Silicon carbide sealing ring
For CORESIC® SP silicon carbide seal ring, small size and large batch seal ring can be formed by efficient dry pressing, large size and small batch seal ring can be formed by isostatic pressing, further grinding, inner and outer circular processing, drilling, grooving and other precision processing can be made according to the design drawings.
Typical application
Engine cooling water pump
Chemical Technology
Petroleum refining
High-speed compressor
Nuclear reaction cooling water pump
General industrial pump
Features and advantages
High hardness, high wear resistance and long life.
Comprehensive corrosion resistance.
High thermal conductivity and low thermal expansion coefficient, with excellent thermal shock resistance.
With high strength and low coefficient of friction, silicon carbide sealing rings can be used in high-speed sealing places.
When used in corrosion resistance, wear resistance, high temperature resistance, thermal shock resistance, high pressure resistance, high speed applications, CoreSiC ® SP SiC sealing surfaces offer better performance than traditional hard surface sealing materials such as alumina, reaction-sintered SiC and Tungsten Carbide.
Specification
CORESIC® SP silicon carbide sealing ring is usually customized according to customer requirements.

CORESIC® SiC is a polycrystalline alpha type silicon carb ide produced by pressureless sintering process of submicron silicon carbide powder in a proper forming process of extrusion, dry pressing or isostatic pressing. The controlled sintering process results in self-bonded fine grain, homogeneous micro-structure sic products which is more than 95% dense, with no traces of free silicon.
• Temperature stability: The mechanical properties such as bending strength, modulus of elasticity, toughness of CORESIC® SiC hardly change with temperature, from close to absolute zero up to 1700°C, that is not suitable for
other materials.
• Extremely universal high corrosion resistance in acidic, alkali, basic media and oxidants -even at high temperatures.
• 100-999mg/cm2yr Notrecommended for service greater than a month
• 50-99mg/cm2yr Not recommended for service greater than one year
• 10-49mg/cm2yr Caution recommended, based on the specific application
• 0.3 to 9.9mg/cm2yr Recommended for long term service
• ‹0.2 mg/cm2yr Recommended for long term service:no corrosion
• CORESIC® SP SiC can be used to produce plates, blocks, headers, tubesheet and other complex shapes by isostatic forming process.
• By using advanced high temperature ceramic welding technology, manufacturing high-value and complex SiC components and modules has been reality.
• Single plate size up to 600*300mm, and the groove width minimum to 0.5mm.
• Single block diameter up to DN500mm.
• Tubesheet size up to diameter 500mm.
CORESICe SE tubes,formed by extrusion process, length can up to 4000mm, used as heat exchanger and microreactor tubes. Upto now, several standard dimensions of tubes have been suppied to markets, more customized dimensions can be also developedaccording to customer requirements.
