What is the role of the oil pipeline

　The oil pipelinw is widely used in the manufacture of structural parts and mechanical parts, such as oil drilling rod, automobile drive shaft, bicycle frame, and steel scaffolding used in the construction and construction of mobile pictures. The use of oil pipe to make ring parts can improve material utilization, simplify the manufacturing process, save materials and work hours, such as rolling bearing rings, Jack sleeves, etc., which have been widely used in the manufacture of 6" Sch160 API 5L Psl1 Petroleum Oil Pipeline. Petroleum pipes are also indispensable materials for various conventional weapons. Barrels, barrels and so on are made of petroleum oil pipeline.

　　According to the shape of cross section area, the oil pipeline can be divided into circular pipes and special-shaped pipes. Due to the equal circumference, the largest area of the oil pipeline is the use of a circular tube to transport more fluid. Seamless steel pipe (GB9948-88) for petroleum cracking is a seamless steel pipe for furnace pipe, heat exchangers and pipes for petroleum refineries. The oil drilling pipe (YB528-65) is a seamless steel pipe used for thickening or thickening of oil drilling ends. There are two kinds of steel pipe split and no wire. The connection between the wire and the pipe is connected with the tool joint.
