Huntingdon Fusion Techniques (HFT) has developed the HotPurge® pipe purging system for heat-treated chrome and high strength stainless steel pipe joints.
Where the temperatures might be as high as 760ºC (1,400ºF) for many hours, it is important that welders have a suitable system which keeps the welds free from oxidation.
Georgia Gascoyne, CEO for HFT® said, “HotPurge ensures the purge space remains tightly sealed at all times as the inflatable dams maintain an even seal throughout the weld cycle, irrespective of pressure rises or excessive flow rates of argon gas. The large central collar dramatically reduces the space to be purged and makes it easier to reach lower oxygen levels faster than with conventional purging systems.”
