Description

L,LL,KL Type Fin Tube|DL Fin Tube

The fin strip is shaped into a 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.

L Fin Tube Material Combinations

Core Tube: Carbon steels low-alloy steels, stainless steels, brass, copper, copper-nickel alloys, aluminium bronze, nickel-alloys (Alloy 400 ext.), bimetal, titanium and others

L Fin Tube Fins: Aluminium, Copper

DL Fin TubeL Fin Tube Fields of Application:

• the petroleum, chemical and petrochemical industries

• natural gas treatment

• the steel industry: blast furnace and converter systems

• power generation: steam turbine exhaust condensing

- contact condensing with cooling of circulating condensate

- fossil and nuclear power plants

• air conditioning (freon, ammonia, propane)

• incineration of household refuse

• compressor coolers, ect.

L Fin Tube Manufacturing Process

The manufacturing strip is folded to 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.

L Fin Tube 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 atmospheric corrosion or thermal stress.
