    FIELDS OF APPLICATION
    . the petroleum, chemical and petrochemical process 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.

    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 lends 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 noble 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. L1 max. = 12 000 mm Fin Thickness = 0,3 - 0,4 mm Fa = Outer Tube Surface Area incl. Surface Area of Fins L2 max. = L1 -2t x = acc. to clients specification Fi = Interior Tube Surface Area per Meter (m2/m) FZR = Uncovered Tube Area between the fins
