Low cost pipe weld purging system (for purging hot sections)

4" PurgElite® Pipe Weld Purging System with a 2.4 meter long hose

When welding pipes and tubes that need to go through high temperature thermal cycles before, during and after welding, it is usually important to purge the insides with an inert gas, to prevent oxidation and scaling and to ensure a good internal weld profile.

In many cases there is very little room to manoeuvre weld purging systems so that they are protected from the high temperatures associated with the pre--and post-weld heating processes and the operators have to purchase the more sophisticated heat protected systems such as the HFT® HotPurge™ models.

However, in some cases, there can be sufficient length in the tube or pipe structure, that a normal Weld Purging System can be used.

Huntingdon Fusion Techniques Ltd has been able to use its development team to manufacture a variety of different Weld Purging Systems for such tubes and pipes, where the the inflatable dams can be kept outside of the heated areas.

Special high temperature resistant gas hose material, ensures that the purge dams stay inflated, firmly sealing the purged void to protect the weld throughout the whole thermal and welding cycles.

The picture shows a 4" PurgElite® Pipe Weld Purging System with a 2.4 meter long hose fitted with IntaCal® low profile purge valve technology and the PurgeGate® device that guarantees that the inflatable dams cannot burst due to overinflation.

The PurgElite® range is available from 1 24" diameter and the associated QuickPurge®II range for diameters from 5" up to 96".
