The ceramic liner is made up of a metal shell and a high-wear-resistant ceramic lining which are fitted together through mechanical processing and hot charging. It is mainly used in offshore & onshore drilling and geological exploration. It has the properties of high strength, high toughness, wear resistance, high hardness, corrosion resistance, acid and alkali resistance, anti-static and super smooth surface, suitable for use in particularly adverse circumstances.
Features of Ceramic Liner
● Wear Resistance:
Compared with the traditional bi-metal liner, ceramic liner’s service life is 10 times longer and can be up to 4,000 hours.
● Surface Quality:
The ceramic lining has uniform microstructure. The surface undergoes rounds of fine machining and has excellent smoothness and gloss.
● Mechanical Properties:
By using the phase transformation toughening technology, the strength, hardness, toughness and thermal shock resistance of the material have been greatly improved, thus endows it with superior overall mechanical properties.
● Lower Costs:
Compared with the traditional bi-metal liner and single-phase alumina liner, the costs of the ceramic liner such as maintenance, labor, storage, transportation etc. are much lower.
