Application Area

Steel pipe seam heat treatment

Weld seam online annealing is an advanced process for the production of high-grade steel pipes. The steel pipe weld seam is heated above the critical temperature, and then annealed to eliminate welding residual stress and improve the microstructure, so that the weld seam and its heat affected zone have the same microstructure, toughness, and strength properties as the base material.

Heat treatment of metal pipes

Steel pipe/stainless steel pipe/non-ferrous metal pipe annealing, quenching, tempering, solution and other heat treatment applications.
