Silicon carbide ceramic sealing ring

Silicon carbide ceramic sealing ring is a kind of high performance sealing material.

Main features:
High hardness: The hardness of silicon carbide ceramics is close to that of diamond, with a Mohs hardness of 9.5, which makes it have excellent wear resistance.
High corrosion resistance: Silicon carbide has good corrosion resistance to most acids, alkalis, and solvents, and can be used for a long time in harsh chemical environments.
High temperature resistance: Silicon carbide ceramics can withstand temperatures up to 2700 degrees Celsius, making them suitable for extreme high temperature environments such as high temperature furnaces and high temperature reactors.
High strength: It has excellent strength characteristics and can withstand high mechanical stresses and loads, ensuring stability in high temperature and high pressure environments.
Low coefficient of friction: Silicon carbide ceramics have a lower coefficient of friction, especially when combined with graphite materials. The coefficient of friction is lower than that of alumina ceramics and cemented carbide, reducing energy loss and wear rate.
Thermal shock resistance: Silicon carbide exhibits excellent thermal shock resistance, capable of withstanding the impact of rapid temperature changes and thermal stress, maintaining structural integrity.
High thermal conductivity: Silicon carbide has good thermal conductivity and can effectively conduct heat, making it suitable for applications that require high thermal conductivity.

Main purpose:
Chemical industry: used for wear-resistant and corrosion-resistant seals, suitable for high-speed rotating equipment such as pumps and mixers.
Petrochemical: In high-temperature, high-pressure pumps and valves, improve the reliability and safety of equipment operation.
Aerospace: Sealing systems for liquid-fueled rocket engines to ensure seal reliability under extreme conditions.
Automotive industry: used for engine sealing components to reduce energy consumption and improve engine efficiency.
Metallurgical industry: suitable for sealing requirements under high temperature conditions, such as the roof of high temperature furnaces, grinding media, etc.
Mechanical engineering: used for various mechanical seals, such as static rings, rings, flat rings, etc., to ensure the normal operation of equipment.

Due to its excellent physical and chemical properties, silicon carbide ceramic sealing rings are widely used in many fields, especially in high temperature, high pressure and corrosive environments.
