QuickPurge® Your Large Diameter Pipes for Perfect Welds

Purging large diameter pipework ready for welding can be expensive. Without restricting the volume, there is a high cost involved in inert gas used and time spent waiting for the oxygen level to reach a level low enough for welding to begin. Weld Purging experts Huntingdon Fusion Techniques HFT® have designed and developed QuickPurge® Systems […]

Weld Purge Monitors - an essential tool for the Process Industry

Weld Purge Monitors ® are an essential tool for the Process Industry, with various models serving different levels of weld purge requirement. There are applications that can be satisfied with Purge Monitors measuring down to 100 ppm when welding stainless steel for example, however for higher specification industries such as the Aerospace, Food and Drinks, […]

Secondary Inert Shielding Gas Application with Argweld Weld Trailing Shields®

A secondary inert shielding gas application is often required when welding reactive metals such as titanium alloys and stainless steels, to protect the weld from oxidation until it has cooled to a safe temperature. The low cost Argweld Weld Trailing Shield® provides additional inert gas coverage during welding and is available from Huntingdon Fusion Techniques […]

Safe Pipe Repair with Accu-Freeze™

Pipe freezing for temporary pipe isolation has now become the safest, quickest and most cost-effective method for pipeline leak testing, maintenance work or for making pipe repairs including valve and other control system replacements. It is still very common for maintenance workers to drain down entire systems before repairs can be made but this can […]

Welding Chambers for welding under an inert gas coverage

Welding Chambers make it possible to weld stainless steels, titanium and other reactive alloys effectively without oxidation and discolouration. The ever-increasing demand in the Aerospace, Medical Scientific and Nuclear Industries for high-quality welded components has forced new technology for reactive metals such as titanium to be welded in a complete inert gas coverage. Flexible Welding […]

Pressure Testing Pipework up to 6 Psi with Inflatable Stoppers

Vessels such as pipelines, gas cylinders and fuel tanks are often pressure tested for strength and leaks. A range of standard and non-standard Inflatable Stoppers for tanks, chambers, tubes, pipes, pipework fabrications and ductwork is available from the Pipestoppers® Division of Huntingdon Fusion Techniques HFT®. Ron Sewell, Chairman for HFT® said: “Our range of Inflatable […]

QuickPurge Inflatable Pipe and Pipeline Weld Purging System

QuickPurge The World’s Largest Inflatable Pipe Purging System

QuickPurge Pipe and Pipeline Weld Purging Systems are manufactured up to 88” Diameter (2’235 mm). Filling and purging large pipe diameters ready for welding with an inert gas is very costly. Not only is a lot of time spent waiting, but also a large volume of gas is required. Weld Purging Experts Huntingdon Fusion Techniques […]

Low Cost Weld Purge Monitor for Welding Titanium

Weld Purging Techniques are now used in most industries especially when welding reactive metals. Whilst the welding torch provides a protective cover to the top of the fusion zone, inert gas coverage is also required at the weld root. By sampling the gas and testing the oxygen content around the weld, the welder knows when […]

No Burst Pipe Purging Systems with PurgeGate

Pipe welders are now turning more and more to Inflatable Pipe Purging Systems because of their easy use to complete a weld faster and with less risk of oxidation, to save money from the speed and the avoidance of reject or cut outs. These unique systems restrict weld purging zones, saving time waiting for pipes […]

High Quality Feed Hose for Inert Gas Supply

Using a high quality gas welding hose will ensure a leak tight method of feeding non-contaminated gas into the welding zone for weld purging. Continuing their pursuit to advance in Weld Purging Technology, Huntingdon Fusion Techniques HFT® now manufacture tailor made Inert Gas Feed Hose assemblies with leak tight fittings and a low outgassing rate. […]

Welding Titanium: Tips for Success

Welding Titanium: Techniques for success! Welding Titanium: Titanium is a reactive metal. When it is heated during welding it will react with oxygen that surrounds it, forming oxidised welds, which will lead to loss of corrosion resistance properties. In many industries today, this is no longer acceptable. Oxidised welds will be rejected, causing unnecessary rework. […]

Portable 10 ppm Weld Purge Monitor

With ever-improving standards in Quality Control, measuring the oxygen level around welds before, during and after welding reactive metals is crucial. The hand held PurgEye® 200 is a Weld Purging Monitor® specifically developed and designed for use when welding titanium, zirconium, high specification stainless steel and nickel alloy joints, so that the user can produce […]
