HFT INFLATABLE PURGE ELITE
Inflatable
Weld Purging System
Purging Systems, Purge Bladders and Purge Dams, using real scientific purge bladder breakthrough technology, Argweld® PurgElite® Inflatable Tube and Pipe Weld Purging Systems introduces to the market place for the first time a 'New' 1 inch (25 mm) System for small diameter tubes and pipes. Another great innovation to help tube and pipe welders save time, money, gas and achieve better welds. The volume to purge is kept small, resulting in savings in both time and cost of inert gas used. Purge bladders and dams suitable for high quality pristine tube and pipe weld purging, 1 to 24" (25 to 610 mm) diameters.

INFORMATION
Argweld® PurgElite® Inflatable Tube and Pipe Purging Systems are available from 1″ to 24″ (25 to 610 mm).
High quality circumferential butt-welding of tubes or pipes with other tubes, pipes or fittings, requires inert gas to be used inside the bore to prevent oxidation and notching of the root penetration weld bead.
The tandem based Argweld® PurgElite® Inflatable Tube and Pipe Weld Purging System has been designed specially for this work.
Each system has 2 protected inflatable dams connected by an armoured heatproof spinal tube.
Once ready to start purging, the system is inserted into the bore with one purge dam either side of the weld joint.
The spinal tube carries the gas to inflate the purge dams and the low profile valve to release the gas gently, to purge the interspace without turbulence.
When the gas connection is made and opened, the purge bladders inflate to form a seal, after which the pressure in the system opens the purge valve.
The inert gas is then fed into the space between the purge bladders expelling the air through the integral exhaust tubes.
Welding can then be carried out with the inert gas ensuring a clean even penetration bead.
Note: Welding will probably be started once the Argweld® PurgEye® Weld Purge Monitor® indicates the required low level of oxygen has been reached.
Afterwards, the purge dams are deflated simply by disconnecting the purge gas feed and the device easily removed. This uniquely designed system means that only one gas connection is required for both dam inflation and weld purging.
An equal number of outlets are provided. Unwanted connections are left closed with the blanking plugs provided.
This range of Argweld® PurgElite® Tube and Pipe Purge Systems are for pipes of nominal diameters from 1″ (25 mm) to 24″ (600 mm).
The connecting spinal tube can be shortened or lengthened to accommodate special requirements.
Frequently Asked
Questions
If you have a question not on our FAQs, please don’t hesitate to get in touch by calling us or filling out the short form below?
Q: Can I use an inflatable purge system in a smaller or larger pipe?
A: In the event that the correct size is not available, adjacent sizes may be usable as there is some crossover in the range of each model. Check the specification sheet.
Q: What is the distance between the inflated dams?
A: The spinal tubes between the dams are of a standard length. A chart is available showing the length for each size of system. They can be manufactured shorter or longer, according to customer requirements.
