HFT-Theme-Welder-PHO-01A

The ability to exploit advances in engineering technology is what drives many world leading companies forwards. Rolls Royce in aero engine production, Siemens in semiconductor development and McLaren in racing car design are all outstanding examples of companies where technical expertise is crucial to their success.

These are all household names of course but there are many much smaller global operations that are able to maintain a leading and international presence through continuous development.

Huntingdon Fusion Techniques, HFT®, in the UK are global leaders in weld purging equipment manufacture.

Their in-house technical expertise is used to research and then integrate advances in materials and components into a range of products that has set quality and performance standards that are recognised worldwide.

Fundamental to HFT®'s success is a team of engineers with decades of experience in the welding industry: a team dedicated to meeting ever-changing demands from consumers for product development.


19W-QuickPurgePipeWeldPurgeSystem

Global standard Argweld® QuickPurge®II,
the first fully integrated Inflatable Weld Purge System.

Available to use with pipes between 300 and 2400 mm diameter

01W-PurgeGateInflatableWeldPurgeSystems

Fitted with PurgeGate® anti-burst device and Intacal®
purposed designed low profile fixed purge valve.

29W-PurgEliteWeldPurgeSystems

Argweld® PurgElite®, at 25 mm the world's smallest weld purge device.
The range covers pipes between 25 and 300 mm diameter.

01W-PurgEye1000Remote-WeldPurgeMonitor
The World's first ever remotely reading Weld Purge Monitor®,
now part of the Argweld® PurgEye® range.

This version allows purge readings down to 10 ppm to be viewed on the monitor,
up to 1 km from the weld zone.


Technical support for customers is provided in many ways one of which is through published articles in International journals. This data is available readily from the company on request but an indication of the depth of source material is provided by the following list of subjects.

These articles cover issues such as weld purging of titanium products, stainless steel tubes and pipes, aerospace components and nuclear industry fabrications. Under development now for publication are features such as weld purging large tanks, remote purging of weld joints in lengthy pipelines, flexible enclosures for weld purging and corrosion issues.
