Hunan Steel Industrial Zone, No.9 Xiangfu Road, Yuhua District, Changsha, China
The oil pipes are widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, car drive shaft, bicycle frames and moving pictures and it also used in construction steel scaffolding. The oil pipe use of oil cracking tube manufacturing ring parts, it can improve material utilization, simplify.
The manufacturing processes is saving materials and processing hours, such as rolling bearing rings, Jack sets etc. it has been widely used to manufacture steel pipe. Oil cracking tube is the different cross-sectional shape can be divided into round tube and shaped tube. Since the area of the oil cracking tube is the largest under circum- stances of equal length, more fluid can be delivered with a round tube.
Seamless steel pipe of oil cracking (GB9948-88) is suitable for oil refinery furnace tubes, heat exchangers tube and seamless steel pipe.
Oil drilling pipe (YB528-65) is used for oil drilling both ends of the thickening or thickening of the seamless steel pipe. Pipe sub-car wire and not car wire two, car thread tube connection with the joint, not the wire with the butt welding method and tool joints.
