API 5I Analysis: Performance and application in pipeline engineering API 5L standards and features API 5L pipe properties and applications

At present, pipelines are mainly used in long-distance oil and gas transportation, and the pipe steel pipes used in long-distance pipelines are mainly spiral submerged arc welded steel pipes and straight seam double-sided submerged arc welded steel pipes. Because the spiral submerged arc welded pipe is made of strip steel, the wall thickness is limited, and the improvement of steel grade is limited by the heat treatment of the material. In addition, the spiral submerged arc welding pipe has some insurmountable shortcomings, such as long weld, large residual stress, and poor reliability of the weld. With the increasing demand for oil and gas conveying steel pipes, they are no longer used in densely populated areas and areas with high reliability requirements, and spiral welded pipes are gradually being replaced by straight seam welded pipes.
