Manufacturing Process
The fins of low finned tubes are obtained by roll forming the outer surface of a plain tube. Tube and fin consist of same piece.This process results in an increase in strength of the finned sections, whereas the plain ends and lands remain soft. Soft annealing of the tubes is required if they have to be suitable for bending or coiling
Fields of Application and Advantage
Chemical, Petrochemical and Petroleum Industries.Used in condensers,oil coolers,water heaters,heat exchangers,evaporators and heat-recoverers.Economical solution of heat exchanger problems of media with different heat conduction abilities or different current conditions.High chemical,thermal and mechanical resistance,suitable for rough working conditions
