1) Corrosion-resistant,acid-proof alkali, heat-resistant, it can work in the medium of the drilling mud or other corrosiveliquid etc.
2) 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.
3)Evenly distributed structure for microstructure and smoothly
surface will improve the life of the piston.
4) Working pressure is high, no more than 52 MPa (7500 PSI),
to meet drilling deep well, ultra-deep demand.
