1. Corrosion-resistant, acid-proof alkali, heat-resistant, it can work in the medium of the drilling mud or other corrosive liquid 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 micro structure and smoothly surface will improve the life of the piston.
4. 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.
