The Argweld® HotPurge® Heat Resistant Pipe Weld Purging Systems are for use where temperatures might rise to 300ºC (572ºF) and last up to 24 hours.
Available for all pipe diameters from 6 to 88" (152 to 2,235 mm).
These high quality Pipe Weld Purging Systems are ideal for the welding of pre-heat and post-weld heat treated chrome steels such as P11, P22, P91, P92 CMV etc.
Argweld® HotPurge® Heat Resistant Inflatable Pipe Weld Purging Systems come with an innovative central band for easy positioning inside the pipe. This RootGlo® band will gather light prior to placing into the pipe and will glow for many hours of use.
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.
