what is pipeline

Followed the pipeline steel plate skill development and the progress of the welded pipe forming, welding skills, pipeline with the use of the welded pipe is gradually expanding, especially in the advantage of large diameter welded pipe class scope increasingly wet, with capital, the elements of welded pipe has been dominant in line pipe category, the constraint of stainless steel seamless line pipe.In 2004, the output value of seamless pipeline is about 400,000 t, steel grade includes x42-70, varieties of onshore pipeline and submarine pipeline.

The production of high steel grade pipe is now the choice of micro-alloying heating process, stainless steel seamless pipe production cost is significantly higher than welded pipe, and with the progress of steel grade, such as X80 above steel grade pipe to carbon equivalent constraints, seamless steel pipe practice process is difficult to meet user requirements;Now each 12Cr1moV alloy pipe production factory is carrying out scientific research work in order to improve the anti-corrosion function of its pipe and the stable use function in the low-temperature and high-temperature environment.In this regard, pansteel group chengdu iron and steel co., ltd. has begun process transformation.

The API pipeline is a pipeline attributed to the U.S. petroleum code. The pipeline is a pipeline that transports oil, gas, and water pumped out of the ground to the oil and gas industry.The pipe pipe consists of seamless pipe and welded steel pipe with flat end, threaded end and socket end;The connection method is end welding, coupling connection, socket connection and so on.
