System : Line connected with top nozzle of column.

1) What are the maximum possible steam out cases to consider in analysis for conservative side, if no information available at FEED stage of project.


2) What are the good engineering practice for steam out conditions ?

My opinion:

1. Check with your project whether piping is isolated from Equipment during steam out. From that you can figure out conservative conditions.

2. This question is too general. Stress analysis should be treated as normal. Follow common practice for piping layout around column.
