Russian steel pipe producer Pipe Metallurgical Company (TMK) announced that its subsidiary Chelyabinsk Pipe Rolling Plant (ChTPZ) and TMK Pipeline Solutions have mastered heat treatment technology for industrial-scale large-diameter (LD) pipelines.
Treated pipes have improved performance characteristics and will be used to lay pipelines of complex designs.
Heat treatment of a pilot batch of 200 tons was successfully carried out at ChTPZ's production sites. This operation reduces the level of residual stress that occurs when forming pipes with diameters of 508 mm and 813 mm, minimizing installation and operational risks and thereby reducing commissioning time for pipes.
The next stage of the project will be the heat treatment of the thick-walled pipes produced by the welding plants using multi-pass welding.
