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.
