We have been supplying customers silicon carbide seal rings with good value and excellent quality. Having advanced powder preparation technology with independent intellectual property rights, we manufacture our seal rings by various molding technologies such as dry pressing, isostatic pressing, squeezing and flow casting and by different sintering technologies such as pressureless sintering, hot-pressing, reaction sintering. Our seal rings have the advantages of high hardness, high wear resistance, low friction coefficient, strong oxidation resistance, good thermal stability and low thermal expansion coefficient and have been widely used in machinery, petroleum, chemical industry, water treatment, aviation, aerospace, shipbuilding, metallurgy, nuclear power and other fields.
