Technological process of production of tungsten carbide seal rings: powder process → formula according to the use requirements → wet grinding → mixing → smash → dry → sieving → add binder → dry again → get the mixture after sieving → pelletize → pressing → forming → sintering → forming (blank) → blanks checking → end face grinding → cylindrical coarse grinding → internal fine grinding → cylindrical fine grinding → chamfering → grooving → polishing → cleaning → dimension check → packaging → entering warehouse.

Tungsten carbide seal rings are heavy to the touch and hard like silicon carbide. Due to high modulus of elasticity, these rings are suitable for high pressure applications, which prevent face distortion. It’s mainly used as mechanical seal faces in pumps, compressors and agitators. These are also used in oil refineries, petrochemical plants, fertilizer Plants, and drugs/pharmaceutical Industries.

Tungsten carbide seal rings generally made with Cobalt as binder material or Nickel as binder material. they are developed to withstand high temperature, high pressure & highly corrosive chemical attack. We can supply tungsten carbide seal rings in various shapes like Plain Ring, DA type, T-shape, L-shape and in shapes as per customers requirement.

When used, when choosing tungsten carbide grade, we should according to the working conditions to choose the right carbide grade, to meet specific application requirements.
