Product Name: | Corrosion Resistant Si3N4 Ball Valve For Chemical Pumps |
Silicon nitride ceramic is an excellent high-temperature engineering material. It has the characteristics of wear resistance, corrosion resistance, high temperature resistance, oxidation resistance, thermal shock resistance, good insulation, and high thermal conductivity. As a new material with the best comprehensive performance, silicon nitride ceramic is widely used in coal chemical industry, new energy, non-ferrous metal casting, metal smelting, aerospace and other fields.
Silicon nitride ceramic ball valve
Silicon nitride ball valve can be used for various bearings with extreme performance requirements, as well as valve balls and measuring balls in chemical pumps, high temperature pumps, and metering pumps.
Features:
It is 59% lighter than steel, reducing the centrifugal force of high-speed operation.
The modulus of elasticity is 44% larger than that of steel, and the amount of deformation is small.
The coefficient of thermal expansion is small and can withstand sudden temperature changes.
It is more resistant to chemical corrosion than steel, and there is no adhesive wear.
