Huntingdon Fusion Techniques has introduced PurgElite®, a range of low cost tube and pipe purging systems to achieve a clean, oxide free, zero colour weld in just minutes.
Ron Sewell, Chairman for HFT said, “To save welders the expense of completely filling tubes and pipes with an inert gas, PurgElite systems are available, manufactured to suit pipe diameters from 1” to 24” (25 to 600 mm). They are designed with a robust inflatable bag on either side of a spinal tube that is used for inflation. They inflate and seal in the pipe, restricting the volume that is needed to be purged, to just 250 mm either side of the weld joint.”
The special spinal tube is resistant to hot metal up to 300oC (572oF) and is super flexible to allow movement of the PurgElite systems around 180o bends if necessary. These spinal tubes are made of a low outgassing rate material, so there is no risk of weld contamination.
