Flexibility Analysis of Refinery Piping System
Abstract: Piping systems in downstream refineries and process plants experience a great thermal strain due to the difference between ambient and operating temperatures of process and utility fluid flowing through them. This thermal growth causes thermal stresses which leads to failure in piping components like flange leakage, deflection in piping, fractures at nozzle juncture and other fatal errors in piping system. Therefore, these piping structures must be flexible enough to support …
