Weld Purging large diameter pipework made from stainless, duplex and chrome steels, titanium or zirconium can be expensive, with requirements to have the oxygen level well below 100 ppm during the welding cycle. As it is not cost effective to completely fill pipework with expensive inert gas, global leader Huntingdon Fusion Techniques HFT® have developed QuickPurge® Systems to dramatically reduce the space that needs to be purged.
Ron Sewell, Chairman for HFT® said, Welders can often spend up to half a day purging pipes. With the help of QuickPurge®, large diameter pipes can be purged down to 100 ppm, ready for welding in just a short time.
HFT®s innovative design of the reusable QuickPurge® Systems means that zero color welds will be achieved and there will be no loss of corrosion resistance caused by oxidation.
QuickPurge® has an additional gas input line, which means extra purge gas can be introduced for applications such as this, thereby achieving a much faster purge, down to the lowest oxygen levels, which is perfect for larger diameter pipes where quality welds are required.
All systems are manufactured as standard with a hose for connecting a Weld Purge Monitor® to, which can read oxygen levels down to as low as 10 ppm depending on the model. For pre-heated chrome steel and high strength stainless steel pipe joints, HFT® design and manufactures the HotPurge® range for a higher and longer temperature exposure.
