Boiler&heat-Exchanger Tube

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
