Purge with High Flow Rates
PurgExtra Pipe Weld Purge System
Tandem Dam based Tube and Pipe Weld Purging System with PurgExtra® from 2 to 24″ (50 to 600 mm).
These Argweld® PurgExtra® Inflatable Pipe Weld Purging Systems are particularly valuable for the welding of high specification stainless steel, titanium and other reactive alloys.
As one of the best systems devised for pipe weld purging activity, the Argweld® PurgExtra® Inflatable Pipe Weld Purge System are based on a tandem dam system.
Argweld® PurgExtra® Inflatable Pipe Weld Purging Systems are easy to use and provide a very rapid weld purge.
High quality materials used in these Argweld® PurgExtra® Inflatable Pipe Weld Purging Systems guarantee perfect oxide free weld roots in very fast times.
The volume to purge is minimised resulting in significant savings in both time and the quantity of inert gas used.
Argweld® PurgExtra® Pipe Weld Purging Systems have the advantage of additional gas inlets and exhausts to accommodate high flow rates of purging and exhaust gases.
In addition, these systems have no metal parts exposed, making them ideal for use in the food, semi conductor, chemical and pharmaceutical industries to protect internally polished stainless steel tubes, as well as for all other applications where pipe purging systems are required.
Argweld® PurgExtra® Inflatable Pipe Purging Systems can be used over and over again further reducing manufacturing costs.
All systems include RootGlo®, a centring band which glows in the dark for up to 20 hours after 10 minutes exposure to light and IntaCal®, a unique purge gas release system.
