API 5L PSL1 X56 pipeline sheet specification and properties

Standard:API 5L PSL1|PSL2.
Scope:API 5L is generally refers to the standards of pipeline steel, include pipeline pipe and pipeline steel plate.
API 5L line pipe steel grade levels:GR. B, X42, X46 and X52, X56, X60, X70 and X80.
Details

The production of API 5L PSL1 X56 pipeline sheet 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 API 5L PSL1 X56 pipeline sheet, such as the limitation of carbon equivalent of pipeline pipe with steel grade above X80.
