The extent of plastic deformation of the linear part of the pipeline

An analysis of developments in recent years accidents showed that the main reasons why there have been sudden destruction of sites of pipelines are shortcomings of the design and as-built documentation, as well as plastic deformation. This article discusses the use of fuzzy logic to evaluate the plastic deformation of the linear part of the pipeline this research was obtained by the ratio of the maximum allowable stress values of the linear part of the pipeline during plastic deformation at the fuzzy input parameters (the present case - the internal pressure).
