High Temperature Resistance Silicon Carbide Ceramic Pipe/Refractory Sic Silicon Carbide Tube for Sale

  

 
 The thermal conductivity of SiC is almost equal to that of commonly used graphite tubes, and far better 
than all of other tube materials available. Its thermal conductivity is twice that of tantalum, 5 times that of 
stainless steel, 10 times that of Hastelloy, 15 times that of glass and 50 times that of Teflon. The result is 
higher efficiency while requiring less heat transfer area. 
 Because of its good thermal conductivity and excellent mechanical properties, the pressureless sintered 
sic is the preferred material for heat exchange tube parts. Its relative density reaches 98% or more,and SiC 
is completely impervious without use of any impregnants. It is 50% harder than tungsten carbide. So it 
offers superb wear resistance and total impermeability at extreme temperature and pressure, and allows 
higher velocity and improved heat transfer. It's hardness also means no contamination in high-purity 
applications.

   The pressureless sintered silicon carbide ceramic products produced by our company are made of ultra-fine 
silicon carbide powder sintered at high temperature. The silicon carbide content is above 98%, the product 
density is ≥3.10g/cm³, without free silicon. The performance indexes of the products reach the international 
advanced level (to the technical standards of Morgan in England and Saint-Gobain in France).What's more, the 
products have a great deal of technical advantages, such as high mechanical strength, high hardness, wear 
resistance, high temperature resistance, strong acid and alkali corrosion resistance, oxidation resistance, 
thermal shock resistance, good thermal conductivity, extreme cold and heat resistance and high temperature 
creep resistance. As a result, the products are widely used in many higntch fields, such as military industry, 
aerospace, nuclear power, metal smelting, high-temperature furnace, lithium-ion battery production, powder 
metallurgy, ceramic chemical machinery, ultra-fine grinding, papermaking, medicine and so on.
