- Scope
- This standard specifies the representation method, type and main dimensions, technical requirements, test methods and inspection rules of reaction sintered silicon nitride sealing rings for mechanical seals. This standard is applicable to water, oil, solvents and other fluid media except strong alkali, hydrofluoric acid and some organic acids with a seal cavity pressure less than 2MPa and a temperature of -30°C to 200°C; reaction sintered silicon nitride for mechanical seals The inner diameter of the sealing ring is 16mm~120mm.
