ASTM A556/A556M Standard Specification for Seamless Cold-Drawn Carbon Steel Feedwater Heater Tubes 1.  ASTM A556/A556M Scope 1.1 This specification 2 covers minimum-wall-thickness, seamless cold-drawn carbon steel tubes including bending into the form of U-tubes, if specified, for use in tubular feedwater  heaters. 1.2 The tubing sizes covered shall be 5/8 to 1 1/4 -in. [15.9 to 31.8-mm] outside diameter, inclusive, with minimum wall thicknesses equal to or greater than 0.045 in. [1.1 mm]. 1.3 Optional supplementary requirements are provided, and when desired, shall be stated in the order. 1.4 The values stated in either inch-pound units or SI units are to be regarded separately as the standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently ofthe other. Combining values from the two systems may result in nonconformance with the specification. The inch-pound units shall a

What is membrane water wall panel? The Membrane water wall pane l is the main heating part of the boiler, which is composed of several rows of steel tubes, distributed around the boiler furnace. Its interior is flowing water or steam, and the outside receives the heat from the flame in the boiler furnace. It mainly absorbs the radiant heat of high-temperature combustion products in the furnace, in which the working medium rises and evaporates. Membrane water wall panel refers to the water wall composed of a gas tight pipe panel welded by flat steel and tubes. The membrane water wall can ensure the furnace has good tightness and can significantly reduce the air leakage coefficient of the furnace and improve the combustion conditions in the furnace for negative pressure boilers. The utility model can increase the effective radiation heating area, thereby saving the steel consumption. Advantages of Membrane water wall panel (1) The membrane water wall has the most complete protective effe

U-shaped Monel 400 Tube|B163 UNS N04400 Tube The structure of monel 400 (UNS N04400, NCu30) alloy is a high-strength single-phase solid solution, which is a nickel based corrosion resistant alloy used in industry very early. Monel 400 (with good comprehensive performance and wide application range, it has become an indispensable alloy due to its good corrosion resistance. Monel 400 is mainly composed of Ni, 30% Cu and a small amount of Fe (1% - 2%). U-shaped Monel 400 tubes are commonly used in various heat exchange equipment, boiler feed water heaters, pipelines, containers, pumps, valves, shafts, etc. in petroleum and chemical processing, seawater desalination equipment, salt production equipment, propeller shafts, Gasoline and water tanks, etc. U-shaped Monel 400 Tube|B163 UNS N04400 Tube Chemical Composition % C Si Mn Ni Cu Fe Min 　 　 　 63 28 　 Max 0.3 0.5 2 　 34 2.5 U-shaped Monel 400 Tube|B163 UNS N04400 Tube corresponding grade Monel400 　 　 　 Ni68Cu28Fe JIS ASTM UNS 、 SAE DIN EN
