Prediction of Collapse Pressure of Submarine Pipelines in A Wide Range of Diameter-Thickness Ratio
China Ocean engineering, 2022 Submarine pipelines play an important role in offshore oil and gas development. A touchy issue in pipeline design and application is how to avoid the local collapse of pipelines under external pressure. The pipe diameter-thickness ratio D/t is one of the
