Original Press Release:

When the Temperature Rises, Protect Your Weld Purging System with New Heat Resistant Covers

Weld Purging is essential when welding metal tubes and pipes made from stainless steel, titanium and zirconium, in order to achieve non-oxidised, zero colour welds.

Damaging or bursting the inflatable dams on your Tube and Pipe Weld Purging System due to exposure to high temperatures can be a thing of the past now with Argweld® Heat Resistant Covers available from Huntingdon Fusion Techniques HFT®.

Luke Keane, Distributor Support for HFT® said: “As we manufacture the HotPurge® System from 6” upwards, to be used for heated pipework up to 760ºC, we decided to make a much lower cost option for companies who were only concerned about overheating the unprotected dams on our PurgElite® and PurgExtra® Systems.

We have designed Heat Resistant Covers for both our PurgElite® and PurgExtra® Tube and Pipe Weld Purging Systems, with a temperature endurance of up to 300ºC, available from 1 to 24 inches.”

The Heat Resistant Covers are fixed onto the Tube and Pipe Weld Purging System with ties and holes are provided for the PurgElite® and PurgExtra® fittings, such as inlet, exhaust and crimped end. The Covers are usually provided as pairs, although they can be purchased individually in case of damage or loss.

For pipes that need to have the joints and the heat affected zones heat-treated to higher temperatures, HFT® manufactures centre extensions for both the PurgElite® and the PurgExtra® Systems so the bags sit just outside of the heated zone, where the temperature has fallen away, below 300ºC.

HFT® manufactures a complete Family Range of Tube and Pipe Weld Purging Systems, including QuickPurge®, HotPurge®, PurgElite®, PurgExtra® and single Weld Purge Dams, all of which are designed to purge the contaminating gases from the rear of the joint, helping achieve zero colour welds time after time.

Many companies are still fabricating their own home made purging systems made of foam, cardboard, adhesive tape, wood and so on. Like paper, these materials contain a high percentage of water, which is undesirable to have in the presence of a weld. As these poor materials are warmed by the welding operation, they start to outgas, which when combined with the weld pool can cause porosity and oxidation.

HFT®’s Tube and Pipe Weld Purging Systems pay for themselves in the first weld, saving vast amounts of purging time and inert gas costs (Return on Investment Comparisons are available).

Weld purging is the act of removing, from the vicinity of the joint, oxygen, water vapour and any other gases or vapours that might be harmful to a welding joint. Such gases may combine with the metal to form undesirable compounds that may reduce corrosion resistance or may be instrumental in creating cracks or other structural defects in metals.
