SILICON CARBIDE (SIC) HEAT EXCHANGER
--------------------------------------------------------------------------------------------------------------------------------------------------------------
As new advanced material, silicon carbide has been widely applied in the extreme environment of high temperature, high pressure, strong corrosion and high wear in chemical, pharmaceutical and metallurgical industries.
Single-phase and Pressureless sintered silicon carbide fulfil high purity, fine grain size and extremely low porosity and other excellent characteristics. It can be a perfect solution if other materials reach their limits such as graphite, stainless steel, tantalum, Hastelloy, Fluoropolymer.
High performance silicon carbide heat exchanger has high strength, high temperature resistance, high heat conduction and comprehensive acid and alkali corrosion resistance. It is especially suitable for high temperature, high pressure, strong acid alkali corrosion, high speed air flow scour, particle wear and other harsh conditions. Its excellent heat exchange efficiency can meet the urgent need of energy saving, emission reduction and environmental protection.
>> Distinct advantages
Extreme corrosion and excellent abrasion resistance: Meets extreme demands for corrosion resistance (HF, bromine, high concentration nitric, mixed acids, bases, oxidants and chlorinated organics.)
