Tungsten Carbide Sealing Rings

Tungsten carbide sealing rings are also a kind of tungsten carbide product. It is made of 100% purified tungsten carbide powder. To make it stronger, some binders are added, such as cobalt powder and nickel powder. After wet milling and spray drying, the mixture of tungsten carbide powder and cobalt powder will be pressed into a certain shape and size and then sintered in a vacuum furnace or a reduction furnace. Tungsten carbide sealing rings have high hardness, good corrosion resistance, and the ability of sealing, which makes them widely used in the petrochemical industry.

Tungsten carbide sealing rings are made of stiff metal, which is harder than titanium rings. Although tungsten carbide sealing rings are very hard, they can still be worn by diamonds.

Features of tungsten carbide sealing rings

1. After fine grinding, tungsten carbide sealing rings can meet the size and tolerance, and the sealing ability is very superior;

2. During manufacturing tungsten carbide sealing rings, some corrosion resistance rare elements are added to make the sealing ability better;

3. Tungsten carbide sealing rings are made of tungsten carbide, which have high strength and high hardness, impact resistance, and are not easy to deform.

Wear resistance, corrosion resistance, and thermal resistance are the most important basic requirements of tungsten carbide sealing rings. The raw material tungsten carbide has high hardness, wear resistance, strength, toughness, heat resistance, and corrosion resistance. Their high hardness and wear resistance can remain unchanged even at 500 °C. And at 1000 °C, the tungsten carbide sealing rings can retain high hardness.

Properties of tungsten carbide sealing rings:

1. Tungsten carbide sealing rings have some mechanical properties, such as tensile strength and elongation;

2. Tungsten carbide sealing rings have elasticity and hardness;

3. Tungsten carbide sealing rings can resist high temperatures and low temperatures. When the tungsten carbide sealing rings are put under high temperature, they will not decompose and soften; while under low temperature, they will not be hard;

4. Tungsten carbide sealing rings have good oxidation resistance and aging resistance, which can be used for a long time;

5. Tungsten carbide sealing rings have wear resistance and will not damage metal;

6. Tungsten carbide sealing rings are not easy to deform and are manufactured for different applications at low prices.
