The HotPurge® for your heat-treated pipes

Huntingdon Fusion Techniques (HFT®) has designed and developed the HotPurge® Pipe Purging Systems, made for heat-treated chrome, and high-strength stainless steel pipe joints, in environments where the temperatures might be as high as 760°C (1,400°F), for many hours.

The HotPurge® systems allow the purge to be safely continued for up to 24 hours while pre-heating, welding, and post-weld heat-treating, with the purge system remaining in place.

HotPurge® includes PurgeGate®, a device that will prevent the over-inflation of, and damage to the inflatable dams. Each HotPurge® also incorporates a central band called RootGlo®, for easy positioning inside the pipe, by lighting up the inside of the pipe for as long as 20 hours with only 10 minutes of previous exposure to daylight.

The HotPurge® Inflatable Pipe Purging Systems can be used repeatedly for weld purging, and will keep the oxygen levels below 100 ppm throughout the welding cycle. This will ensure oxide and coke free welds, without the metallurgical imperfections caused by exposure to too much oxygen.
