Teflon tube heat exchangers are made of PFA, PTFE, and FEP capillary tubes. The standard tube diameters are 4.5MM, 6MM, and 12MM, and the wall thicknesses are 0.7mm, 0.8mm, and 1mm. The main result forms are shell and tube and immersive. It has unparalleled chemical and thermal stability (-250 ～ 260 ℃).
F4 heat exchanger tube sheet and tube bundle (φ3 ～ 10mm capillary) are sintered by advanced powder metallurgy process, with excellent performance. Through a unique and advanced welding method, the connection strength between the tube bundle and the tube sheet of the Teflon heat exchanger reaches 1.5 Mpa. It is widely used in heat exchange equipment and is an ideal material for tube heat exchangers, coil heat exchangers and condensers.
Shenglong Teflon heat exchanger performance:
Teflon heat exchanger has super strong corrosion resistance and aging resistance. Because of its excellent temperature resistance, it is suitable for both steam heating and hot water heating;
The Teflon heat exchanger mainly has excellent corrosion resistance. Because Teflon is a chemically inert material, it can work in almost all media except elemental fluorine at high temperatures, molten alkali metals, chlorine trifluoride, uranium hexafluoride, and perfluorokerosene.
Teflon material is non-sticky and therefore has good anti-scaling properties. Due to the chemical inertness, surface smoothness, flexibility, and high coefficient of expansion of the polytetrafluoroethylene tube, it is difficult for the heat transfer surface to scale, which greatly reduces the number of equipment maintenance and ensures a relatively stable heat transfer coefficient and production performance. Long running.
Teflon heat exchanger has good anti-aging performance. Because Teflon does not contain photosensitive genes, it has excellent resistance to atmospheric aging. Its service life is 20 to 30 times that of stainless steel in strong corrosive media;
Teflon heat exchanger has good heat transfer performance. Because the heat exchanger uses thin-walled tubes and the wall thickness is only 0.7mm, 0.8mm, 1mm, it overcomes the disadvantage of low thermal conductivity of Teflon material;
Teflon heat exchanger has low resistance. Because of the small coefficient of friction, low roughness, and particularly good lubricating properties of Teflon, the resistance of the fluid in the tube bundle is smaller than that of the metal tube.
