Ceramic Liner , High temperature insulation wear-resistant for mud pump , for oilfield
Description:
The ceramic liners cannot adapted to some tough 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 working time of HC ceramic liner is improved 5-10 times. the average working time is 4000-10000 hours, the minimum time is 2000 hours at least.
The Zirconia ceramic liner which has used the phase transformation toughen technology has various advantages such as wear- resistance, erosion - resistance, high- presure-resistance high-temperature-resistance,
high strength and high hardness.
The cost of shipment, maintenance, labor and storage in drilling works can be reduced.
Compared with the Alumina liners, the Zirconia liners have better toughness properties and longer service life, it also reduced piston wear and water consumption for lubrication.
Ceramic liners for drilling mud pump are widely used in Coal, Non-ferrous metal, drilling field to improve drilling efficiency.
