Silicon Carbide and Silicon Nitride Seal Faces for Nuclear Reactor Coolant Pumps
Seal faces require intricate designs and must be highly machined, ground and lapped in order to conform to very tight tolerances required in nuclear reactor coolant pumps.
Seal faces are available in three materials: sintered alpha silicon carbide, sintered silicon carbide with excess carbon, and hot pressed silicon nitride.
What are the key technical considerations when manufacturing seal faces for nuclear reactor coolant pumps?
Seal faces for nuclear reactor coolant pumps must be highly engineered to meet the specific tolerances of the application. These must be machined according to intricate designs, ground and lapped.
What level of quality assurance is required for nuclear reactor seal faces?
Saint-Gobain Performance Ceramics & Refractories is ISO 9001 and ISO 14001 certified. In addition to conforming to end-use specifications, nuclear reactor customers typically require a comprehensive audit of key suppliers involved in the supply chain.
What materials are typically used to make seal faces for nuclear reactor coolant pumps?
Seal faces for nuclear reactor coolant pumps can be manufactured with pressure-less sintered alpha silicon carbide, sintered alpha silicon carbide with excess carbon and hot pressed silicon nitride.
