Advantages:

1. Good oxidation resistance: Sliding sleeve with Si3N4 material have good oxidation resistance and can be used in high temperature environment for a long time

2. Good thermal conductivity: the thermal conductivity of Si3N4 ceramic sliding drivepipe is very high, which can transfer heat energy quickly and reduce the temperature of friction parts.

3. High density: The density of silicon nitride ceramics can reach 3.2g/cm³, which is stronger than ordinary ceramic materials.

4. Good corrosion resistance: Sliding sleeve with Si3N4 material have strong acid and alkali resistance, high temperature resistance and corrosion resistance, can be used in harsh working environment for a long time.
