COMPUTATIONAL MODELLING OF A PIPE CONNECTORS

The aim of this project was to investigate and evaluate corrosion using computer modelling for investigating causes of failure on specimen which had similar behavior to nature of failures, used in petroleum industry. A nipple-connecter reducer made from malleable cast iron used to carry liquid and gas in a petro chemical company located in Bahrain was used as sample. The problem was also modeled to study the effect of the flow in causing the corrosion, in the nipple-connecter reducer assembly which concludes that the main cause of this attack is the flow turbulence, shear stress and pressure.
