Argon Regulator for Pipe Purging Systems
Dramatic savings can be achieved when welding stainless and chro- mium steels and also titanium alloy tube and pipes with the use of an Inflatable Pipe Purging System.
By restricting weld purging zones, Inflatable Pipe Purging Systems achieve a huge saving in time waiting for pipes to be completely filled with argon, purged down to a low enough oxygen level to start welding safely and also the cost of using a large amount of inert gas.
To avoid such risks and to see that the inert gas being delivered to the pipe purging system is con- trolled, Huntingdon Fusion Tech- niques HFT® have designed and developed PurgeGate®, a unique valve which regulates the pres- sure and flow of gas that is passed through the system, ensuring that it will not burst regardless of the pressure and flow rate.
Ron Sewell, Chairman for HFT® said: “Purging larger diameter pipes has never been easier. Purge- Gate® has found valuable applica- tions in the welding industry where inflatable devices are used for weld purging of tubes and pipes. Setting flow rates and pressures on gas regulators can be interfered with. The pressure inside a purge system can also rise dramatically during a welding sequence, to create a burst. If inflatable devices burst during a tube or pipe weld sequence then the loss of pro- tective gas can result in a highly expensive and extremely incon- venient weld repair.”
PurgeGate® is a low cost, reus- able accessory that has been

designed and constructed to pass a maximum of 7.5 litres/min and 0.5 bar pressure. Other versions of 1 bar and above are also available.
PurgeGate® is fitted as standard on HFT®’s QuickPurge® and Hot- Purge® Tube, Pipe and Pipeline Weld Purging Systems and is an optional extra for their lower cost PurgElite® series. PurgeGate® is designed to fit on all brands of Pipe Purging Systems and the valve can easily be moved from system to
