Carbide sealing rings are made from tungsten carbide powder as raw material, with an appropriate amount of cobalt powder or nickel powder added as binder. They are pressed into a ring shape through certain molds and sintered in a vacuum furnace or hydrogen reduction furnace. It is a relatively common production and processing product among carbide manufacturers. Because it has high hardness, good anti-corrosion performance and strong sealing property, it is widely used in petrochemical and many other sealing industries.
carbide sealing rings are composed of hard metals. They are stronger than titanium rings and more durable than gold rings. It is also very hard, but it is not scratch-resistant. carbide sealing rings can only be scratched by diamonds or corundum products containing minerals.
carbide sealing rings possess characteristics such as wear resistance and corrosion resistance, and are widely used in mechanical seals in fields like petroleum and chemical engineering. Their product types include flat rings, table rings, and other special-shaped rings. Let's take a look at what features it has:
After fine grinding, the appearance meets the precision requirements, with extremely small dimensions and tolerances, and extremely superior sealing performance.
2. Corrosion-resistant rare elements are added to the process formula, making the sealing performance more durable.
3. Made of high-strength and high-hardness carbide material, it does not deform and is more resistant to pressure.
The material of the sealing ring must have sufficient strength, hardness, wear resistance, corrosion resistance and impact toughness, etc.
Meanwhile, carbide sealing rings also need to have good processability and reasonable economic efficiency. Among them, wear resistance, corrosion resistance and resistance to thermal cracking are the most important requirements. As we all know, cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance. Especially its high hardness and wear resistance remain basically unchanged even at 500℃, and it still has a very high hardness at 1000℃. Therefore, carbide sealing rings have become the most widely used product among mechanical sealing parts.
As the most widely used mechanical seal product, its demand is constantly increasing along with the development of the economy and the improvement of technology. carbide sealing rings can be classified into various grades based on different binder phases. Based on Xidi's many years of production experience, the carbide sealing ring grades that users use more frequently are 6%Ni and 6%Co carbide materials. The carbide sealing rings of this grade have higher hardness and wear resistance, and also have superior anti-corrosion performance.
