Water wall panels are the main heating surface of boilers, composed of numbers of rows of steel tubes, arranged around the boiler corner. Inside is the flowing water or steam, and the outside accepts the heat of the flame in the furnace of the boiler, mainly absorbing the radiation heat of the high temperature combustion products in the furnace. 20g High-Pressure Corrosion Resistance Seamless Boiler Pipe20G High-pressure Boiler Seamless Steel Pipe It is a kind of boiler tube with high strength, high oxidation resistance and good stability. Its main purpose is to manufacture various superheater tubes working in ultra-high temperature and high pressure environment.
GB/ASME Standard 20G Boiler Membrane Wall for Power Plant Boilers Introduction . Water wall panels are used in modern industrial boilers to replace steam generating tubes. They are designed to absorb high temperature radiant heat given off by the flame in the fuel chamber, and reduce heat loss caused by the air tightness. ASTM A192 Boiler Steel Pipe Knowledge - SHINESTAR STEEL According to the use temperature, boiler steel pipe can be divided into general boiler tube and high pressure boiler tube. Manufacturing methods:The operating temperature of general boiler tube is under 450 , the domestic boiler steel pipe mainly uses 10# and 20# carbon steel through hot rolled or cold drawn to manufacture. The high pressure boiler tubes are usually in high temperature and high ASTM A210 ASME SA210 Grade C Seamless Tubes-Boiler Tubes ASTM A210 Grade C Seamless Medium-Carbon Steel Boiler and Superheater Tubes Standard:ASTM A210/A210M ASTM A210 Grade C Seamless Boiler and Superheater Tubes sizes and thicknesses usually furnished to this specification are 1/2 in. to 5 in.
