Boiler Spare Parts Fin Tube For Economizer Spiral Fin Tube heat transfer efficiency
About Spare Parts Economizer Spiral Finned Tubes
1. With an aim to increase the heat exchanging efficiency, It's usually to extend the surface area (or internal surface area) by adding fins onto a tube, which, through this manufacturing process, would greatly improve and upgrade the heat transferring efficiency of heating tube, it's called Finned Tube or Fin Tubes.
2. Our products can be modified according to our customers' needs and the situation.we design and manufacture safe,reliable and efficient H-fin tubes.
3. DEHAI BOILER 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.
