Introduction of cemented carbide seals

Dec 24, 2018

An alloy material produced by a powder metallurgy process from a hard compound of a refractory metal and a binder metal. Cemented carbide has a series of excellent properties such as high hardness, wear resistance, strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which remains basically unchanged even at a temperature of 500 ° C. It still has a high hardness at 1000 °C.

In the manufacturing process of the valve, when the bad working condition is selected, our butterfly valve, hard sealing butterfly valve, gate valve, globe valve, and the hard alloy on the sealing ring of the butterfly plate wear wear-resistant effect, the valve is in The use of the medium ensures the effect of the sealing surface.
