A new hybrid approach model for predicting burst pressure of corroded pipelines of gas and oil

Accurate prediction of the burst pressure of corroded pipeline is of great significance to pipeline design, reliability analysis and maintenance decision. This paper presents a novel hybrid approach model for predicting the burst pressure of corroded pipelines. First, a new feature space with physical meaning is constructed based on the pipeline geometry, the size of corrosion defects, and the mechanical properties of materials. Then, a fusion …
