Ceramic liner
The advantage of ceramic cylinder liners are as follows:
- The Zirconium Ceramic cyliner liners can not only adapted to some tough environment such as deep oil reservoir,hard stratum and severe earthess,but also can be used for offshore oil and natural gas exploitation as well.
- Compared with Bi-metal liner,the service life of”DL” ceramic cylinder liner is 5-10 times higher.Its maximum and minimum service life can reach more than 4000 and 2000 hours respecticely
- The Zirconia ceramic cylinder liners which has used the phase transformation toughen technology has various advantages such as wear-resistance,erosion-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.
