Abstract

The invention relates to a testing machine for simulating the fatigue life in a full scale mode in the marine environment of a harbor pipeline, and the testing machine belongs to the technical fields of new pipeline material development and structure design and mechanics performance testing, wherein two guide rail beams are fixedly connected with a workbench; two movable supports are respectively in sliding connection with the guide rail beams; two servo loading units are respectively in sliding connection with the guide rail beams; and an internal pressure loading unit is fixedly connected with the workbench. The testing machine provided by the invention has the advantages that the performance of the harbor pipeline is comprehensively and reliably analyzed; the loading type of any combination is realized; the mechanics performance, welding performance, fatigue life and the like of the pipeline are tested more comprehensively and more accurately by simulating the stress conditions of the harbor pipeline in a full-scale and full-direction mode; and the testing machine has important significance in effectively preventing the harbor pipeline from fracturing.

Description

technical field [0001] The invention belongs to the technical field of pipeline new material development, structural design and mechanical performance testing, and is especially suitable for testing mechanical performance, welding performance and fatigue life of full-scale sea service pipe sections or welded pipelines. Background technique [0002] At present, in the strategic research of long-term domestic science and technology planning, the research on oil and gas has been highly valued by the state, and the general policy of "adjusting the east, developing the west, and speeding up the sea" has been put forward. Now the development of offshore oil and gas has basically taken shape The development of high-speed and high-efficiency has become a new economic growth point. Submarine pipelines are the key connecting components of oil and gas transportation, and their construction volume is increasing year by year. While the submarine oil and gas pipeline continues to extend, ...
