Ceramic liner
 
1. Ceramic liner can be suitable for deeper oil reservoir, bad drilling geological structure environment, offshore oil and gas development.
2. The material of ceramic liners is the increased flexible zirconium ceramic. 
3. It is wear resistance, high anti-corrosion, high temperature resistance, high pressure, high intensity and high hardness. The using time of liners is up to 6,000 hours.
4. Zirconium ceramic liners have better performance than alumina ceramic liners such as more toughness, longer service life, saving water lubrication, reducing wear of piston.
