API pipe production line manufacturers tell you that API pipeline steel pipes belong to the American Petroleum Standard pipeline pipes. The pipeline pipes are used to transport the oil, steam and water pumped out of the ground to the oil and gas industry enterprises through the pipeline pipes. Line pipes include seamless pipes and welded steel pipes, and the pipe ends have flat ends, threaded ends and socket ends; the connection methods are end welding, collar connection, socket connection, etc.

The manufacturer of api pipe production line tells you that with the development of pipeline steel plate technology and the progress of welded pipe forming and welding technology, the application range of welded pipes for pipelines is gradually expanding, especially the advantages of welded pipes in the range of large-diameter group spacing are more obvious, plus Due to the cost factor, welded pipes have occupied a dominant position in the field of line pipes, which limits the development of stainless steel seamless line pipes.
The manufacturer of api pipe production line tells you that the production of high-grade pipeline steel pipe adopts micro-alloying heat treatment process. The production cost of stainless steel seamless pipe is obviously higher than that of welded pipe, and with the increase of steel grade.
