Technical Data and Specification
The Argweld® HotPurge® Heat Resistant Inflatable Pipe Weld Purging System comprises a tandem inflatable dam system connected by a volume reducing collar.
Available for all pipe diameters from 6 to 88" (152 to 2,235 mm).
A gas system IntaCal® eliminates old fashioned valves and provides a more accurate and controlled purge gas release.
The inflatable dams and umbilical hose are covered with a heat resistant material and insulated accordingly for use in pipework where the temperatures may rise as high as 300ºC (572ºF) for 24 hours or more.
Each system incorporates RootGlo®, a band around the centre for positioning purposes which will glow up to 12 hours inside the pipe.
PurgeGate® is the most revoluntionary device on these systems which provides pressure and flow control as well as a guarantee against bursting due to over pressurisation.
Multiple sintered outlets disperse weld purge gas evenly without turbulence.
