Why Selecting Tungsten Carbide Sealing Ring for Special Working Medium?

Why Selecting Tungsten Carbide Sealing Ring for Special Working Medium?

Tungsten carbide sealing ring is a ring seal, mainly by being pressed after the elastic and tight in the static parts of the inner hole wall sealing role. With wear resistance, corrosion resistance and other characteristics. Tungsten carbide powder, cobalt powder and other materials, after ball milling, mixing, drying, sintering and other processes prepared.

Generally, different working media have different requirements for sealing. Under what circumstances, we will choose cemented carbide sealing ring?

Such as polymerization, furfural, formaldehyde, ethylene, vinyl chloride monomer, acrolein, vinyl acetate, formaldehyde, such as water, raffinate by friction heat and stir the heat temperature rise, when the temperature rises to a certain cause aggregation, so we should pay attention to keep the temperature does not exceed the polymerization temperature, ensure sufficient cooling, end use hard material, ZUI good using two sealing, improve sealing fluid volume, Enhanced cooling, tungsten steel ring to prevent excessive corrosion.

Because the cemented carbide seal ring has good hardness, high hardness, good wear resistance, high elastic modulus, high strength and good chemical stability, low impact toughness, low expansion coefficient, features, can solve problems such as hot cracking of mechanical seal ring, the energy efficiency so general advise clients special working medium choice carbide seal ring.
