COB Helps Develop Revolutionary Pipe Purging Technology PurgeGate Valve

November, 2013—COB Industries introduced revolutionary new PurgeGate technology which is certain to be a game-changer in the world of pipe purging. Tandem inflatable pipe purging systems have proven to be the fastest, most effective method of pipe purging when welding stainless steel, chrome, titanium and other materials that require an oxygen free weld, but the potential risk of bursting the dams due to over-inflation has always been an issue…until now.

COB Industries, working together with Huntingdon Fusion Techniques of the U.K. has introduced PurgeGate valves which are proprietary devices that function like an in-line regulator or pressure reducer that prevents the bladders from over-inflating no matter what pressure or flow rate is used. ANY other type of inflatable purge dam can be ruined if the gas flow / pressure is turned up too high or if the purge valves are not set or maintained properly. The new Argweld® QuickPurge® II systems with PurgeGate are the ONLY true plug-and-play purge system with no valves to adjust or maintain, and no risk of bursting bladders due to over-inflation.

The benefits of inflatable purge dams (faster purge times, less gas consumption, etc.) have been well established and now those benefits can be utilized with a longer lasting, more durable system. To see how quickly these systems pay for themselves (ROI) click here.
