Rapid Purge Inflatable Pipe Weld Purge System

Sizes: 8 to 80" (200 to 2035mm)

Purge larger diameter pipes faster than ever!

Used for stainless, duplex and chrome steels, titanium, nickel and other alloy materials, TAG PIPE Ltd’s Rapid Purge™ 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 discolouration.

A 36” diameter pipe will purge to below 0.1% 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 TAG PIPE Ltds inflatable purging systems, the Rapid Purge™ come with preset 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.


Features and Advantages

Typical purge times of less than 10 minutes

  • The unique “thru-bore” design of the central sleeve minimises the area to be purged, dramatically reducing the volume of gas required.
  • Friction free coatings allow easy movement through pipes from one joint to another, even around bends and elbows.
  • Ready to use, connects to a dedicated and regulated gas supply. Choose any flow rate up to 80l/min. through the twin preset purge valve.
  • A central (glow in the dark) strip allows fast and accurate alignment of the system to the centrepoint of the weld area.
  • The inflatable dams and imbelical hose are covered with a heat resistant material and insulated accordingly for use at temperatures up to 250ºC
