Purge larger diameter pipes faster than ever!
Used for Stainless, duplex, chrome steels, titanium, nickel, and other alloy materials, the PPM Pipe Purge Bag System™ systems enable high-speed welding of larger diameter pipe joints that have to be purged. Designed to enable the user to produce high quality, reliable and repeatable welding of stainless steel tube and pipe joints to ensure a very fast weld purge time and a very high-quality weld root, free from oxidation and discoloration. A 36in diameter pipe will purge to below 0.1percent oxygen in less than 10 minutes and all smaller pipes correspondingly faster. Dramatic savings of time, gas, and money can be made by using these systems. Due to the quality of the materials used, the Rapid Purge™ systems can be used over and over again further reducing manufacturing costs. As with all of the PPM Pipe Purge Bag System inflatable purging systems, the Rapid Purge comes with pre-set valves, so are ready to use ‘straight out of the box’. Rapid Purge™ has been developed specifically to enable high speed purging for any pipe welding application.
How it works
The Rapid Purge Inflatable Pipe Purging Systems for pipe and vessel purging comprises a tandem inflatable dam system connected by an umbilical hose and collar to reduce the volume being purged. A gas exhaust valve is installed between the primary and secondary dam, along with an auxiliary argon purge line.
Each Rapid Purge System is covered with heat-protective material so that the higher temperatures closer to the weld do not damage the system. The robust design of the Rapid Purge Inflatable Pipe Weld Purging Systems allows for many years of repeatable trouble-free use.
