Prime features of zirconia ceramic seal ring:

1. Extraordinary wear resistance and excellent corrosion resistance in various harsh conditions

2. Ideal sealing performance because of superb low friction coefficient and similar thermal expansion coefficient as stainless steel.

3. Low wear loss can prevent the material of zirconia from the pollution of the fluid controlling system

4. Extremely long service life with minimum maintenance cost than various metal seal parts

5. High hardness, high flexural strength, high fracture toughness, high mechanical strength

6. Low thermal conductivity:  less than 3 W/m.k at ambient temperature, so it's an ideal thermal material

 

Description of zirconia ceramic seal ring:

Zirconia ceramic seal ring is a key part of the various pumps, valves in household appliances, electrical appliances, and industrial applications. It plays a decisive role in liquid, gas, oil sealing and controlling performance. 

With zirconium oxide ceramic outstanding properties, such as wear-resistance, chemical resistance, low thermal conductivity, high thermal expansion coefficient similar as stainless steel, very low friction coefficient, zirconia ceramic seal rings have been creating a very positive impact on aging features, service life-span, productivity, dependability in industrial equipment, mechanical engineering, like the food and beverage industry, medical equipment, electrical devices and so on.

Besides the ceramic seal ring, we also produce a variety of customized ceramic valve seat, ceramic ball valve, ceramic valve disc, ceramic piston and plunger for fluid, gas, oil-controlling / regulating system.

Packaging proposal and transportation solutions

1. We will keep the ceramic parts inside the inner package to be fixed without moving, then it will prevent them from collision each other,

to avoid any cause any chippings during transportation.

2. In addition, the inside of the outer carton will be filled with sufficient protective kinds of stuff.
