The fin strip is shaped into an L and wound onto the tube surface under tension. Advantages: Core tube extensively protected against corrosion by the fin foot, finning of very thin-walled tubes possible.
Material Combinations:
- Core Tube: Carbon steels low-alloy steels, stainless steels, brass, copper, copper-nickel alloys, aluminum bronze, nickel-alloys (Alloy 400 ext.), bimetal, titanium, and others
- L Fin Tube Fins: Aluminium, Copper
Fields of Application:
- Petroleum, chemical, and petrochemical industries
- Natural gas treatment
- Steel industry: blast furnace and converter systems
- Power generation: steam turbine exhaust condensing (condensing with cooling of circulating condensate)
- Fossil and nuclear power plants
- Air conditioning (freon, ammonia, propane)
- Incineration of household refuse
- Compressor coolers, etc.
Manufacturing Process:
The manufacturing strip is folded from an L shape and then wound around the base tube. The feet of the fins are joined together and cover the whole of the finned surface. Both ends are clamped down to avoid unrolling through damage.
Advantages:
Economic: This method of manufacturing 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 130°C without the risk of atmosric corrosion or thermal stress.
