Bright, Shiny, Oxide-Free Welds with PurgExtra®

Tubes and pipes made from titanium, stainless steel, chrome/nickel steels are mostly required to be welded in a non-oxidised environment in order to achieve a metallurgically correct, zero colour weld. Best results are obtained by reducing the volume to be purged, with an inflatable Weld Purging System. Leading the way in Weld Purging Technology, Huntingdon Fusion Techniques HFT® have developed...

Faster Pipe Purging with QuickPurge®

When stainless steel, duplex steels or titanium pipes need to be welded in the process industries, they generally have to be purged of air and water vapour, in order to obtain the quality of weld demanded by such industries. Even today, more than 40 years after high quality pipe weld systems were developed, welders are still carving crude discs out of sponge foam without understanding the...

Weld Purge Your Heat Treated Pipes Confidently with HotPurge®

High strength steel joints must pre-heated prior to welding and also require a post-weld heat treatment. Weld joints of this nature are often purged of oxygen and welded in an inert atmosphere to reduce the risk of ‘sugaring’, an imperfection that could allow metal pieces to break off inside pipework and cause damage to turbines, for example. With the high temperatures and length of time at...

QuickPurge® Your Pipes for Perfect Welds

Time is money. Welders, supervisors, welding engineers, quality control personnel and others are kept waiting, sometimes for many hours, for stainless steel or titanium pipe joints to be purged of oxygen ready for welding. Weld purging is necessary to reduce the oxygen content below 50 parts per million so that the weld surfaces and the adjacent hot metal doesn’t oxidise and thereby cause loss...
