Twin Bag Purging Systems consist of two inflatable bags connected by a spinal tube and a pressure valve. The system is positioned by viewing the luminous tape through the weld joint gap. E-Z ZONE TAPE is used to seal the weld gap and purge gas flow can commence at up to 10 Ltr/min.

The bags inflate and a seal is created on either side of the weld joint. The pressure valve then releases gas into the weld chamber and the purging process commences.  By using a GBC Oxygen Monitor to constantly measure the oxygen content in the weld chamber the welder will know when to reduce the gas flow to c. 5 Ltr/min and commence welding.

The system is left in position post-welding with gas flowing until the weld joint temperature drops to below oxidation levels, then the purge gas feed is disconnected, the bags deflate, and the system can be withdrawn.
