Oil casing is a lifeline to maintain the oil well operation

　　According to the strength of steel casing can be divided into different steel grade, namely J55, K55, N80, L80, C90, T95, P110, Q125, V150 etc. Well condition, well depth is different, with different steel grade,also requires the casing itself has corrosion resistance in corrosive environment . In the complicated geologic condition place also requires a cannula having a anti-collapse performance.

　　We have adopted advanced production equipment and technologies to manufacture our carbon steel pipe fitting and steel flange which can not only improve product quality, but also save raw materials. Our products have high strength, good toughness and resistance to corrosion.
