 Oil pipe (GB9948-88) is applied to the oil refinery furnace tubes, heat exchangers and pipe seamless steel pipe. Oil pipe oil casing oil pipeline 
 OCTG mainly used for oil and gas well drilling and oil and gas transportation, which includes the oil drill pipe, casing, tubing pumping Oil is mainly used to connect drill pipe drill collar and drill bit and pass drilling power. OCTG-weld heat treatment should be given priority before welding and then the furnace heating method, in accordance with certain procedures 
 Geological drilling steel (YB235-70) is a geological department for the use of steel core drilling, use can be divided into the drill pipe, drill collar, core pipe, casing and precipitation tubes. 
 Oil pipe (GB9948-88) is applied to the oil refinery furnace tubes, heat exchangers and pipe seamless steel pipe. 
 Casing is mainly used for drilling and completion of the wall after the support to ensure the drilling and completion process for the normal operation after the oil wells. 
 Oil pipe is a hollow cross-section, no seams around the long bar of steel, oil cracking pipe is an economic cross-section steel. Widely used in the manufacture structural parts and mechanical parts, such as drill pipe, automotive drive shafts, bicycle frames and construction using steel scaffolding. Ring with petroleum cracking pipe manufacturing parts, can improve material utilization, simplify the manufacturing process, saving materials and processing man-hours, such as bearing rings, jack sets, etc., has been widely used to make steel.
