Product Description

Ceramic Injection Molding Square Zirconia Oxide / Zirconia Ceramic Tube

Benefits of zirconia ceramic tube:

1. Very high wear resistance, much higher 276 times than stainless steel

2. Higher density than most of technical ceramics, over than 6 g/cm3

3. Very high mechanical strength, hardness ver than 1300 MPa for Vicker

4. Heat resistance and can withstand higher temperatures up to 2400°

5. Very low thermal conductivity, less than 3 W/m.k at room temperature

6. Similar coefficient of thermal expansion as stainless steel

7. Exceptional fracture toughness reaches up to 8 Mpa m1/2

8. High chemical resistance, aging resistance and not rust forever

9. Resistance to molten metals due to an extraordinary melting point

Description of zirconia ceramic tube:

We manufacture a wide range of dimensions zirconia ceramic pipe from OD2mm to OD100mm in different grades of zirconium oxide

All these zirconia ceramic pipes offer high fracture toughness, high wear resistance, corrosion resistance, low thermal conductivity and so on.  So zirconia ceramic pipes can be used in various severe service conditions.

Many of these zirconia ceramic pipes are used in precise assembly devices, like a ceramic plunger, sensor parts in automation, ceramic cup ring for oil printer, so further precision processing is needed via fine grinding, CNC machining and polishing. With in-house comprehensive types of equipment, we are capable of control the critical parameters very well.
Besides zirconia ceramic pipes, we also manufacture a wide range of ceramic valve seat, ceramic plunger, ceramic wire guides and various complicated zirconia structural ceramic parts.


Application of zirconia ceramic parts:

1. Precision ball valve (balls and seats)          2. Pump seals, valves and impellors     3. High density grinding media
4. Oxygen sensors                                          5. Thread/yarn/wire guides                    6. Fuel cell membranes
7. Cutting blades                                             8. Radiofrequency heating susceptors     9. Medical prostheses
10. Metrology components

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.
