The invention discloses a pipe section crushing device and a test method thereof, and relates to the technical field of the pipe test. The pipe section crushing device comprises a base and a gland matched with the same; a holding slot is formed on an upper end surface of the base, and an upper holding slot is arranged on a lower end surface of the gland; the lower holding slot and the upper holding slot form a holding cavity after the base is matched with the gland; the holding cavity is used for placing a first cavity of the pipe section and a crushing airtight cavity located beside the firstcavity; a fixing module for fixing the pipe section is arranged on the base, and a displacement sensing module for detecting the pipe wall deformation of the pipe section is arranged on the base. Thecrushing device disclosed by the invention is simple in structure, the test can be performed by only intercepting a small pipe section; the pipe section crushing test is low in cost and capable of being operated at multiple occasions; the full-pipe section test can be performed without following the traditional crushing test way.
Description
technical field [0001] The invention relates to the technical field of pipeline testing, in particular to a pipeline section crushing device, and also relates to a pipeline section crushing test method. Background technique [0002] At present, due to the particularity of the marine environment and the complexity of offshore oil and gas production, submarine pipelines in low-temperature, high-pressure and highly corrosive marine environments not only bear static and temperature loads such as internal and external pressure, axial force, bending moment, etc. Combined action, but also bear the action of dynamic loads such as alternating external pressure, corrosion, waves, ocean currents, etc., so that the pipeline bears the combined action of various loads and causes multi-local buckling instability failure, that is, the collapse of the pipeline. [0003] Existing steel pipe crush resistance tests usually use devices such as pressure vessels and jacks, and most of them are bas...
