PTFE Heat Exchanger Corrosion Resistance Is Particularly Good
Polytetrafluoroethylene heat exchanger referred to as tetrafluoroethane heat exchanger. Is a small diameter PTFE hose as a heat exchanger components of the heat exchanger, also known as flexible tube heat exchanger. Tetrafluoroethane heat exchanger is mainly used for a variety of highly corrosive media heat transfer, such as sulfuric acid, corrosive strong chloride solution, acetic acid and caustic medium cooling or heating.
The structure of the tetrafluoroethane heat exchanger is shell and tube heat exchanger and immersion heat exchanger two types. Their main parts are composed of many small diameter thin-walled Teflon heat transfer hose. Commonly used tube specifications are a variety of diameter × wall thickness were 3 ~ 25mm × 0.3 ~ 0.1mm. The tube bundle contains 60 to 5000 tubes, each with a polytetrafluoroethylene tape. Tube bundle inserted in a ring, welded into a whole honeycomb tube plate. PTFE Tetrafluoroethane Heat Exchanger The other components of the tetrafluoroethane heat exchanger are common with the common shell-and-tube heat exchangers and submerged heat exchangers with metal pipes as heat transfer modules.
Polytetrafluoroethylene chemical stability is very stable, PTFE Tetrafluoroethane Heat Exchanger particularly good corrosion resistance. Teflon wall surface is smooth, and there is a moderate flexibility, the use of micro-vibration, it is not easy to scale. , The unit unit volume of heat transfer area for the metal tube shell and tube heat exchanger more than 4 times. Flexible Teflon tubing can work safely in the impact and vibration of the fluid, and the tube bundle can be made in a variety of special shapes as needed. PTFE Tetrafluoroethane Heat Exchanger Teflon thermal conductivity is low, mechanical properties worse than the metal, not high temperature. The use of small diameter, thin tube wall, although the thermal conductivity and mechanical properties are compensated, but still only for lower pressure and lower temperature occasions.
PTFE heat exchanger is divided into tube-type and shell-and-tube; tube bundle is the heat exchanger is installed directly in the heat exchanger solution to the container, PTFE Tetrafluoroethane Heat Exchanger to achieve the exchange of heat. Tube-shaped heat exchanger installation, easy maintenance, easy to use; tube-type heat exchanger with a plate (placed on the side of the groove) W-shaped, U-shaped, L-shaped (placed at the bottom), in shape or garden, Shaped and other special shape, can also be formed according to the requirements of customers.
The production of tetrafluoroethane heat exchanger has become more and more mature, and widely used in chemical, pharmaceutical, pickling and other corrosive industries.
