The PPM Rapid Purge System is a high-performance inflatable pipe purging solution designed for large diameter pipe welding applications.
Engineered to achieve extremely low oxygen levels quickly, the system enables high-quality, oxide-free welds while significantly reducing purge time and gas consumption. A 36″ pipe can reach below 0.1% oxygen in under 10 minutes, with smaller pipes purging even faster.
The system is ideal for stainless steel and high-spec alloy welding where speed, consistency and weld quality are critical.
Typical purge time:
The system uses a tandem inflatable dam design connected by an umbilical hose.
Once positioned inside the pipe, the dams are inflated to create a sealed purge zone around the weld. Gas is introduced between the dams, rapidly displacing oxygen and creating an optimal welding environment.
A central luminous strip ensures accurate positioning before inflation.
