Evaluate structural stiffness for piping stress analysis
Hydrocarbon plants use a system of pipes of various sizes, pressures and temperatures. Sometimes these pipes have pulsating flows that result in piping system vibration. These piping systems must be designed for a high degree of reliability, which requires a comprehensive piping stress analysis for thermal, sustained, occasional and dynamic loading conditions.
