Tungsten carbide(TC) mechanical seal rings or faces

Products Mode: tungsten carbide/TC mechanical seal ring/face
Attributes
tungsten carbide seal face: as a mechanical rotary seal face
TC seal face: as a mechanical rotary face
Tungsten carbide(TC) is widely used as seal faces or rings with resistant-wearing,high fractural strength,high thermalconductivity, small heat expansion co-efficient.It is the best material to resist heat shock in all hard face materials.Lapping and polishing is very important to mechanical seal faces/rings.The mechanical seal faces/rings touch the grinding wheels with grinding compounds  in a moving way, The high precision can be obtained by the way of removing a extremely thin surface of mechanical seal faces/rings. The lapping and polishing improve the organizations of mechanical seal face surface and create a seal face surface to resist friction. Lapping and polishing makes the friction of seal faces smaller and promotes the surface energy and the resistance to corrosion and the polish

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.
