HFT introduces PurgExtra tube

Inert gas purging is vital 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-oxidized, zero color welds.


PurgExtra™ is the latest weld purging product released by Huntingdon Fusion Techniques HFT® for the purging of tube and pipe joints from 1 to 24” diameter. This range compliments the PurgElite® series, but in addition has extra purge gas inlets and corresponding exhaust ports. The 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.

PurgExtra™ has two inflatable dams connected by a heat resistant, highly flexible gas hose that has the unique IntaCal® gas release system integrated. IntaCal® allows the dams to be inflated correctly and then releases the inert gas to safely purge the space between the dams. As an option, the PurgeGate® accessory may be fitted to the PurgExtra™ Systems to protect the inflatable dams from accidental or faulty opening of gas supply valves giving protection to the dams against bursting.
