The oil pipe is a seamless tube for furnace tubes

　　The steel pipe for geological drilling is a kind of steel pipe used by geological departments for core drilling. It can be divided into drill pipe, drill collar, core pipe, oil pipe and sedimentation pipe.

　　Oil pipe is a kind of long steel with hollow section and no seam around it. Oil pipe is an economic section steel.

　　It is widely used in the manufacture of structural and mechanical parts, such as API 5CT OCTG Seamless Steel Oil Pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction movement. The use of oil cracking tube to make ring parts can improve material utilization and simplify.

　　Manufacturing process, saving material and processing time, such as rolling bearing ring, Jack sleeve, etc., has been widely used to manufacture steel pipes. Petroleum cracking pipe is also an indispensable material for all kinds of conventional weapons. The barrel and barrel of gun should be made of oil pipe. According to the shape of cross section area, the oil pipe can be divided into circular pipes and special-shaped pipes. Because the area of oil pipe is the largest under the condition of equal circumference, more fluid can be transported by circular pipe.
