Double Metal API Standard Cylinder Liner

1.Forging Drilling Tools Suitable for deep oil reservoir, hard stratum and severe earthiness, offshore oil and natural gas exploitation.

2.High density Drilling Tools work life is 2000 hours, could reach 4000 hours normally.  5-8 times longer than bi-metal liner.

3.API Cylinder liner Wear-resistance, erosion-resistance, high-pressure-resistance, high-temp-resistance,high strength and high hardness. 

4. Reduce the cost of shipment, maintenance, labor and storage in the drilling works.

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 microstructure 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.
