When welding tubes and pipes such as stainless, duplex, chrome etc., it is important to purge the internal bore with an inert gas to prevent oxidization, discoloration and to ensure a good internal weld profile. Huntingdon Fusion Techniques (HFT) announced it has introduced PurgElite, a range of tube and pipe purging systems to achieve a clean, oxide free, zero color weld. These systems are manufactured to suit pipe diameters from 25-600 mm and are made of low outgassing rate materials, which gives them the ability to produce high quality welds in tubing and piping.
