Plants have a schedule for steam blow. And it will use temp and pressure lower than the design or operating. We have a designed springs, hold down guides, rigid hanger, etc.

So, you have a calculation, no up-lift, no overloads and the springs were okay. And when you connect the temporary pipe for steam blow and checked the report you saw something-for example your rigid hanger have an upward movements, and your springs were all affected too.

Are these okay for the supports during steam blow? Or they will remove other supports like rigid hangers for a whie if there's an uplift?
