Liner
Eastland offers zirconia liner, hy-chrome liner, chrome-plated liner and hardened liner matched performance and durability for in most drilling conditions.
Hy-chrome Liner
Eastland’s hy-chrome liner is made with a over 27% chrome iron inner sleeve in a forged steel outer shell. The bore hardness is 60 to 65 RC while the hull has high tensile strength of more than 90000psi. All hy-chrome liner are manufactured with an “HP” lip in case of inner sleeve slippage.
The service life of this liner is more than 800 hours under normal drilling conditions. Eastland’s hy-chrome liners are made for superior performance under tough corrosive and abrasive conditions.
Zirconia Liner
Zirconia liner(ZrO3) combines the strength of a forged steel outer shell with the abrasion and corrosion resistance of a ceramic inner sleeve. Zirconia liner is designed to adapt to deep oil reservoir, hard stratum and severe earthiness, offsore oil and natural gas exploitation. The service life of this type liner is over 4000 hours. Compared with hy-chrome liner and Alumina liner, zirconia liner possesses better impact strength, higher hardness with wear resistance, stronger erosion resistance, higher pressure resistance and finer surface finishes.
