Cemented Tungsten Carbide Rings For Sealing Purpose
?
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)
Sintering
HIP.
The advanced computer-controlled HIP furnaces are applied to provide more pressure during the sintering process in order to get denser structure.
Powder
Excellent.
We carefully select and control the excellent quality of our raw powders. Powder spray drying technology ensures the uniformity of distribution of particles.
Processing
In house.
We offer customers a wide array of processing services on-site including centerless grinding, CNC cylindrical grinding, CNC internal grinding, wire EDM, and laser etching, etc.
OEM Custom Service
We can develop grades as per your requirement and make the same shape as your drawing. Laser marking and neutral package are also available for your benefits.
