 Oil casing is a lifeline to maintain the oil well operation . Because the geological condition is different, stress state is complex, pull, pressure, bending, torsion stress effect on the pipe body, the casing itself quality put forward higher requirements. Once the casing itself damaged for some reason, maybe causing the entire cut back production, and even scrap.

  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 lsaw steel pipes and erw steel pipes which can not only improve product quality, but also save raw materials. Our products have high strength, good toughness and resistance to corrosion.
