Compared with silicon carbide sealing rings, cemented carbide sealing rings have more stable chemical properties such as good wear resistance, high thermal conductivity, low friction coefficient, small expansion coefficient, acid resistance, alkali resistance, self-lubricity, corrosion resistance, The advantages of high thermal conductivity and small expansion coefficient make it an ideal material for mechanical seals.
· The mechanical seal ring is used to seal the clearance between the rotating shaft and the stationary housing in equipment such as pumps and mixers so that liquid can not leak out through this clearance.
· Various types of tungsten carbide seal rings, such as Plain Ring, T-Shape, DA Type, Dace Seal Ring, L-Type.M7N, G60, and so on.
· Both standard and non-standard parts according to the customer's drawings or samples are all available from us.
· Material includes tungsten carbide-cobalt(WC-Co), tungsten carbide-nickel(WC-Ni)
The cemented carbide seal ring is made of tungsten carbide powder as the raw material, cobalt powder or nickel powder as the binder, pressed by a certain mold, sintered in a vacuum furnace or hydrogen reduction furnace, and made of high strength and high hardness cemented carbide material, which is not deformed and more compressive.
Tungsten Carbide Flat Seal Ring are widely used as seal faces in mechanical seals for pumps, compressors mixers and agitators found in oil refineries, petrochemical plants, fertilizer plants, breweries, mining , pulp mills, and the pharmaceutical industry. The seal-ring will be installed on the pump body and rotating axle, and forms through the end face of the rotating and static ring a liquid or gas seal.
As the most widely used mechanical seal products, cemented carbide seal ring has the characteristics of high hardness, wear resistance, corrosion resistance and so on.
Workers and techniques from Burray, have over 10 years of professional experience in the carbide seal rings; The professional sales team and after-sale service in carbide seal rings; We can provide an overall solution and select the most suitable tungsten carbide seal rings according to your application.
