  Teflon has comprehensive advantages that other materials can not compete with, especially its temperature characteristics and corrosion resistance in heat rs, which makes Teflon heat rs widely used in corrosion-resistant industries, such as chemical industry, pickling, electroplating, medicine, anodic oxidation and so on.

   Teflon heat r has excellent corrosion resistance and aging resistance. Because of its excellent temperature resistance, it is suitable for both steam heating and hot water heating.

   Teflon heat r is a new type of corrosion-resistant heat r developed in recent ten years. The main structure are shell and tube type and immersion type. It has unparalleled chemical and thermal stability (- 250 - 260 C). The tubesheet and bundle of F4 heat r (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 Teflon heat r reaches 1.5 Mpa.

   Teflon heat r has excellent corrosion resistance. Because Teflon 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.

   Teflon heat r has good scale resistance. Due to the chemical inertia, smooth surface, winding and high expansion coefficient of PTFE 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.

   Teflon heat r has good heat transfer performance. Because the heat r 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 Teflon material is overcome, and its total heat transfer coefficient can reach 150-300 (W/m2.K).

   The resistance of Teflon heat r 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 Teflon heat r is small in volume, light in weight and compact in structure.
