Ceramic Liners features:
-
Corrosion-resistant, acid-proof alkali, heat-resistant, it can work in the medium of the drilling mud or other corrosive liquid etc.
-
High hardness, wear resistance, it can resist high pressure mud of sharp or abrasive resistance of the solid particles grinding or scour, such as rock debris,quartz sands,iron ores,scrap iron.
-
Evenly distributed structure for microstructure and smoothly surface will improve the life of the piston.
-
Working pressure is high, more than 52 MPa (7500 PSI), to meet drilling deep well, ultra-deep demand. Its maximum and minimum service life can reach more than 4000 and 2000 hours respectively.
Ceramic liners material and performance index:
Ceramic liner take zirconia composite formulations as the formula. The composition of zirconia: 5.4% yttria and 94.6% zirconia, the average particle size less than 0.5 μm. Massive experiments show that the toughness is maximum when 80 90% zirconia is added.
