● High wear resistance ● High corrosion resistance ● High oxidation resistance ● Strength remains unchanged in high temperature environments ● Thermal shock resistance ● Low density, light weight ● Long service life
Silicon carbide material has excellent corrosion resistance and can be used to transport various corrosive media, including strong oxidizing acids such as 95% concentrated sulfuric acid and nitric acid, as well as strong acids such as hydrofluoric acid and hydrochloric acid, with a wide range of applications. At the same time, due to the excellent heat resistance and impact resistance of silicon carbide material, which does not crack during sudden cooling and heating, it can be applied to harsh working conditions with rapid temperature changes, and has high temperature resistance. The long-term use temperature can reach 200 ℃. It can meet the application requirements of high-temperature corrosive medium circulation for sulfuric acid concentration, phosphoric acid concentration, and other applications.
The use of silicon carbide composite materials and advanced technology and equipment continuously improves the pump casing and impeller repair process, providing a perfect solution for anti-corrosion, wear prevention, and repair treatment of damaged impellers and pump casings. It can extend the service life of the equipment, shorten maintenance cycles, save maintenance and operating costs, and achieve good results in practice.
