GBC 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 20 Ltr/min. The bags inflate, a seal is created either side of the weld joint and the pressure valve releases gas into the weld chamber. 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 and commence welding. The system is left in position post welding 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drops to below oxidation levels, then the purge gas feed is disconnected, the bags deflate and the system can be withdrawn.
