochemical and Oil and Gas Industries. Manufactured in cylindrical and spherical formats from 1 – 44” (25 – […]

Highest Quality Welds made with Lower Costs

Welding stainless steel, titanium, zirconium, niobium and other metals sensitive to atmospheric gases, requires oxygen levels to be as low as 10 ppm and in some cases, knowledge of dew point level in the shielding and purging gas. Many welds of this nature are still welded with archaic or home-made items to try to shield […]

Handy Purge Monitor, now with PurgeNet™

To remain at the forefront of Weld Purging technology, World leading Weld Purging Experts and inventors of the Weld Purge Monitor®, Huntingdon Fusion Techniques HFT® have launched the updated hand-held PurgEye® 200 Weld Purge Monitor®, now with PurgeNet™. When welding metals such as stainless steel and titanium, it is essential to measure the oxygen level […]

Keeping Tube and Pipe Joints Clean when Welding

It is important when welding stainless steel and titanium tube and pipe joints to be able to have zero colour, oxide-free welds both on the inside and outside. To achieve the conditions for zero colour, or oxide-free weld joints, it is necessary to remove the air around the joint to a level where the oxygen […]

Low Cost one-way Valve for specific flow rate and pressure

This low cost accessory has been designed and constructed to pass a maximum of 7.5 litres/min and 0.5 bar pressure. Other versions of 1bar and above are also available. Designated “PurgeGate®”, this nifty, hi-tech item has applications in both fluid and gas control. Its small size and low weight makes it valuable for small liquid […]

Remote Monitoring of Weld Purge up to 1 km away

When welding lengths of tube and pipework fabrications, as well as sections of pipelines of 20 metres length and more, one problem operators face is not receiving a fast and true weld purge reading from the purge zone. Now, for the first time, Huntingdon Fusion Techniques HFT® makes it possible to have an immediate reading […]

New Tungsten Electrode Grinder

Ensuring your Tungsten Electrode is sharpened correctly can help to improve weld quality. Tungsten Electrode Grinders are a convenient, safer and accurate way than other methods of grinding Tungsten Electrodes. Back by popular demand, Huntingdon Fusion Techniques HFT® have re-initiated the manufacturing of the TEG-2 Tungsten Electrode Grinder, which retired from their product range a […]

Introducing PurgeNet™ and Accessories

Monitoring the oxygen level before, during and after welding is essential. Welding in an environment of less then 100 ppm for stainless steel and less than 20 ppm for titanium ensures that welds are free from oxidation. Allowing joints to oxidise when welding then involves mechanical or chemical oxide removal to prevent to loss of […]

Weld Purging for Closing Welds

Weld Purging a variety of pipes of different diameters can prove complex and costly, particularly when having to fill whole pipework systems with expensive argon gas. One solution that welders have traditionally devised has been to construct homemade foam or paper dams that are placed either side of the weld, constricting the purge volume to […]
