Information

API pipeline pipe belongs to the United States oil standard pipeline pipe, pipeline pipe is extracted from the ground oil, steam, water, through the pipeline pipe to the oil and natural gas industry enterprises. The pipeline pipe comprises a seamless pipe and a welded steel pipe, the pipe end is a flat end, with a threaded end and a socket end; The connection mode is end welding, collar connection, socket connection and so on.

Treatment process:

With the development of the pipeline steel plate technology and the progress of welded pipe forming, welding technology, the application range of the pipe with welded pipe in gradually expanding, especially in the large diameter welded pipe class scope the advantage of more wet, and cost factors, welded pipe has been dominant in the field of line pipe, which limits the development of stainless steel seamless steel line pipe. 2004 seamless pipeline production of about 400000 t, including x42-70 steel grade, varieties of onshore pipelines and submarine pipelines.

The production of high steel grade pipeline pipe is currently using microalloying heating treatment process, the production cost of stainless steel seamless pipe is significantly higher than the welded pipe, and with the improvement of steel grade, such as X80 steel grade pipeline pipe on the limit of carbon equivalent, the conventional process of seamless steel pipe is difficult to meet user requirements; At present, each 12Cr1moV alloy pipe production factory is in order to improve the corrosion resistance of the pipeline pipe, low temperature, high temperature environment in the use of stable performance and scientific research work. In this respect, Chengdu Iron and Steel Co., Ltd. of Panzhihua Steel Group has embarked on the process transformation.
