Resistant-Wearing Tungsten Carbide Seal Ring Mechanical Parts
Tungsten carbide is widely used as seal faces with
resistant-wearing, high fracture strength, high thermal
conductivity, small heat expansion co-efficient. It is the best
material to resist heat and fracture in all hard face materials.
Five essential elements of tungsten carbide priducts
1.high hardness
2. high corrosion resistance
3. strong abrasion resistance
4.long service liftime
5. high bending strength
Some grade for tungten carbide sleeve for reference
| Grade | Density (g/cm3) | Hardness (HRA) | Toughness (N=mm2) | Chemical Composition | Performances & Applications |
| YG6 | 14.9 | 89.5 | 2150 | Co 6% | Good Wear resistance, used for hard wood,processing original wood,
aluminum section bar,brass rod and cast iron
|
| YG8 | 14.6 | 89 | 2320 | Co 8% | Suitable for the roughening of cast iron and light alloys and also
for the milling of cast iron and low-alloy steel.
|
| YN6 | 14.8~15 | 90.5 | 2100 | Ni 6% | This grade nickel binder, non-magnetic, it has good wear resistance
& corrosion resistance performance, especially used for high
pressure environmental |
| YN8 | 14.2 | 91 | 2300 | Ni 8% |
| YN12 | 14.2~14.4 | 86.5 | 2250 | Ni 12% |
Features of tungsten carbide seal ring :
1. Tungsten carbide rings are the most wear resistant rings
available on the planet.
2. Tungsten is about 10 times harder than gold, 5 times harder than
tool steel, and 4 times harder than titanium.
3. Due to their extreme hardness, tungsten carbide rings will hold
their shapes and shine longer than any ring on the market.
4. Carbide rings have been referred to as the "Permanently polished
rings".
5. Carbide rings will NOT bend.
The Application of tungsten carbide seal ring :
The cemented carbide seal-ring can be divided into both of the
kinetic seal-ring and static seal-ring, and constitutes mechanic
seal together with the spring, rubber seal-ring and steel jecket.
It will be used mainly for waste water pump, water discharge pump
for the mines, centrifugal pump, centrifuge, slag slurry pump and
slurry pump in the adverse working conditions of high speed
rotation, sand flush abrasion and corrosion. The seal-ring will be
installed on the pump body and rotating axle, and forms through the
end face of the kinetc and static ring a liquid or gas seal.
We can supply various kinds of tungsten carbide rings , such as
dynamic and static rings , the dynamic and static ring is also
named sealing rings used for mechanical seal and it also suitable
for the equipment which's grinding medium between 0.2 and 0.6mm ,
grinding & dispersing size between 100 and 500mm
