HFT: new heat resistant covers

Published by

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(R) heat resistant covers available from Huntingdon Fusion Techniques HFT(R).

Luke Keane, Distributor Support for HFT said: “As we manufacture the HotPurge(R) system from 6 in. 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(R) and PurgExtra(R) 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 - 24 in.”

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.
