Our grade P110 oil well drilling casing pipe always works under harsh environment, which needs to withstand the horribly large loads. Thus, the demand for the comprehensive mechanical properties of this material is extremely high. Our product utilizes the P110 steel grade material with the molybdenum content range from 0.15 to 0.25% and the chromium content of 0.80 to 1.10. After the hardness test, tensile test and some others, it possesses stable performance, good hardness, as well as ultra high tensile strength and yield strength. In addition, our product can provide high dimensional precision, convenient installation and operation, as well as uniform and compact internal organizational structure. During the packaging process, the protection ring should be screwed on the exposed part of the thread of each casing pipe and its coupling so as to safeguard the thread.
