api 5l PSL2 X56 pipeline steel plate introduction
The production of api 5l PSL2 X56 pipeline steel plate adopts microalloying heating treatment process, the production cost of stainless steel seamless pipe is significantly higher than that of welded pipe, and with the improvement of steel grade, such as the limitation of carbon equivalent of pipeline pipe with steel grade above X80.

In order to improve the anti-corrosion performance of api 5l PSL2 X56 pipeline steel plate and the stable performance in low and high temperature environment, the company has carried out scientific research.
