product information

Carbide seal ring use tungsten carbide powder as raw material, adding suitable amount of cobalt powder and nickel powder as
binder, through a certain mold pressed into the ring, and finally sintered in the vacuum furnace or hydrogen reduction furnace.
Tungsten carbide seal rings are the most basic material in friction materials, and they are widely used as essential components of
seals. In addition, the seal rings is also widely used in the petrochemical industry due to its excellent wear resistance and
corrosion resistance.

Tungsten carbide seal ring face is a very versatile seal face used for mechanical sealing. It is a circle where rotary and stationary seal ring contacts, so that liquid won't leak out through. It widely used for Pumps, Compressors, Agitators, Oil Refineries, Petrochemical plants, Fertilizer Plants, and Medical Industries.
