What is line pipe
Line pipes were compiled and released by the American Petroleum Institute, and were transmitted to my country through various channels. Now there are such pipelines all over the world, which can be said to be universal. The main mode of operation of the line pipe is actually to transport the oil, natural gas or water pumped out of the ground to the oil and gas industry enterprises through this line pipe.

The main purpose
People mainly use it for transportation of gas, water and oil in the petroleum and natural gas industry. Because of its excellent bearing capacity and hardness, it can be trusted by people when it is used.

specification
The specification of the line pipe is API SPEC 5L-2011. It is mainly two kinds of seamless and welded pipes. The pipe ends of the line pipe are divided into flat ends, threaded ends and socket ends. There are also many connection methods, namely end Welding, collar connection, socket connection, etc. The main materials for making this kind of line pipe are L245, L360, L418, L480, X65, X70, X80 and other steel grades, and the steel grades of different materials have different functions.

The pipeline steel pipe products of Baotou Steel Pipe Co., Ltd. have supplied batches of steel grades below X65, and the products have been successfully exported to Germany, Canada, Brazil, Singapore, Egypt, South Korea, the United Arab Emirates and other countries; X70 steel grade pipeline steel pipes have been successfully industrialized; X52 steel Grade cryogenic pipeline steel pipe has completed laboratory research work. With the increasing consumption of hydrogen sulfide-resistant pipeline steel pipes, in recent years, Baotou Steel has been devoting itself to the development of hydrogen sulfide-resistant pipeline steel pipes and offshore service pipeline steel pipes, among which L290NS hydrogen sulfide-resistant pipeline steel pipes have passed the performance evaluation test of Xi’an Pipe Materials Research Institute , and batch supply; L360QS has completed laboratory development work. As the 159PQF unit and 460PQF unit have been put into operation, Baotou Steel already has the technological conditions to produce high-grade hydrogen sulfide corrosion-resistant pipeline steel pipes and offshore service pipeline steel pipes.
