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 ...

Weld Purging Post Weld Heat Treated (PWHT) Pipework

Welding processes can weaken metals by imparting residual stresses into a material, leading to a reduction in corrosion resistance properties. Post Weld Heat Treatment (PWHT) is regularly used to retain the strength of a metal when welding certain materials including high strength stainless steel a ...

Power Piping Perfectly Purged

Special new high temperature materials allow production problems to be solved. Thanks to the high temperature resistance of glass coated cloth, it is now possible to manufacture Weld Purging Systems to resist temperatures up to 760ºC. This is particularly valuable for welding pipework suitable for ...

Weld Purge your Heat Treated Pipes Confidently with HotPurge®

High strength steel joints must pre-heated prior to welding and also require a post-weld heat treatment. Weld joints of this nature are often purged of oxygen and welded in an inert atmosphere to reduce the risk of ‘sugaring', an imperfection that could allow metal pieces to break off inside pipewor ...
