If you have two points restricting the pipe in the same direction, it can not move .... you need to change the design.
See the basic rules of piping flexibility.

I am involved with a new project using european normative EN-13480.
My question is about the right cases combination based on thermal stresses.

I know exist a very long discussion about these, but can somebody explain to me detailedly this?
For example:
Can I temporarily delete the supports in the sus case when I have lift off?
Thanks.

Friends, thanks for your answers, the problem is very big now because the client want to use crosses (very crazy) in your project (delayed coker) for cleaning lines.
I find information about SIF in an old paper, and in conclusion is possible to use SIF of normal TEE x 1.5 that they tell me...
I verified all the calculations of Caesar and it uses the internal diameter, I used a simple excel sheet, and the results of Caesar are "ok" in comparison with NEMA 23.
If we considerate the internal diameter the result it is more conservative.
But, textually NEMA says:
Dc = Diameter (in...
Thanks ApC2Kp, I have a new ask...
Caesar II use for calculate Dc factor the nominal diameters, but I understand that, according to that mentioned in NEMA 23, should be calculated with internal diameters.
Please, can somebody clarify this?
Regards.
I calculate moments and forces resultants for comparate with Cesar 5.1 NEMA 23 Module.
The loads and Dc factor are ok, but my problem are the moments.
I don't know as Caesar it calculates this.
I calculate using the considerations included in NEMA 23.
I use translations force from other...
I want to outline a discussion about the trunnions installation in elbows using Caesar.
They are very well-known the methods of verification of stress in trunnions (for example using the Kellog method), but this items aren’t the main thing in this discussion.
I understand that in many cases...
