Heat resistant purging

Sizes: 3 - 80" (63 - 2,044 mm)(16 to 320 mm)

Systems for the fast Purging of High Temperature Pipework

The PPM Pipe Purge Bag and Rapid Purge Systems are both 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 - 80" (63 - 2,035 mm).

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.
