1.Tungsten carbide represents a versatile seal ring material that is broadly applied in all acidic environments.
2.It is generally the material of choice in applications where distortion due to high pressures or rapid wear in abrasive environments are modes of premature failure.
3.Tungsten carbide seals possess a unique combination of high fracture strength and high hardness that minimizes or eliminates these problems.
4.Other favorable properties of tungsten carbide seals include high thermal conductivity values and low coefficients of thermal expansion. These kinds of seal rings lifetime more than other material.
5.These characteristics promote the efficient removal of heat and provide dimensional stability at higher operating temperatures.
