Huntingdon Fusion Techniques HFT® design and manufacture PurgElite®, a range of low cost Tube and Pipe Purging Systems that help to achieve a clean, oxide free, zero color weld in just minutes, available from 1 (25 mm).
Ron Sewell, Chairman for HFT® said: Purging a pipe prior to welding is critical to the success of welding stainless steel, titanium, zirconium and other reactive alloys. PurgElite® systems are simply inserted in the pipe and positioned with the aid of the luminous RootGlo®. When the gas flow is started, the dams inflate, sealing inside the pipe and argon then purges the interspace automatically. A Weld Purge Monitor® connection is standard on each PurgElite®, so the welder can monitor the oxygen content of the purge volume throughout the entire welding process.
Each PurgElite® features IntaCal®, a purge gas feed device, which means there is no complicated valving for the operator to adjust and set. Quick connect/disconnect fittings with collets and O ring seals for gas tight sealing, fitted with anti-release circlips are fitted to all systems to prevent parts accidentally separating inside pipes.
HFT®s innovative PurgeGate® Valve is available as an accessory, a unique one way valve suitable for all types of Inflatable Pipe Weld Purging Systems. PurgeGate® regulates the gas flow and pressure during weld purging to prevent the dams from over inflating and bursting.
Heat Resistant Covers with a rating up to a temperature of 300ºC are available as accessories to protect the inflatable dams. These are attached with ties sewn into the covers.
