RP16 16" Rapid Purge System

Pipe Purge Masters RP16 16" Rapid Purge System is an advanced inflatable purging solution for fast weld purging in pipes up to 16" diameter. It uses a tandem dam system with an umbilical hose containing separate gas and exhaust lines, plus a red strip indicator for centering, to achieve low oxygen levels quickly (typically 5 minutes for 16" pipes), saving time, gas, and money. Ideal for stainless steel, duplex, chrome steels, titanium, nickel, and exotic alloys, it prevents oxidation and discoloration for high-quality welds in fabrication shops, construction sites, and maintenance operations.
