Great Barrier for Purging Pipes!

When other purge systems or purge film cannot be used to make a suitable barrier for purging pipes, tubes or fittings, the Argweld® Weld Purge Plugs™ may offer a satisfactory option.

Weld Purge Plugs Orbital Welding Purging Kits

Typical purging applications include:

• Use for small or odd diameter pipes where inflatable purging systems, paper dams or water soluble film may not be available or practical
• Short, complicated, variable size assemblies where purging systems or dams would be too long or do not match the diameters being worked on
• The expanding rubber seal allows the plugs to be used for weld purging oval and out of round tubes as well as in 'elbows', 'tees' and other fittings
• These plugs are also ideal for creating an air-tight seal for leak testing operations

Technical Data and Specification

Weld Purge Plugs Orbital Welding

Leak tightness

The hollow shaft plugs (1.5 to 6") have an "0" ring seal around the stem to ensure leak tightness.

Temperature

The Argweld® nylon Weld Purge Plugs™ can be used up to 75ºC (167ºF) continuously and 105ºC (221ºF) intermittently. With special high temperature seals they can be used continuously up to 120ºC (248ºF).

Increasing use of internal inert gas purging for the process industries and where hygienic stainless steel pipework has called for additional dams which help operators achieve an air tight seal.

The Argweld® Weld Purge Plugs™ offer a useful alternative for small bore pipework.
