Product Introduction
Oil casing is mainly used for oil and gas well drilling and oil and gas transmission. According to the strength of the steel itself, the casing can be divided into different steel grades, namely J55, K55, N80, L80, C90, T95, P110, Q125, V150 and so on. Different well conditions, well depth, the use of steel grades are also different. In the corrosive environment, the casing itself is also required to have corrosion resistance. In the place of complex geological conditions, it is also required that the casing has the performance of anti-collapse.
