Weld purging is essential when welding metal tubes and pipes made from stainless steel, titanium, chrome and nickel steels, where a high strength joint or a clean and smooth joint is needed. Huntingdon Fusion Techniques (HFT®), whose US headquarters are located in Florida, provide an extra gas purge for weld purging tube and pipe joints of 1 – 24 in. dia. with its PurgExtra® inflatable tube and pipe purging systems.
PurgExtra comprises of two inflatable dams that are connected by a heat resistant, flexible gas hose that has the IntaCal® gas release system. IntaCal allows the dams to be inflated correctly before releasing the inert gas to safely purge the space between the dams. The IntaCal valve aims to replace bulky complicated valves.
