API 5L PSL1 Gr.B steel plate refers to a steel with special requirements, used to transport oil, natural gas and other pipelines. API 5L PSL1 Gr.B steel plate can be produced by hot continuous rolling, steeckel rolling mill or plate rolling mill according to the thickness and subsequent formation, and processed into large diameter steel pipes by spiral welding or UOE straight seam welding.
