Quenching was Ms point temperature of the steel above the appropriate speed to slow cold cold Ms point or less, achieve superior organizational performance. Need to quench quenching medium, a common cooling medium is quenching oil, water-soluble quenching agent, water and saline and alkaline

Welded pipe has welded joints rigid, multi-layer welding, welding metal bulky, so welded joints in high-stress state, such as the weld metal has a higher yield point, it is difficult to relaxation through its plastic deformation of welded joints of high stress
