The PipeÂ PurgeÂ Bag and RapidÂ PurgeÂ Systems are both available asÂ heat resistantÂ versions. Designed for use when high temperatures will be encountered during the process of pipeÂ welding; such as pre-heated pipework, and pipes where very high temperatures are required forÂ welding.
Designed for use when high temperatures will beÂ encountered during the process of pipe welding;Â such as pre-heated pipework, and pipes whereÂ very high temperatures are required for welding.
These versions of our inflatable Pipe purgingÂ systems are heat resistant up to 350ÃÂºC (572ÃÂºF) forÂ up to 24 hours, or up to 500ÃÂºC for short periods ofÂ time, as with the standard systems, the heat resistantÂ systems are available for all pipe diameters from 3 to 80" (75 to 2035mm).
Mirroring the features of the standard range of inflatable purging systems, the heat resistant range comes with a central band for rapid centering of the system to the weld root for the fastest set up times.
The welder can position these systems prior to pre-heating and leave them in place throughout the pre-heating, welding and post-heat treatment cycles, allowing the weld to be purged continuously for up to 24 hours if necessary.Â
