Ceramic cylinder cover

* Applicable to the rig123.net' target='_blank'>drilling and mining environment with deep petroleum reservoirs and poor geological structure, as well as offshore oil and gas development.

* 5-10 times longer life than double metal cylinder liners. The service life can reach more than 4,000 hours.

* The zirconia ceramic cylinder liner developed by phase transformation toughening technology has excellent wear resistance, corrosion resistance, high temperature resistance, high pressure resistance, high strength and high hardness.

point.

* Reduce the transportation cost, maintenance cost, labor cost and storage cost of drilling work.

* More toughness, longer life, more lubrication water and less piston wear than alumina ceramic cylinder liners.
