Product Description

Solid Plain CuNi Type OD 16mm Refrigeration Copper Tube


CuNi 90 /10 Cooper Tube , OD25.4X1.5WT L Shape Type Cooper Fin Tube


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


Manufacturing process:

The fin strip (normally aluminum and copper) is folded into an L SHAPE and wound onto the base tube surface under tension. The feet of the fins are joined together and cover the finned surface. All the goods shall be Zinc or Aluminum metalized applied by an electro spray arc system coating. The desiccants are put into each package for continental transportation as well. We provide Tube Support Box, Clamp or Spacer Box (Material: Aluminum, Zinc and Stainless Steel).  The goods will be delivered when tube ends are square cut, free burrs, internally dried and air blown clean, externally coated with varnish at both ends of L Type Tension Wound Finned Tube.

It suits to various areas such as Heat exchangers units for power plant(electric, nuclear, thermal and geothermal power plants); High corrosive systems (condensers, evaporators, sea water desalinations, fertilizing, urea systems, ammonia, gas, corrosive acids); The petroleum, chemical and petrochemical industries; The food processing and refrigeration industries; Natural gas treatment;


Acceptance Criteria

API Standard 661(Air-Cooled Heat Exchangers for General Refinery Service) or the delivery conditions (TDC).

General Materials

Popular ASTM Materials

Core Tube Material

Carbon steel, low-alloy steel, stainless steel, brass, copper, cooper-nickel alloys, aluminum bronze, nickel alloys.

1. Carbon Steel: A179, A192,SA210 Gr A1/C,A106 Gr B

2. Stainless Steel: TP304/304L,TP316/TP316L

3. Copper:UNS12200/UNS14200/UNS70600,

CuNi70/30,CuNi 90/10

4. Titanium: B338 Gr 2

Fins Material

Aluminum & Copper.

1. Aluminum(Alu.1100,Alu.1060)

2. Copper.




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 (Reliance) 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.
