API sets global benchmarks for pipeline design, ensuring safety and efficiency in oil and gas operations.
ISO standards promote international compatibility, enhancing pipeline reliability and interoperability.
ASME codes ensure robust construction, focusing on pressure integrity and material quality.
In order to distinguish different materials, it is generally marked with different colors, J55 with green, N80 with red, P110 with white
Oil casing is usually made of thicker steel and has some support structure to increase its stability; The tubing is usually made of a light steel pipe, the surface is smooth, the structure is relatively simple. The tubing looks relatively short, the upper part is cylindrical, the lower part is flat.
The materials of oil casing include ordinary carbon steel, J55, L80, N80, P110, 3Cr, 9Cr, 13Cr, 22Cr, 90SS, 95SS and nickel-chromium alloy.
Reduce material consumption, support and fixation, improve steel pipe rigidity, avoid hole collapse, isolate pollution sources, disperse pressure outside the well, improve toughness, in summary, oil casing plays a vital role in the process of oil exploitation, not only to ensure the safety of drilling and oil production, but also through various process improvements to improve their own performance and use efficiency
