What is zirconia liner?

Zirconia liner is made of zirconia(ZrO2) material inner sleeve and steel material outshell.

Zirconia liner can offer lifetime cost savings, significantly longer service, better performance and safer operation than sleeves made of more commonly used chrome iron or alumina ceramic.

What’s the advantages of zirconia liner?

A.   Piston Wear

The special hardness and exceptional wear resistance of zirconia translates into longer service from the urethane and rubber pistons that move at high speeds and under tremendous pressure inside the mud pump liners. With true bores and zirconia liners honed to a fine 4 RMS finish, piston wear/consumption can be reduced by as much as 75%.

B.   Labor and Rig Downtime

Eastland’s zirconia liners ave service lifetime over 4000 hours which can reduce the labor cost during the fluid end expendables replacement and rig downtime. The costs cannot be forecast in event of breakdowns, emergencies or that are mud pump liner-related.

C.   Other Considerations

All drilling operations require a plentiful and continuous flow of water to minimize heat build up that could burn up pistons and/or cause bore wear. Use of a zirconia liner does not require any alteration of the driller’s existing lubrication system, unlike an alumina liner that requires a larger water supply.
