Nonlinear analysis of buckling behavior and ultimate strength of a corroded pipeline under hydrostatic pressure (with ANSYS)

Abstract

Spillover of hazardous materials from transport pipelines can lead to catastrophic events with serious and dangerous environmental impact, potential fire events and human fatalities. The problem is more serious for large pipelines when the construction material is under environmental corrosion conditions, as in the petroleum and gas industries. In this way, predictive models can provide a suitable framework for risk evaluation, maintenance policies and substitution procedure design that should be oriented to reduce increased hazards, and also finding and introducing methods which help in inspection and maintenance of oil and gas pipelines seem mandatory.In this project, various failure due to corrosion in oil and gas pipelines are predicted and there are models using finite element method, modeling which helps in inspection and maintenance of oil and gas pipelines. The models released are designed, tested and evaluated with Ansys software. These models investigate different kinds of oil and gas pipeline and do predict the failure of them, failure which can occur because of rupture, fatigue and corrosion.
