ASME SB163 Monel 400, UNS N04400 Nickel Alloy Tube With Embedded G
Type Fin Tube
ASME SB163 UNS N04400 Embedded G Type Fin Tube is known for its
resistant to seawater and steam at high temperatures. In G-type fin tubes, the fins are prepared by embedding the metal
strip into a groove. The latter is formed on a base tube. Placing
the fin on it, back-filling is done – resulting in strong
attachment of the fins to the base tubes. Hence, the name G-Fin
Tubes has come up. The three processes mentioned above are carried
out simultaneously. Maximum heat transfer is expected out of the
g-fin tubes as the fins are strongly attached to the base tube. The embedded G type fin tubes usually work at high temperature
(with around 400 degree Celsius) applications. Made of copper,
carbon, or aluminium, these fins have comparatively less resistance
towards atmospheric corrosion. On the other hand, mechanical
resistance is acceptable. Stainless steel and carbon steel fin
materials are also used, but particular processing and tooling of
the steel fin strips are necessary. Air coolers, radiators, etc use
the g-fin tubes.
