Silicon carbide heat exchanger is a new type of heat exchanger using silicon carbide ceramic material as heat transfer medium. High-performance silicon carbide heat exchanger has the characteristics of high strength, high temperature resistance, high thermal conductivity and comprehensive acid and alkali corrosion resistance of silicon carbide ceramics, especially suitable for high temperature, high pressure, strong acid and alkali corrosion, high speed air erosion, particle wear and other harsh working conditions. Its excellent heat exchange efficiency can meet the urgent needs of energy saving, emission reduction and environmental protection.Tube sheet material: steel lined PFA, bidirectional steel 2205, titanium, Ha alloy; Gasket material: perflurane seal ring.
