Heat Exchanger Tubes

　　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.

　　Silicon carbide is one of the hardest high performance material available for heat exchanger tube.Its density is excess of 98%of the theoretical 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.
