Inflatable Bag Pipe Weld Purging System

Range: 2" to 48" (50mm - 1200mm)

Used for 90% of the traditional pipe weld purging applications to provide bright, shiny, oxide free weld roots. The Pipe Purge Bag Systems are quick and easy to use providing a very rapid weld purge. High quality materials are used in the manufacture of these systems guaranteeing perfect oxide-free weld roots in very little time.

Pipe Purge Bag

Due to the design of these systems, the volume of gas used to purge is minimised, resulting in significant savings in both time and the quantity of inert gas used. Return on investment can be achieved in as little as just one or two welds. These robust systems can be used over and over again paying for themselves in very little time.

Features and advantages

  • TAG PIPE Ltd’s Inflatable Pipe Purging Systems dramatically reduce purging times leading to significant savings in labour costs.
    Typical purge times for 4” pipe = 1½ mins; 8” pipe = 4 mins; 12” pipe = 8 mins
  • Ready to use, connects to a dedicated and regulated gas supply. Choose any flow rate up to 20l a min.
  • Through the preset purge valve.
  • Gas pressure control ensures an even positive root bead with no notching.
  • Quick and easy to install simplifying the process of inert gas purging.
  • Heat resistant up to 70ºc continuously.
  • Use less inert gas. The volume of purge gas used is less than 2% of that required for a conventional purge.
