Oil Pipe API 5CT divided into K55, N80, L80, P110 and other steel grade. Petroleum Steel Pipe: Tubing J55 (37Mn5) My job Petroleum Steel PipeCasing J55 (37Mn5) Coupling tube J55 (37Mn5) Oil pipe (GB9948-88) is applicable in the oil refinery furnace tubes, heat exchangers and pipe seamless steel pipe. Geological Drilling Pipe (YB235-70) is for the use of the geological department of the steel core drilling, according to use can be divided into the drill pipe, drill collar, core pipe, casing and sedimentation tubes. Petroleum Steel Pipe is a kind of hollow cross-section, strip joints neighboring steel, petroleum cracking pipe is a kind of economic cross-section steel. Function: widely used in manufacture of structural parts and mechanical parts, such as oil drill pipe, automotive drive shafts, bicycle frames, as well as construction using steel scaffolding. Petroleum cracking tube manufacturing circular parts, can improve material utilization, simplify the manufacturing process, saving materials and processing man-hours, such as the rolling bearing rings, jack sets and so on, has been widely used to make steel. Oil cracking pipe, or a variety of non-conventional weapons, the lack of materials, barrel, barrel of oil cracking pipe and so on should be to make. Oil cracking tube by cross-sectional area of different shapes can be divided into pipe and the Rectangular pipe. As the perimeter of equal conditions, the largest area of oil cracking tubes, using a circular tube can be more fluid delivery.
