Finned Tube
To improve the efficiency of heat transfer, usually by adding fins on heat exchange tube to increasing the external surface area (or inner surface area), so to achieve the purpose of improving heat transfer efficiency, this is called the finned tube. Finned tubes are used widely on boiler,evaporater, water pre-heater,super-heater, economizer and air condition.We supply finned tube in U bend, coil and straight length.
We also supply heat pipes and heat exchange equipments of various types and specifications.
The main performance requirements of finned tube:
* anti-corrosion properties
* wear resistance
* low contact resistance
* high stability
* the ability of anti-fouling
