Heat treatment process

With the development of the pipeline steel plate technology and the progress of welded pipe forming, welding technology, the application range of the pipe with welded pipe in gradually expanding, especially in the large diameter welded pipe class scope the advantage of more wet, and cost factors, welded pipe has been dominant in the field of line pipe, which limits the development of stainless steel seamless steel line pipe.In 2004, the production of seamless pipeline was about 400,000 t, steel grade including x42-70, varieties of onshore pipeline and submarine pipeline.The production of high-steel pipe adopts micro-alloying heating process. 

The production cost of stainless steel seamless pipe is obviously higher than that of welded pipe. And with the improvement of steel grade, such as the limitation of carbon equivalent of steel grade pipe above X80, the conventional process of seamless steel pipe is difficult to meet user requirements.Each 12Cr1moV alloy pipe factory is carrying out scientific research work in order to improve its corrosion resistance and stable performance in low and high temperature environment.In this regard, pansteel group chengdu iron and steel co., ltd. has begun process transformation.

Product Description

Seamless steel pipes are usually made by hot rolling or cold rolling of low alloy structural steels such as 16Mn, 5MnV or 40Cr, 30CrMnSi, 45Mn2, 40MnB, etc., which are high quality carbon-bonded steels such as 10, 20, 30, 35, 45.
