Low temperature steel pipe refers to the steel pipe used in low temperature environment below -10. The steel usually used at low temperature of -10~-196 is called low temperature steel, and the steel used at low temperature below -196 is called ultra-low temperature steel, which has enough notch toughness. Low temperature steel pipe is mainly used in the production of ethylene, propylene, urea, synthetic ammonia, compound chemical fertilizer and washing, purification, desulphurization and degreasing in pharmaceutical industry with petroleum, chemical, natural gas and coal as raw materials, as well as cryogenic equipment manufacturing, ultra-low temperature cold storage, transportation of ultra-low temperature liquefied gas pipeline and its pipe components. High temperature steel pipe is the steel pipe used in high temperature environment. This kind of steel pipe needs to have certain high temperature resistance, will not decline in high temperature environment, but also has certain corrosion resistance.High temperature steel pipe is often used in exhaust pipe, heat treatment furnace, heat switch, incinerator and other pipeline projects that require heat resistance, because the medium in chemical pipeline, power plant boiler pipeline is mostly some high temperature gas, liquid, some also have certain corrosion. 1 ASTM A106 Seamless Carbon Steel Pipe for High Temperature Service 2 ASTM A268 Seamless and Welded Ferritic and Martensitic Stainless Steel Tubing for General Service 3 ASTM A269 Seamless and Welded Austenitic Stainless Steel Tubing for General Service 4 ASTM A312 Seamless, Welded, and Heavily Cold Worked Austenitic Stainless Steel Pipes 5 ASTM A333 Seamless and Welded Steel Pipe for Low Temperature Service 6 ASTM A334 Seamless and Welded Carbon and Alloy Steel Tubes for Low Temperature Service 7 ASTM A335 Seamless Ferritic Alloy-Steel Pipe for High Temperature Service 8 ASTM A358 Electric-Fusion-Welded Austenitic Chromium-Nickel Stainless Steel Pipe 9 ASTM A376 Seamless Austenitic Steel Pipe for High Temperature Service 10 ASTM A409 Welded Large Diameter Austenitic Steel Pipe for Corrosive or High Temperature Service 11 EN 10216-2&4 Seamless Steel Tubes for Pressure Purposes with Specified Elevated and Low Temperature Properties 12 EN 10217-2&4&5&6 Welded Steel Tubes for Pressure Purposes with Specificated Elevated and Low Temperature Properties 13 JIS G3456 Carbon and Alloy Steel Pipes for High Temperature Service 14 JIS G3458 Alloy Steel Pipes for High Temperature Sevice 15 JIS G3459 Stainless Steel Pipes for Corrosion Resistance and Low&High Temperature Service 16 JIS G3460 Carbon and Alloy Steel Pipes for Low Temperature Service 17 JIS G3464 Steel Heat Exchanger Tubes for Low Temperature Service 18 GB/T 18984 Seamless Steel Pipes for Low Temperature Service Piping 19 GB/T 32970 Longitudinal Submerged-Arc Welded Steel Pipe for High Pressure Service at High Temperatures
