Usual quenching and tempering heat treatment process at room temperature the tubing is heated to above the phase transition point and heat for some time, it austenitizing and then rapid cooling (water or oil cooling) to room temperature to obtain the martensite required, after the high-temperature tempering 600 ~ 650 ℃ and holding time to achieve a more stable tempered sorbite tissue, so that the pipe has good mechanical properties.

Key technical issues quenching process is to ensure that the steel pipe before quenching temperature, and water quenching process cooling and water quenching effect. Tianjin Seamless Steel Tube Plant binding mode of the production process, from the tube into the pipe rolling the whole deformation process is always in the metal structure fully austenitic state finished, and the finishing temperatures are kept above the phase transition point, this can be directly quenched, obtaining martensite. This use of waste heat pipe sizing after quenching the way, is theoretically feasible.
