High Frequency Welding Spiral Type Boiler Fin Tube For Heat Exchanger


Spiral finned tube has been widely used in the heat recovery of coal economizer, air preheater and waste heat boiler, as well as heat exchange equipment in chemical industry and pressure vessel. Our products can be modified according to our customers' needs and the situation.we design and manufacture safe,reliable and efficient spiral fin tubes.it has also completed stand-alone product quality assurance systems.Production of spiral fin tubes are with high heat transfer efficiency, they have flue gas resistance and are designed for a small space.


Product Description

1.Finned Tube Heat Exchangers consist of a shell and finned tubes assembly.

2.Fins are used to increase the effective surface area of heat exchanger tubing.

3.Finned tubes are used when the heat transfer coefficient on the outside of the tubes is appreciably lower than that on the inside;as in heat transfer from a liquid to a gas,vapor to a gas ,such as steam to air heat exchanger, thermic fluid to air heat exchanger, when an extended surface is needed on only one fluid side or when the operating pressure needs to be contained on one fluid side.


Fin tube heat transfer area is 8 times than the light tube, high efficiency heat exchange, more advanced than the other heat exchange products.

Application: Boiler Economizer, Heat Exchange, Power Plant Waste Heat Boiler,Petrochemical Engineering.
