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

The heat exchange area of the finned tube includes the effective surface area of the base tube and the entire outer surface area of the exposed portion of the fins. Calculation method of heat exchange area of finned tubes (taking steel aluminum finned tubes as an example) For example: a finned tube is 1860mm long, and both ends are 30mm empty without fins. The diameter of the finned tube is 25mm, the bottom diameter thickness is 0.5mm, the tube thickness is 2mm, and the fin spacing is 2. 8mm, sheet thickness 0.35mm, fin outer diameter 57, effective sheet height 15.5mm, what is the heat exchange area of a finned tube? Answer: The calculation of the heat exchange area is generally based on the cumulative addition of all the parts exposed to the air, which can be divided into three parts. 1, the surface area of the base pipe part (the thickness of the sheet needs to be deducted) 2, the top of the fin (the surface area after the effective number of fins is accumulated) 3. The surface area
