The fins are rolled out of the wall of the plain tube. Tube and fin are consisting of one piece. Advantages: Excellent heattransfer, good bending properties, wide range of material can be used.

Materials:

Carbon Steel, Low Alloy Steel,Stainless Steel, Nickel, Nickel-Copper, Nickel-Chrom-Iron, Copper Alloy, Aluminium Alloys, Titanium

Fields of application:

Chemical-, Petrochemical- and Petroleum Industries. Used in condensers, oilcoolers, waterheaters, heatexchangers, evaporators and heat-recoverers.

Manufacturing process:

The fins are rolled out of the wall of the plain tube by use of a pass roller. Tube and fin consist of same piece.

Advantages:

Economical solution of heatexchange problems of media with different heat conduction abilities or different current conditions. High chemical-, thermal- and mechanical resistance, suitable for rough working conditions.

Applications: Low-Fin Tubes are used in shell and tube type heat exchangers to improve energy efficiency in refining, petrochemical, LNG, power generation, refrigeration, heating and air conditioning plants world-wide.

Benefits: Increased surface area for heat transfer, smaller heat exchanger, less number of heat exchangers, reduced equipment and installation cost, debottlenecking existing heat exchangers, upgrading to corrosion resistant alloys without sacrificing heat transfer efficiency, and reduced fouling (in some cases).
