API 5L generally refers to pipeline pipe - API 5L pipeline pipe, which transports the oil, steam and water extracted from the ground to oil and gas industrial enterprises through pipeline pipe. Pipeline pipe includes seamless pipe and welded steel pipe, and its pipe end has flat end, threaded end and socket end; 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 pipe for pipeline is gradually expanding, especially in the range of large diameter group spacing, the advantages of welded pipe are more bright and wet. Coupled with the factor of cost, welded pipe has occupied a leading position in the field of pipeline pipe, which limits the development of stainless steel seamless pipeline pipe. In 2004, the output of seamless pipeline pipe was about 400000 T, and the steel grade included x42-70, including onshore pipeline pipe and submarine pipeline pipe.
The production of API5L pipeline pipe adopts micro alloying heating treatment process, and the production cost of stainless steel seamless pipe is significantly higher than that of welded pipe. Moreover, with the improvement of steel grade, such as the limitation of carbon equivalent of steel grade pipeline pipe above X80, the conventional process of seamless steel pipe is difficult to meet the requirements of users; All 12Cr1MoV alloy pipe manufacturers are carrying out scientific research to improve the corrosion resistance of their pipeline pipes and stabilize their service performance in low-temperature and high-temperature environments.
