(OP)
How to model heaters, pumps, valves, flanges for piping stress analysis and what except that the full restrained to be modeled is appropriate for pumps and heaters. What to do with valves except than put their weight?





RE: componenets in piping stress analysis and design
Equipment and components such as valves need to be modelled in a stress analysis using a combination of rigid and flexible elements as required, to represent stiffness, weight and its thermal expansion. Then you must also consider fixity ... for instance a pump base is usually, but not always, anchored.
Valves are normally modelled simply as a rigid body with a defined mass. If you are doing a modal or dynamic analysis you might need to include the valve stem and / or actuator as a specific component.
