Small to Medium Bore Pipe Purge bag System


This Inflatable Pipe Purge System makes an effective seal for purging pipework prior to welding. Once in position the bags inflate forming a tight seal inside the pipe. When inflated the pre-set purge valve will open, releasing inert gas into the weld area.

Professional robust solution for purging of stainless steel, duplex and other alloy pipework resulting in shiny, oxide free weld roots.
