Description

Technical field [0001] The present invention relates to the field of pipeline detection, and more particularly to a method and system for calculating a small-diameter pipe strain based on internal detection. Background technique [0002] Due to the characteristics of the long-in-oil pipeline, it is often caused by some geological conditions unstable region or natural disaster zone, which causes a large lateral displacement, deformed, thereby generating a large bending strain in the pipe body, and causes the pipe loss when severe Stable or material damage. Since the tube body at a local curved strain caused by natural disasters In addition to the normal internal pressure load, it also withstand the bending stress load attached to the curved strain, so the presence of the pipe curved strain severely affects the structural integrity and operation safety of the pipeline, especially It is more likely to cause pipe failure when there is severe defects where the bending strain is exist....
