QuickPurge® for Weld Purging Large Diameter Pipework


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, 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, which will cost a considerable amount in time and gas costs. With the help of QuickPurge®, large diameter pipes can be purged down to 100 ppm ready for welding in just a short time. The dramatic savings in time and argon pay for the system in just one weld!”

Huntingdon Fusion Techniques, HFT®'s innovative design of the reusable QuickPurge® Systems means that zero colour 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.

Weld Purging with Preheat

In the power generation and nuclear industry, low and medium alloy steels such as SA 213 T91 and SA 335 P91 are chosen for their high strength, but are often prone to cracking during welding. Pre-heating and post-heating reduces the crack sensitivity. In order to meet the requirements of inert gas ...

Thoriated Tungsten Electrodes are left in the dust with MultiStrike®

Red tipped thoriated Tungsten Electrodes are said to contain 1.70% to 2.20% thorium. Thorium improves the quality of Tungsten Electrodes but also has a radio-toxic compound posing a risk to welders, particularly during grinding.
