PFA anticorrosive high temperature insulation heat exchanger
PFA has comprehensive advantages that other materials can not compete with, especially its temperature characteristics and corrosion resistance in heat exchangers, which makes pfa heat exchangers widely used in corrosion-resistant industries, such as chemical industry, pickling, electroplating, medicine, anodic oxidation and so on.
PFA 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.
PFA 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 - 260 C). The tubesheet and bundle of PFA 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 pfa heat exchanger reaches 1.5 Mpa.
PFA heat exchanger has excellent corrosion resistance. Because pfa 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.
PFA heat exchanger has good scale resistance. Due to the chemical inertia, smooth surface, winding and high expansion coefficient of pfa 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.
PFA 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 PFA material is overcome, and its total heat transfer coefficient can reach 150-300 (W/m2.K).
The resistance of pfa 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 PFA heat exchanger is small in volume, light in weight and compact in structure.
PFA Tube heat exchanger is made from PFA tube It has non-sticking, heat-resistance, aging resistance, corrosive
resistance, non-flammability and good electric property. It can be solid adhesive for PTFE and also a good adhesive
for laminating various materials. Its working temperature is up to 260 and is an ideal material for circuit board and flat cable
