Tungsten Carbide Seal Download

We design and fabricate the tungsten carbide seal with high thermal resistance for the various applications of the industry. It contains high mechanical strength. The tungsten carbide seal is widely used for all hard face materials. The tungsten carbide is the ideal face material to resist the heat. It consists of high fracture strength. tungsten carbide seal is specially designed for the pumps handling fluids at high pressure. It provides uniform face loading.
