K55 casing is mainly used in the well of water or petrol in the wall digging in order to support the drilling as well as the operation of the well. Therefore, oil casing pipe is a fundamental segment of oil well. While geological conditions are different in different places, the working condition is underground. To be specific, the mechanical state is complex, and the stress, bending and torsional may exert some influences on the casing pipe. This puts a very high requirement for the quality of the casing itself. Once the casing tube doesn't run well for some reasons, the whole oil or gas well can be destroyed.
