Argweld® HotPurge® Heat Resistant Inflatable Pipe

Purge Your Heat-Treated Pipework Confidently!
The Argweld® HotPurge® Inflatable Pipe Weld Purge Systems are specifically developed for use during pre-heating, welding, and post-weld heat treatment, allowing continuous purging even at temperatures up to 300ºC (572ºF) for up to 24 hours. These systems utilise the latest IntaCal® and PurgeGate® technology to ensure efficient purging and prevent the purge dams from bursting due to over-pressurization. The RootGlo® Centre Alignment Band-aids in accurate positioning.
