API 5CT L80 Petroleum Casing Pipe
API 5CT L80 Petroleum Casing Pipe
Our API 5CT L80 petroleum casing pipe pertains to the second group of steel grade in accordance with the API 5CT standard. It can be divided into three models, including L80-1, L80-9CR and L80-13CR. Among them, the latter two models can adopt air quenching process.

As we all know, the API 5CT L80 petroleum casing pipe is the lifeline to maintain the operation of the oil well. The geological conditions are different and the underground force state is extremely complicated. All kinds of force make the comprehensive effect on the pipe body, such as tensile force, pressure, bending force, and torsional stress. All these reasons highly demand for superior quality of the casing pipe. Once this product is damaged due to some kind of reason, it will be possible that the whole well may appear the output reduction or even become scrapped. Thus, we spare no effort to produce the best product to ensure the security of every well.
