Good morning all.
Can you kindly assist with answers to the following questions?

1. What wall thickness would you use if you're doing analysis for a Cladded Pipe (ie. Carbon Steel cladded with Stainless Steel - both steels have different Yield Strengths)?

2. How do "Spring Constraints" behave? If you have a situation, where a nozzle is acting as a spring Constraint, what kind of Reaction(s) does it produce on the Piping System, how is it represented?

Regards

Read the specific code. It may say that you are not allowed to consider the cladding in your calculations.

1) Cladding is usually included as "weight only", therefore you can use the "insulation fields" for this.

2) You can check the [Nozzle] checkbox, which permits you to define the nozzle as either WRC297, API650, or PD5500. Each of these Codes or Bulletins defines how the stiffness of the nozzle is computed and used. CAESAR II will perform this computation and insert the appropriate flexibilities.
