Heat exchange is the most important process which is used in the engineering. The device by which one may be able to achieve the heat exchange process is known as heat exchanger. With the help of heat exchanger we can transfer the energy in the form of the heat to the flowing fluid. When the fluid is running continuously in the exchanger it not only changes the effectiveness and quality of the tubes from which the working fluid flows but it also change the properties of the fluid like; the changes in its thermal conductivity, mass flow rate, density and viscosity. On the other hand with the continuous flow of the chemicals mixed fluid from the heat exchanger its metallic counterparts get corroded and it changes the thermal, mechanical and chemical properties of the running fluid from it. So for the betterment of the heat exchanger and the tubes placed in it we may replace the inner tube of the heat exchanger which is made up from the metal with the tube which is not only chemical inert but it is also non –corrosive in nature. This tube is made up of the material known as the fluoropolymer. This material is made by the PFA polymers (perfluopolyethers) whose most important property is its overall same construction. With the help of this tube the steel surface may be become hydrophobic. So when the one tube is became chemical inert the rate of the corrosion is decreased and the life and durability of the exchanger is increased.

Keywords: Perfuoropolyethers , Fluoropolymers , Thermal efficiency , Hydrofobic, (HEX ) Heat Exchanger.
