ISO / ASME Standard Spare Part Double H Type Boiler Fin Tube Heat Exchange


Product Description


The finned tube is a heat exchanger.Is to improve the heat exchange efficiency, usually in the heat exchange pipe surface by adding fins, increase the heat exchange pipe surface area (or internal surface area), so as to improve the heat exchange efficiency, such a heat exchange pipe.

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.


Manufacture


High frequency and high frequency welding spiral finned pipe is one of the most widely used spiral finned pipe at HDB.It is widely used in power, metallurgy, cement industry waste heat recovery and petrochemical industry.High frequency welding spiral finned pipe is in the steel belt winding steel pipe at the same time

, using the skin effect and proximity effect of high frequency current, the steel belt and the outer surface of the steel pipe are heated until the plastic state or melting, and the welding is completed under certain pressure of the wound steel belt.This high frequency welding is actually a solid phase welding.Compared with Mosaic, brazing (or overall hot dip galvanizing) and other methods, it is more advanced in product quality (fin bonding rate is high, up to 95%), productivity and automation.
