OEM ODM Tungsten Carbide(TC) Mechanic Seal Rings / Carbide Seal Faces
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.
The two most common variations of tungsten carbide seal faces/ring are cobalt bound and nickel bound. the seal faces/rings of Nickel bound tungsten carbide is more corrosion resistant although the seal faces/rings of the cobalt bound tungsten carbide is more than adequate for most services. Neither is as good as alumina. a tungsten carbide seal face/ring has a very high compressive and tensile strength,a high modulus of elasticity. The mechanical seals with tungsten carbide seal faces or rings can be used in pumps operating in fluids with sands or solids.
Some grade for tungten carbide sleeve for reference
| Grade | Density (g/cm3) | Hardness (HRA) | Toughness (N=mm2) | Chemical Composition | Performances & Applications |
| 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. |
| 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 |
| 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% |
Five essential elements of tungsten carbide products
1.high hardness
2. high corrosion resistance
3. strong abrasion resistance
4.long service liftime
5. high bending strength
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
