CuNi 90/10 Shape Type Heat Exchanger Fin Tube OD25.4 X 1.5WT Finned Copper Tubing


ASTM B111/ B111M : Standard Specification for Copper and Copper-Alloy Seamless Condenser Tubes and Ferrule Stock


Quick Detail:


General L-type production capacityGeneral specifications of L type fin tubes

Finning Facility: 7 finning machines;

Daily capacity up to 5000 meters;

Fin type: Solid plain

Tube OD: 16mm Min~50.8mm max.

Tube Length: 18,000mm max.

Fin Height: 16.5 mm max.

Competitive Advantage:

  1. We have more than 10,000 square meters workshop, including 7 finning machines, daily production capacity up to 5,000 meters.
  2. The finning machines are designed and assembled by ourselves (YUHONG) and we can offer you finning machines and all accessories etc...
  3. This method of manufacturing L tension type enables us to place the finning on a very thin-walled tube with is particularly desirable when using high value alloys (titanium, stainless, copper, nickel).The tube can withstand a temperature of up to 150°C without the risk of atmospheric corrosion or thermal stress.
  4. L TYPE fin tubes provide contact area between the fin strip and the tubes surface and protect the tube wall from atmosphere corrosion. This L TYPE design is much economical than LL, KL, even G-embedded type.
