FEP anticorrosive heat exchanging tube and exchanger
FEP has comprehensive advantages that other materials can not compete with, especially its temperature characteristics and corrosion resistance in heat exchangers, which makes FEP heat exchangers widely used in corrosion-resistant industries, such as chemical industry, pickling, electroplating, medicine, anodic oxidation and so on.
FEP heat exchanger has excellent corrosion resistance and aging resistance. Because of its excellent temperature resistance, it is suitable for both steam heating and hot water heating.
FEP heat exchanger is a new type of corrosion-resistant heat exchanger developed in recent ten years. The main results are shell and tube type and immersion type. It has unparalleled chemical and thermal stability (- 200 - 200 C). The tubesheet and bundle of F46 heat exchanger (3-10mm capillary) are sintered by advanced powder metallurgy process, with excellent performances. Through unique and advanced welding method, the connection strength between tube bundle and tube sheet of fep heat exchanger reaches 1.5 Mpa.
Fep heat exchanger has excellent corrosion resistance. Because fep is an inert chemical material, it can work in almost all media except elemental fluorine at high temperature, molten alkali metal, chlorine trifluoride, uranium hexafluoride and perfluorinated kerosene. For example: concentrated hydrochloric acid, hydrofluoric acid, sulfuric acid, nitric acid, phosphoric acid, acetic acid, oxalic acid, caustic sodium, sodium hypochlorite, naphthalene, benzene, xylene, acetone, Aqua regia, chlorine, toluene, various organic solvents, etc.
FEP heat exchanger has good scale resistance. Due to the chemical inertia, smooth surface, winding and high expansion coefficient of fep tubes, it is difficult to scale the heat transfer surface, which greatly reduces the number of equipment maintenance and ensures relatively stable heat transfer coefficient and long-term operation of production.
FEP heat exchanger has good heat transfer performance. Because the heat exchanger is a thin-walled tube with a wall thickness of only 0.5 mm, 0.75 mm and 1 mm, the shortcoming of low thermal conductivity of FEP material is overcome, and its total heat transfer coefficient can reach 150-300 (W/m2.K).
The resistance of fep heat exchanger is small. Because of its small friction coefficient, low roughness and excellent lubrication performance, the resistance of the fluid in the tube bundle is smaller than that in the metal tube bundle; the fep heat exchanger is small in volume, light in weight and compact in structure.
