The following are some typical applications of Stellite in power plants:
Valves and seats:
Stellite materials are commonly used to manufacture seats, discs and stem sealing surfaces for high-pressure and high-temperature valves. These parts need to be opened and closed frequently during operation and are susceptible to erosion and wear. Stellite's wear-resistant properties can significantly extend the service life of the valve.
Turbine components:
In steam and gas turbines, Stellite is commonly used as an edge coating for turbine blades, nozzles and guide vanes. These components need to operate under high temperature and pressure conditions, and Stellite's high temperature and corrosion resistance can improve their reliability and lifespan.
Boiler parts:
Certain key components in boilers, such as burner nozzles, air caps and wear-resistant plates, are often made of Stellite materials or coatings. These components need to resist wear and corrosion in high temperatures, pressures and corrosive environments.
Pumps and Seals:
Stellite materials are used to manufacture sleeves, collars and sealing rings of high-pressure pumps. These components operate under high pressure conditions and are susceptible to wear and corrosion. Stellite's high hardness and corrosion resistance can ensure long-term stable operation of the pump.
Nuclear power plant components:
In nuclear power plants, Stellite materials are used to make the ends of reactor control rods, supports for fuel assemblies and other critical components. Its radiation resistance and high temperature resistance make it important for use in nuclear power plants.
Welding and Repair:
During the inspection and maintenance of power plant equipment, Stellite electrodes or wires are often used for repair welding to restore the size and performance of worn parts. Welded parts can be put back into use, extending the overall life of the equipment.
