What is the material of API 5L X60
API 5L X60 steel pipe is a kind of steel pipe produced according to the API Spec 5L standard set by the American Petroleum Institute (API). This standard covers a wide range of pipeline steel specifications, in which X60 indicates that the minimum yield strength of the pipe is 413 MPa. This type of pipe is mainly used in oil and gas transmission and other fields, and is widely used in oil and gas transmission systems around the world due to its excellent mechanical properties and reliability.
