About us
Our companty is a professional instrument cable manufacturer integrating scientific research, manufacturing, sales and complete project. Long term commitment to the production and research of industrial automation instruments and meters, our company produced temperature instruments, pressure instruments, CNC instruments, standard calibration instruments, bimetal thermometer, liquid level transmitter, diffusion silicon pressure transmitter, intelligent differential pressure transmitter, integrated temperature transmitter, X series digital (light column) display.Oil casing is the steel pipe used to support the wall of oil and gas Wells to ensure the normal operation of the entire well during the drilling process and after the completion of the well. Each well uses several layers of casing, depending on the drilling depth and geology. Cement should be used after casing running. It is different from tubing and drill pipe, and can not be reused. It belongs to disposable consumption material. Oil casing is the lifeline of oil well operation. Due to different geological conditions, underground stress state is complex, tensile, compressive, bending and torsional stress act on the pipe body, which puts forward higher requirements on the quality of casing itself. If the casing itself is damaged for some reason, the entire well can be reduced production or even abandoned. Commonly used materials: according to the strength of the steel itself, the casing can be divided into different steel grades.
