Inflatable Pipe Weld Purge Systems

Inflatable Bag Pipe Weld Purge System

Range: 2" to 48"

Our Inflatable Pipe Purging Systems are designed to maximise time and minimise cost. Two inflatable bladders are joined by a braided gas hose. Using inert gas (such as argon) to first inflate both bladders on either side of the weld before releasing the gas(via a pre set valve) into the chamber they have created, forcing the oxygen out through exhaust tubes built into the bladders. The Oxygen is removed so the welder can weld the pipes without the risk of oxidisation.

Rapid Purge Inflatable Pipe Weld Purge System

Range: 8" Upwards

The Rapid Pipe Purge systems take gas purging to the next level. The inflatable bladders are housed in heat resistant material, the unique design of these systems means that the area to purge is further reduced, by localising it to the weld root. Whether 8” or 80” pipe, these lightweight, yet rugged systems allow easy withdrawal from the pipe once deflated, even round bends and elbows!

Heat Resistant Inflatable Pipe Weld Purging System

Range: 3" to 80"

The Pipe Purge Bag, Rapid Purge Systems and Inflatable Pipe Stoppers are all available as heat  resistant versions. Designed for use when high temperatures will be encountered during the process of pipe welding; such as pre-heated pipework, and pipes where very high temperatures are required for welding. These versions of our inflatable Pipe purging systems are heat resistant up to 350ºC (572ºF) for up to 24 hours, or up to 500ºC for short periods of time,as with the  standard systems, the heat resistant systems are available for all pipe diameters from 3” to 80” (75 to 2035mm).
