Tungsten Carbide Mechanical Seal Ring For Pump - China
price: 9.00 Dollar US$
Tungsten carbide is widely used as seal faces with resistant-wearing, high fracture strength, high thermal conductivity, and small heat expansion co-efficient.
It is the best material to resist heat and fracture in all hard face materials.
Tungsten Carbide Seal Rings are used as Mechanical Seal faces in pumps, Compressors and Agitators.
These are used in Oil Refineries, Petrochemical plants, Fertilizer Plants, and Drugs/Pharmaceutical Industries.
Mechanical seal rings are developed to withstand high temperature, high pressure & highly corrosive chemical attack.
we manufactures Rings in various shapes like Plain Ring, DA type, T-shape, L-shape and in shapes as per customers requirement.
Tungsten Carbide Rings are generally made with Cobalt as binder material.
Nickel bonded Rings also can be supplied as per following specifications.
Tungsten carbide ring for mechanical seal
Mediums to be sealed: water, oil, corrosion, other mediums including solid granule, Working environment: resisting abrasion, acid, alkali and erosion;
Working temperature: from -30℃ to 500℃
Application: pump, valve The material grade of tungsten carbide, material grade Density (g/cm3) Hardness (HRA) TRS Mpa
tungsten carbide + titanium + nickel 8 89HRA 1000
Material advantage: the usage life of our all material is better than the silicon carbide.
The price is similar with silicon carbide, but the transverse rupture strength is stronger, not easier to break when in the working.
