Petroleum casing pipes can be divided into different steel grades according to the strength of the steel itself, namely J55, K55, N80, L80, C90, T95, P110, Q125, V150, etc. Different well conditions and depths have different steel grades. In corrosive environments, the casing itself is also required to have corrosion resistance, and in places with complex geological conditions, it is also required to have anti-collapse performance.
Read MoreDifferences Between Seamless Casing and ERW Casing
According to the manufacturing method, the steel pipe can be divided into two categories: seamless steel pipe and welded seam steel pipe. Among them, ERW steel pipe is the main variety of welded steel pipe. Today, we mainly talk about two kinds of steel pipes used as raw materials for petroleum Casing pipe: Seamless casing and ERW casing.
