API 5L generally refers to line pipe--API 5L line pipe, the line pipe is to transport the oil, steam and water extracted from the ground to the oil and gas industry enterprises through the line pipe. The line pipe includes seamless pipe and welded steel pipe. The ends have flat ends, threaded ends and socket ends; the connection methods are welding, coupling connection, socket connection, etc. With the development of pipeline steel plate technology and the progress of welded pipe forming and welding technology, the application scope 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. It occupies a leading position in the field of line pipes, and the varieties include onshore line pipes and subsea line pipes.
The production of API5L line pipe adopts the 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, such as the limit on carbon equivalent of steel grade line pipe above X80, the production cost of seamless steel pipe is significantly higher than that of welded pipe. Conventional processes are difficult to meet user requirements; all 12Cr1mov alloy pipe manufacturers are carrying out scientific research work to improve the corrosion resistance of their line pipes and to maintain stable performance in low temperature and high temperature environments.
