Technical Specification:
The serial integral helical fins on the outside of the tube don’t contact thermal resistance. The fin height is more than 5mm. The outside heat transfer surface area is over 7 times higher than that of plain tube with the sane sizes. We can manufacture the tube with 5FPI, 7FPI, 8FPI, 9FPI, O.D. Φ30-60mm, fin height 5-15mm, maximum straight length 7m.
Application:
The tube especially suitable for gas-gas, gas-water, water-oil heat exchanger, air cooler and heater in power plant, cooler in utin and gas dryer.
