Description
The ceramic liners can not only adapted to some enough
environment such as deep oil reservoir, hard stratum and severe
earthiness, but also can be used for offshore oil and natural gas
exploitation.
Compared with Bi-metal liner, the service life of “HC”
ceramic liner is ***0 times higher. Its maximum and minimum service
life can reach more than 4,**0 hours.
The Zirconia ceramic liner which has used the phase
transformation toughen technology has various advantages such as
wear-resistance, high-pressure-resistance,
high-temperature-resistance, high strength and high
hardness.
The cost of shipment, maintenance, labor and storage in
the drilling works can be reduced.
Compared with the Alumina liners, the Zirconia liners
have better toughness properties and longer service life. It can
also reduce piston wear and water consumption for
lubrication.
