Structural steel pipe refers to the steel pipe mainly used in general engineering structure and mechanical structure.Carbon structural pipes are mainly used in factories, bridges, ships and other buildings, such steel is generally used directly without heat treatment. Because of its high strength and comprehensive mechanical energy, alloy structural pipes are widely used in bridges, ships, boilers, vehicles and important building structures. Structural stainless-steel seamless steel pipe is widely used in chemical, petroleum, textile, medical, food, machinery and other industries corrosion-resistant pipes and structural parts.According to the manufacturing method can be divided into seamless structure pipe and welded structure pipe. According to the shape can be divided into circular, square, rectangular, oval and other irregular shapes. 1 ASTM A134 Electric-Fusion (Arc)-Welded (Sizes NPS 16 and Over) Steel Pipe 2 ASTM A139 Electric-Fusion (Arc)-Welded Steel Pipe (NPS 4 and Over) 3 ASTM A252 Welded and Seamless Steel Pipe Piles 4 ASTM A500 Cold-Formed Structural Tubing in Rounds and Shapes 5 ASTM A501 Hot-Formed Welded and Seamless Carbon Steel Structural Tubing 6 ASTM A618 Hot-Formed Welded and Seamless Carbon Steel Structural Tubing 7 EN 10210 Hot Finished Structural Hollow Section of Non-alloy and Fine Grain Structural Steel 8 EN 10219 Cold Formed Welded Structural Hollow Sections of Non-alloy and Fine Grain Steel 9 JIS G3444 Carbon Steel Tubes for General Structure Purposes 10 JIS G3445 Carbon Steel Tubes for Machine Structure Purposes 11 JIS G3446 Stainless Steel Pipe for Machine and Structural Purposes 12 JIS G3475 Carbon Steel Tubes for Building Structure 13 GB/T 3094 Cold Drawn Shaped Steel Tubes 14 GB/T 8162 Seamless Steel Tube for Structure Purposes 15 GB/T 14975 Seamless Stainless Steel Tube for Structural 16 GB/T 18705 Welded Stainless Steel Pipes for Decoration 17 GB/T 30063 Longitudinal Submerged Arc Welded Steel Tubes for Structural Purpose 18 GB/T 34201 Seamless Hot-Rolled Square and Rectangular Steel Tubes for Structure

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

Boiler tube is divided into general boiler tube and high-pressure boiler tube according to the use temperature. General boiler pipe temperature below 350â??, mainly used to manufacture water wall tube, boiling water tube, superheated steam tube, locomotive boiler superheated steam tube and so on.The heat exchanger tube is one of the components of the heat exchanger, which is used to exchange heat between two media, and has high thermal conductivity and good isothermal property. It is a device that can quickly transfer heat energy from one point to another and has little heat loss, so it is called a heat transfer superconductor with a thermal conductivity of thousands of times that of copper.The common materials of boiler and heat exchange tube are carbon steel, low alloy steel, stainless steel, copper, copper nickel alloy, aluminum alloy, titanium and so on. According to the production method it can be divided into seamless steel pipe and welded steel pipe. 1 ASTM A178 Electric-Resistance-Welded(ERW) Carbon Steel and Carbon-Manganese Steel Boiler and Superheater Tubes 2 ASTM A179 Seamless Cold-Drawn Low-Carbon Steel Heat-Exchanger and Condenser Tubes 3 ASTM A192 Seamless Carbon Steel Boiler Tubes for High Pressure 4 ASTM A209 Seamless Carbon-Molybdenum Alloy-Steel Boiler and Superheater Tubes 5 ASTM A210 Seamless Steel Boiler and SuperheaterTubes 6 ASTM A213 Seamless Ferritic and Austenitic Alloy-Steel Boiler Superheater and Heat-Exchanger Tubes 7 ASTM A214 Electric-Resistance-Welded(ERW) Carbon Steel Heat-Exchanger and Condenser Tubes 8 ASTM A249 Welded Austenitic Steel Boiler Super-heater Heat-exchanger and Condenser Tubes 9 ASTM A250 Electric-Resistance-Welded(ERW) Ferritic Alloy-Steel Boiler and Superheater Tubes 10 JIS G3461 Carbon Steel Boiler and Heat Exchanger Tubes 11 JIS G3462 Alloy Steel Boiler and Heat Exchanger Tubes 12 JIS G3463 Stainless Steel Boiler and Heat Exchanger Tubes 13 GB 3087 Seamless Steel Tube for Low and Medium Pressure Boiler 14 GB 5310 Seamless Steel Tube and Pipes for High Pressure Boiler 15 GB 13296 Seamless Stainless Steel Tube for Boiler and Heat Exchanger 16 GB/T 24593 Welded Austenitic Stainless Steel Tube for Boiler and Heat Exchanger
