A brief introduction of seamless pipe’s use
Seamless Steel Tube is divided into hot-rolled (extruded) seamless steel tube and cold-draw
n (rolled) seamless steel tube. Cold-drawn (rolled) tube is divided into round tube and special-shaped tube two kinds. Seamless steel pipe and because of its different uses are divided into the following several varieties: 1. Seamless steel tubes for structural use (GBT8162-2008). Mainly used for general structure and mechanical structure. Its representative material (brand) : Carbon Steel, 20,45 steel; Alloy Steel Q345,20CR, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, etc. . 2. Seamless steel tubes for fluid transmission (GBT8163-2008). The utility model is mainly used for conveying fluid pipeline on engineering and large equipment. Represents Material (brand) for 20, Q345, etc. . 3. SEAMLESS STEEL TUBES FOR LOW and medium pressure boilers (GB3087-2008) are hot-rolled and cold-drawn seamless steel tubes made of high quality carbon structural steel for various structures of low and medium pressure boiler superheated steam tubes, boiling water tubes and locomotive boiler superheated steam tubes, big smoke tubes, small smoke tubes and arch brick tubes. Representative material for 10,20 steel.
Seamless steel tubes (GB6479-2000) for high pressure chemical fertilizer equipment are high quality carbon structural steel and alloy steel seamless steel tubes suitable for chemical equipment and pipelines with working temperature of-40 ~ 400 °C and working pressure of 10 ~ 30 ma. Representative material for 20,16MN, 12CrMo, 12Cr2Mo and so on. 6. SEAMLESS STEEL TUBES FOR PETROLEUM CRACKING (GB9948-2006). The utility model is mainly used for boilers, heat exchangers and pipelines conveying fluid in petroleum smelters. Its representative material is 20,12CRMO, 1Cr5Mo, 1Cr19Ni11Nb and so on. Kill. The steel pipe for geological drilling (YB235-70) is a kind of steel pipe for core drilling, which can be divided into drill pipe, drill collar, core pipe, casing and settling pipe. 8. The seamless steel pipe (GB3423-82) for diamond core drilling is a seamless steel pipe for drill pipe, core rod and casing. 9. The oil drilling pipe (YB528-65) is a seamless steel pipe which is used to thicken inside or outside the two ends of oil drilling pipe. The steel pipe is divided into two kinds: turning wire and non-turning wire. The turning wire pipe is connected with a joint, and the non-turning wire pipe is connected with a tool joint by butt welding. 10. Carbon and carbon manganese steel seamless steel tubes for ships (GB/t 5312-2009) are suitable for the manufacture of marine grade I, II, boiler and superheater carbon and carbon manganese steel seamless steel tubes. Seamless steel tubes for pressure piping system are divided into 3 grades according to design pressure and design temperature. The working temperature of seamless steel tube wall for boiler and superheater shall not exceed 450 °C.526/2000
Kill. Seamless Steel Tube (GB3088-82) for automobile axle shaft sleeve is a kind of high quality carbon structural steel and alloy structural steel hot-rolled seamless steel tube for automobile axle shaft sleeve and drive axle housing axle shaft tube. 12. The high-pressure oil pipe for diesel engine (GB3093-86) is a cold-drawn seamless steel pipe for manufacturing high-pressure pipe of diesel engine injection system. 13. Precise inner diameter seamless steel tubes (GB8713-88) for hydraulic and pneumatic cylinders are cold-drawn or cold-rolled precision seamless steel tubes with precise inner diameter dimensions for the manufacture of hydraulic and pneumatic cylinders. 14. Cold-drawn or cold-rolled precision seamless steel tubes (GB3639-83) are cold-drawn or cold-rolled precision seamless steel tubes with high dimensional accuracy and good Surface finish for mechanical structures, hydraulic equipment. The choice of precision seamless steel pipe manufacturing mechanical structure or hydraulic equipment, can greatly save machining time, improve material utilization, and help to improve product quality.
