We offer an impeccable range of Extruded Finned Tubes made of high quality metal which are widely used in Pharmaceutical, Chemical and Marine industries. Here, a strip of our Extruded finned tube is subjected to controlled and calculated deformation under tension. This optimizes the contact pressure of the bottom of the fins on the base tube and thus optimizes heat transfer. In addition, the fins on the feet significantly enhance the corrosion resistance of the base pipe.
