Combining the advantages of forging overcoat resistance to wear and high chromium wear-resistant anti-corrosion than that of national standard.70 percent of liners sold to united states¡¢russia¡¢menggu¡¢kazakhstan and in the middle east.
¡¡¡¡for satisfying the need of oil field drilling and reducing drilling cost, our company manufacture jytd-10 3/4*5 1/2-21 simple casing heads for many years experience. ¡¡¡¡usage: Connecting outer pipe thread directing to the surface casing pipe thread in the drilling operation. The casing weight in addition to the surface casing can be hanged by the hanger. ations, for example, remedial cementing from the side of the hole and hiting fluid into the side of the hole to to balance the internal pressure at acid-fracturing.
It is controled by hydraulic to reach seat hanging. Working with sq seting-ball carrier, it is suitable for applications in horizontal and highly-deviated wells. Sealing element is made of nitrle/fluorine rubber and its temperature can reach 120¡æ/200¡æ. Main parts are fabricated with high-strength alloy steel providing high resistance
