How to prevent the J55 ERW casing
from clasping and attaching, the hollow section of the API ERW sleeve, a large number of pipes used for conveying fluid, such as oil, natural gas, gas, water transportation, etc. The use of steel pipe manufacturing ring can improve the utilization of materials, simplify the manufacturing process, save material and processing time, such as rolling bearing rings, Jack suites, and so on, has been widely used in the manufacture of steel.
API ERW casing is mainly used for oil and natural gas drilling and oil and gas transportation. It includes oil drill pipe, oil casing and oil suction pipe.
The oil rig is mainly used to connect drill collar and drill bit, and through drilling power. The ERW casing is mainly used in the drilling process and completion wall to ensure the normal operation of the drilling process and the whole well after completion.
ERW casing is the lifeline for maintenance of oil well operation. Because of the different geological conditions and the complex stress state of the underground, the combined effects of the tension, pressure, bending and torsional stress of the pipe body are combined, which puts forward higher requirements for the quality of the casing itself. Once the casing itself is damaged for some reason, it may cause the whole well to be cut or even scrapped.
