IMHO, Simplify it.

No, better to scrap it.

What purpose do the springs have, given that the turnbuckles appear to prevent the pipe moving vertically ?

What does the arrangement actually achieve ? Are the springs to be removed ?

IF you really want to use such a wierd design, consider this:

How far does the pipe move axially ?

Do you really need to include all those links in an analysis model ?

You might be ok modelling a transverse guide alone, in addition to the spring units (or vertical support if removed). That would make some sense at least.
