Heat Treatment of Seamless Pipe

Heat treatment of seamless pipe is to impose different heating, insulation and cooling system in the solid range by changing the organizational structure of the steel surface or inside in order to obtain the desired properties of an integrated thermal processing. Because the performance of the steel structure is made of steel decision. Heat treatment has been able to change the properties of steel, is by changing the organizational structure of the steel to achieve. The main purpose is to change the properties of heat-treated steel that improve process performance steel (steel, cold and hot process demonstrated performance) and improve performance steel (steel manifested in the conditions of service performance). 

Types of heat treatment process: Depending on the heating and cooling methods, usually divided into the following categories: 
(1) ordinary heat treatment. Including annealing, normalizing, quenching and tempering. 
(2) surface heat treatment. Including surface hardening (induction heating surface hardening, flame heating surface hardening and other surface heating quenching) and chemical treatment (carburizing, nitriding, carbonitriding, etc.). 
(3) Other heat treatment. Including controlled atmosphere heat treatment and deformation and heat treatment.
