UK-based weld purging innovator, Huntingdon Fusion Techniques (HFT®), has released another weld purging product, this time to purge tube and pipe joints ranging from 1-24 inches in diameter.
The PurgExtra® series for tube and pipe purging has been designed to complement its previous PurgElite® range, but has added purge gas inlets and corresponding exhaust ports. The new device allows extra argon (Ar) gas to flow into the welding zone for cooling purposes and its flexible spinal hose between the dams allows it to be pushed or pulled easily around bends.
The instrument is comprised of two inflatable dams connected by the heat resistant gas hose, which contains the IntaCal® gas release system. This system allows the dams to be inflated correctly and then releases excess inert gas to safely purge the welding space.
Additionally, the centre of the spinal hose contains a strip of RootGlo® material, which illuminates the inside of the pipe and allows the user to see when the PurgExtra System has reached the correct position for operation.
