Metal sealing ring is a circular sealing component used to seal mechanical equipment, made of metal material. It is usually used in high-pressure, high-temperature, high-speed, highly corrosive or other harsh working environments to ensure the safe operation and long life of mechanical equipment. The advantages of metal sealing rings include: 1. High temperature resistance and corrosion resistance: Metal sealing rings can work in high temperature and corrosive environments, with a longer service life. 2. High pressure sealing: Metal sealing rings can withstand high pressure, ensuring the safety of mechanical equipment. 3. High speed sealing: Metal sealing rings can work in high-speed rotating mechanical equipment to ensure the normal operation of the equipment. 4. Good stability: The material of the metal sealing ring has good stability and will not fail due to environmental changes. 5. Low maintenance cost: The metal sealing ring has a long service life and low maintenance cost. Metal sealing rings are commonly used in mechanical equipment in industries such as automotive, aviation, aerospace, petrochemical, power, metallurgy, chemical, and pharmaceutical.
