Overview
Finned tube is composited with iron-aluminum or copper-aluminum
tube rolling out the fin, which feathers are tightness, small heat
resistance, good heat transfer performance, high strength, small
flow losses, strong corrosion resistant performance, not easy to
deformation and a long working lifetime in cold and hot
condition,etc.
According to user needs, we can produce all kinds of steel strip
winding finned tube and steel aluminum composite finned tube. As
the heat transfer element finned tube works long-term in high
temperature and flue gas condition, such as finned tube in the
boiler heat exchanger which use conditions are as high temperature
and high pressure and corrosive atmosphere, should have a high
performance metrics and they are as follows:Anti-corrosion
,Anti-wear,lower contact resistance ,Higher Stability,Anti-dust
stratification.
This intergral low finned tubes are widely used as heat transfer tubes because of their large external surface area and high heat transfer performance compared with a plain tube. This enhanced surface fin tubes allow our customers to either reduce the size of the heat exchanger or increase its perfornance. The low finned tubes we manufacture are designed to meet the most efficient and durable thermal performance for the most challenging situations and long lasting service life.
