1, the structure of seamless pipe (GB/T8162-2008) is used for general structure and mechanical structure of seamless steel pipe.
2, the transmission fluid with seamless steel pipe (GB/T8163-2008) general seamless steel pipe for conveying water, oil, gas and other fluids.
3, low and medium pressure boiler seamless steel pipe (GB3087-2008) is used in the manufacture of a variety of structures is low and medium pressure boiler superheated steam pipes, high-quality carbon structural steel hot boiling water pipe and locomotive boilers, superheated steam pipe and arch brick works rolled and cold drawn (rolled) seamless steel pipe.
4, the high-pressure boiler seamless pipe (GB5310-2008) is used in the manufacture of high pressure and over pressure water tube boiler heating surface with high-quality carbon steel, alloy steel and heat-resistant stainless steel seamless.
5, fertilizers, equipment with high pressure seamless steel pipe (GB6479-2000) is applicable to the working temperature of -40 ~ 400 ℃, working pressure of 10 ~ 30Ma chemical equipment and pipeline quality carbon structural steel and alloy steel seamless steel pipe.
6, petroleum cracking seamless steel pipe (GB9948-2006) is applicable to petroleum refinery furnace tubes, heat exchangers and pipe seamless steel pipe.
7, geological drilling pipe (YB235-70) for the geological department core drilling, use of steel pipes, can be divided by end-use drill pipe, drill collars, the core pipe, casing and precipitation tubes.
8, diamond core drilling with seamless steel pipe (GB3423-82) is used for diamond core drilling, drill pipe, seamless steel tubes of the core rod, casing.
9, oil drilling pipe (YB528-65) is a seamless steel pipe used for oil drilling at both ends of thickening or external upset. Steel tube sub-threading and threading two Threading Pipe Fittings links, non-threading works butt links with the tool joints.
10, the ship carbon steel seamless steel pipe (GB5213-85) is to create a ship of Class I pressure piping, grade II pressure piping, boilers, and overheating of the uses of carbon steel seamless steel pipe. Carbon steel seamless pipe wall temperature does not exceed 450 ° C, alloy steel seamless pipe wall temperatures in excess of 450 ° C.
11, automobile axle casing seamless steel pipe (GB3088-82) manufacturing automobile axle casing and the drive axle shell axis effective quality carbon structural steel and alloy structural steel hot-rolled seamless steel pipe.
12, the diesel engine manufacture diesel injection system, high pressure pipes cold-drawn seamless steel pipe with high-pressure tubing (GB3093-2002).
13, hydraulic and pneumatic cylinder with precision internal diameter seamless steel pipe (GB8713-88) is used in the manufacture of hydraulic and pneumatic cylinder with precision inner diameter cold drawn or cold rolled precision seamless steel tubes.
14, cold drawn or cold rolled precision seamless steel pipe (GB3639-2000) is used for mechanical structure, hydraulic equipment, high dimensional accuracy and good surface finish of cold drawn or cold rolled precision seamless steel tubes. Use precision seamless steel tube manufacturing mechanical structure or hydraulic equipment, etc., can greatly reduce the mechanical processing time, improve material utilization, and help to improve the product quality.
15, the structure with stainless steel seamless pipe (GB/T14975-2002) is widely used in chemical, petroleum, textile, medical, food, machinery and other industrial corrosion of piping and structural parts and components made of stainless steel hot-rolled (extrusion, expansion) and cold drawn (rolled) seamless steel tubes.
16, fluid transportation using stainless steel seamless pipe (GB/T14976-2002) is made of stainless steel, hot rolled (extrusion, expansion) and cold drawn (rolled) seamless steel pipe for conveying fluids.
17, shaped seamless steel pipe is the general term in addition to the seamless steel tubes of the tube other than the cross section shape. Shaped seamless steel pipe wall thickness according to different shapes and sizes of steel pipe cross-section can be divided into (code D), ranging from wall thickness Shaped seamless steel pipe (codenamed BD) variable diameter Shaped seamless steel pipe (code for the BJ). Shaped seamless steel tubes are widely used in various structural parts, tools and mechanical parts. And tube, Special Pipes generally have a greater moment of inertia and cross-section modulus, flexural and torsional capacity, can greatly reduce the structural weight saving steel.
18 low-temperature pipe seamless steel pipe (GB/T18984-2003) applies to -45 ° C ~ -195 ° C cryogenic pressure vessel piping and low temperature heat exchanger tubes.
