HFT introduces upgraded purging system

08 January 2015

Huntingdon Fusion Techniques, HFT® has released its upgraded Pipe Purging System for High Speed Pipe Joint Welding.

The QuickPurge®III uses the Intacal® II combined with the integrated PurgeGate® device, making it possible to safely inflate the dams with argon gas, prior to releasing it for purging the space between the dams where the weld joint is located. The sleeve between the dams reduces the volume to be purged by two thirds, ensuring a really fast purge time down to 10 parts per million of oxygen.

HFT® has a jointly owned Patent for this design, having originally designed it with the help with Babcock International (now Doosan Babcock) for their contract to lay a stainless steel pipeline along the south coast of England for the transport of Liquid Natural gas from the Isle of Grain.

QuickPurge®III systems are available for each American Pipe Institute (API) Pipe diameter, with an expansion range to cover all internal diameters from Schedule 10 to schedule 160 and the even thicker pipe wall standards.
