... are used as the basis to develop the correction factor as a function of the corrosion defect sizes and magnitude of the longitudinal compressive stress. The proposed model is validated by a large set of parametric FEA and full-scale burst tests reported in the literature and is shown to provide marked...

...Jie Zhang; Hao Zhang; Xiaohua Chen; Chunyu Yu Corrosion and erosion are the main factors of pipes failure. Erosion wear characteristics of elbow pipe with corrosion defect are investigated in this paper. Initially, the erosion result of nondefect elbow pipe is calculated and compared to elbow pipe...

... (type 1), but it occurs on the central part of both the outer surface defect (type 2) and the double defects (type 3). The appearance of defects greatly weakens the stability of the pipeline. For equivalent sum total corrosion defect depth, a single defect is more harmful to the pipeline than double...
