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.
