Weld Purging CMV Steels

CMV Steels (chromium / molybdenum / vanadium) are widely used for their high temperature creep properties especially in the steam turbine industries. Both pre and post weld heat treatment is necessary to achieve the optimum mechanical strength, but temperatures up to 300ºC (572ºF) must be maintain ...

QuickPurge® Your Large Diameter Pipes for Perfect Welds

Purging large diameter pipework ready for welding can be expensive. Without restricting the volume, there is a high cost involved in inert gas used and time spent waiting for the oxygen level to reach a level low enough for welding to begin.  Weld Purging experts Huntingdon Fusion Techniques HFT® ...

Large Diameter Pipework Fabrications

Large diameter pipework can cause several challenges, especially when those pipes are manufactured from stainless, duplex and chrome steels, titanium or zirconium. When welding such reactive materials, they need to be purged of oxygen before, during and after welding. It is not cost effective to c ...

Keeping Tube and Pipe Joints Clean when Welding

It is important when welding stainless steel and titanium tube and pipe joints to be able to have zero colour, oxide-free welds both on the inside and outside. To achieve the conditions for zero colour, or oxide-free weld joints, it is necessary to remove the air around the joint to a level where ...

Inflatable Pipe Purging Systems for Zero Colour Welds

Producing zero colour tube and pipe welds when joining metals such as stainless, duplex and chrome steels, titanium and zirconium can be challenging and at times can prove costly. In many industries today the welding zone has to be purged of oxygen down as low as 100 ppm, or even lower in industries ...
