Large Specification Tungsten Carbide Seal Rings For Mining And Oilfield Equipment

At the same time, the carbide sealing ring also needs to have good machining shape and reasonable economy. Among them, wear resistance, corrosion resistance, and thermal cracking resistance are the most important requirements. As we are familiar with, Tungsten carbide have a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance, etc. Especially their high hardness and wear resistance remain basically unchanged even at 500 ℃, and still have high hardness at 1000 ℃. Therefore, cemented carbide sealing rings have become the most widely used product in mechanical seals.

As the most widely used mechanical seal product, its demand is constantly increasing with the development of the economy and the improvement of technology. According to different bonding phases, hard alloy sealing rings can be classified into various grades. Based on Chuangrui Carbide years of production experience, users often use hard alloy sealing ring grades of 6% Ni and 6% Co. Its grade of carbide sealing ring has higher hardness and wear resistance, and its anti-corrosion performance is also superior.
