10 ships with carbon steel seamless pipe (GB5312-85) China Classification Society for Materials and Welding - China Classification Society (CCS) Det Norske Veritas (DNV) specifications - Det Norske Veritas (DNV) Lloyd's Ship Classification Society (LR) specifications - Lloyd's Register (LR) Germanischer Lloyd (GL) specifications - Germanischer Lloyd (GL) American Bureau of Shipping (ABS) specification - American boat class Society (ABS) Bureau Veritas (BV) specifications - Bureau Veritas (BV) Registro Italiano Navale (RINA) specifications - Registro Italiano Navale (RINA) Nippon Kaiji Kyokai (NK) specification - Nippon Kaiji Kyokai ( NK) is to create Class I pressure vessels piping, Ⅱ grade pressure piping, boilers and Superheater carbon steel seamless pipe. Carbon steel seamless pipe wall temperature does not exceed 450 ℃, alloy steel seamless tube wall temperature exceeds 450 ℃. 11. automobile axle casing seamless pipe (GB3088-82) is the manufacture of automobile axle casing and drive shaft tubes Bridge shell quality carbon structural steel and alloy steel hot-rolled seamless pipe 12. A diesel high-pressure tubing (GB3093-86) is the manufacture of high-pressure diesel injection systems of cold drawn seamless tubes. 13. The hydraulic and pneumatic cylinder with precision internal diameter seamless pipe (GB8713-88) is the manufacture of hydraulic and pneumatic cylinder with precision seamless cold drawn or cold rolled with precision diameter size 14. drawn or cold rolled precision seamless tube (GB3639-83) is used for high dimensional accuracy mechanical structure, hydraulic equipment and good surface finish of cold-drawn or cold rolled precision seamless tube. Use a precision seamless tube manufacturing mechanical structure or hydraulic equipment, can greatly reduce machining time, improve material utilization, and help to improve product quality. 15. structures stainless steel seamless pipe (GB / T14975-2002) is widely used in chemical; oil; Textile; medical; food; hot rolling machinery and other industrial corrosion resistant pipes and structural parts and components made of stainless steel (extrusion, expansion) and cold drawn (rolled) seamless pipe 16. Fluid transport stainless steel seamless pipe (GB / T14976-2002) is a hot-rolled stainless steel for conveying fluids (extrusion, expansion) and cold drawn (rolled) No seam tube 17. Shaped seamless pipe is in addition to other general term for seamless cross-sectional shape according to the shape and size of pipe cross-section can be divided into different shaped seamless pipe wall thickness, etc. (code D), not Shaped seamless pipe wall thickness, etc. (codenamed BD), variable diameter seamless shaped (codenamed BJ). Shaped seamless widely used in various structural parts, tools and mechanical parts. and pipe compared Shaped tube generally have a greater moment of inertia and section modulus, greater torsional bending ability, can greatly reduce the structural weight, saving steel. 18. The cryogenic pipe seamless steel pipe (GB / T18984-2003) is used at -45 ℃ ~ -195 ℃ low grade pressure vessel piping and low temperature heat exchanger pipes seamless steel seamless pipe is generally used with 1,020,303,545 other high-quality carbon steel 16Mn, 5MnV low-alloy structural steel or 40Cr, 30CrMnSi, 45Mn240MnB and other structural steel hot-rolled or cold-rolled steel. 1020 low-carbon steel seamless pipe is mainly used for fluid pipes. seamless 4540Cr like carbon steel used to manufacture mechanical parts, such as cars, tractors ... The force is generally seamless pipe parts to ensure the strength and flattening test Hot-rolled steel hot-rolled state or heat treatment delivery; cold to heat treatment delivery to low-pressure boiler seamless pipe: for the manufacture of a variety of low and medium pressure boiler superheated steam pipes, boiling water pipe, water wall tubes and superheated steam locomotive boiler tubes, opium pipe, small pipe and brick arch tubes etc. With high-quality carbon structural steel hot-rolled or Cold-rolled (allocated) seamless. No. 1020 steel is mainly used, in addition to chemical composition and mechanical properties of the outside pressure to do testing, crimping, flaring, flattening and other tests. hot rolled delivery, Cold-rolled (allocated) to heat treatment delivery Jiangyin Lu Bao Pipe Co., Ltd. to provide seamless theoretical weight concept: seamless theoretical formula: (OD - Wall Thickness) * thickness * 0.02466 = Seamless weight per meter kg} {
