HotPurge welding device from HFT
20 October 2016
HotPurge® Inflatable Pipe Purging System for welding high strength steel joints, has been developed by international weld purging specialists, Huntingdon Fusion Techniques (HFT), whose US headquarters are located in Florida. HotPurge is designed for use on high strength stainless steel and heat treated chrome pipe joints where the temperatures might be as high as 760ºC (1,400ºF) for many hours.
HotPurge includes PurgeGate®, a device that aims to prevent too much pressure being delivered to the inflatable dams, allowing an increased flow, to achieve a lower oxygen level or faster cooling of the weld zone.
Luke Keane, Distributor Support for HFT said: “HotPurge allows the purge to be safely continued for up to 24 hours whilst pre-heating, welding and post weld heat-treating with the purge system remaining in place. Furthermore, the addition of PurgeGate prevents the risk of dams bursting due to increased pressure.”
