Single Inflatable Weld Purge Dam

Single Ended Dams for closing welds where retrieval is possible and other joints where a Tandem Pipe Purging System is not required.

Ideal for tight bends, T piece joints, dome end connections and so on, where an old fashioned Tandem Weld Purge Bladder Inflatable System or a modern Argweld® Pipe Purging System cannot be used.
This range of low cost, single ended Inflatable Weld Purge Dams is an innovative product, manufactured and designed by Huntingdon Fusion Techniques HFT®. These Inflatable Weld Purge Dams provide an excellent grip in the pipe with an effective all-round seal.

Each Dam has a weld purge gas inflation hose, an exhaust port for exiting purge gas and a hose for extra gas input for higher speed purging, for weld cooling to reach interpass temperature specifications and for the assurance of obtaining a zero colour (non oxidised) weld. There is also an additional hose for a Weld Purge Monitor® to be attached. Quick, fast, very simple to use use.

Argweld® is a recognised trademark in the industry and our family range of products is here to help you achieve that better weld and save money at the same time.
