Anti-corrosion oil casing pipe
L80 13cr petroleum casing has higher anti-corrosion performance at a certain low temperature state. After increasing the temperature, the anti-corrosion performance will decrease. As the temperature rises, the anti-corrosion performance will also improve. The corrosion resistance is much better. According to different temperatures, through different experiments and improvements in China, L80-13CR and higher steel grade P110-13CR Super 13cr have been developed to control the Cr content in the range of 12% -18%
