The development of a computational tool for generation of high quality FE models of pipelines with corrosion defects

Abstract

Corrosion is one of the most common causes of accidents involving pipelines. Unfortunately, the semiempirical methods currently available are overly conservative for the assessment of some types of corrosion defects in pipelines. Fortunately, the computational simulations through finite element (FE) method are a very efficient and reliable approach to quantify the remaining strength of corroded pipes. However, the process of computational modeling demands intense manual labor from the engineer, and it is also slow and extremely repetitive, especially in cases of multiple defects. The main purpose of Technical Editor: Celso Kazuyuki Morooka.

Failure pressure prediction of corroded pipes under combined internal pressure and axial compressive force

“…automatic generation of models of pipelines with corrosion defects and automatic management of physical and geometric nonlinear analysis, respectively. The program and tools are described in various publications [1][2][3][4][5][6][7][8][9]. PIPEFLAW provides an interface easy to operate, reduction in the processing time of the analysis and accuracy and reliability for evaluating the integrity of corroded pipelines.…”
