I. Brief introduction of PTFE welding technology

PTFE welding technology is a key F4 welding method in the manufacture of tetrafluoro heat exchanger. Polytetrafluoroethylene, also known as Teflon or Teflon, has excellent corrosion resistance and temperature resistance with strong acids, bases and oxidants. PTFE heat exchanger is used for heating, cooling or condensing in various corrosive environments such as iron and steel pickling, chemical industry, boiler flue gas waste heat recovery, electroplating, pharmaceutical, electric power, flue gas desulfurization and whitening, etc. The welding of PTFE tube sheet and tube bundle is the core process in the manufacturing process of PTFE heat exchanger, and the welding process of PTFE determines the quality of heat exchanger.
