ASME SB163 NO4400 G Type Finned Tube For Economizers and Heat exchangers
G-Type Finned Tubes are widely used in industries such as petrochemicals, machinery, metallurgy, rubber, printing and dyeing, pharmaceuticals, food, electricity, automobiles, drying, etc. They are important heat transfer components for decomposition furnaces, converter convection sections, air preheaters, economizers, heat exchangers, crystal devices, radiators, and heat pipe technology. Especially steel radiators, they are widely used in industrial and commercial buildings such as offices, residences, hotels, workshops, greenhouses, etc. They play a crucial role in heating Outstanding role.
UNS N04400 nickel copper chemistry has a high-strength single-phase Solid solution metallurgical structure. Alloy UNS N04400 has higher corrosion resistance than nickel under reduction conditions and is more resistant to corrosion than copper under oxidation conditions. This brand has been widely used in applications that require strong resistance to corrosive environments such as acid, alkali, and high-temperature steam. It is almost unaffected by stress corrosion cracking (SCC) caused by chloride and most freshwater conditions. Alloy UNS N04400 is a very tough material (measured through impact testing) that exhibits excellent mechanical properties under conditions below zero. Even if cooled to the temperature of liquid hydrogen, it will not undergo ductile brittle transition. On the other side of the temperature range, alloy UNS N04400 performs well at temperatures up to 1000 ° F.
