PTFE tube shell type lining heat exchanger

Heat exchangers are indispensable equipment for heat exchange and transfer in chemical production processes. In the heat exchange, there are often some corrosive and highly oxidized materials. Therefore, the materials required to manufacture the heat exchanger have strong corrosion resistance. It can be made of non-metallic materials such as graphite, ceramics, glass, and metal materials such as stainless steel, titanium, tantalum, and zirconium. However, the use of graphite, ceramics, glass and other materials made of fragile, bulky, poor thermal conductivity and other shortcomings, the use of rare metals such as titanium, tantalum, zirconium and other heat exchangers are too expensive, stainless steel is difficult to withstand many corrosive media And a medium that produces intergranular corrosion.

Characteristics of PTFE heat exchanger:

Has good corrosion resistance: Due to the chemically inert material of polytetrafluoroethylene, except for elemental fluorine at high temperature, molten alkali metal, chlorine trifluoride, uranium hexafluoride, perfluoro kerosene, almost all Working in the media.

Good anti-pollution property: Due to the inertness, surface smoothness, flexibility and high expansion coefficient of the Teflon tube, it is difficult to scale the heat transfer surface, greatly reducing the number of equipment maintenance and ensuring a relatively stable transmission. Thermal coefficient and long-term operation of production.
