Hello dears,

We want to analyze an under ground pipeline system, so I have some questions about this job. I was wondering if someone answer my question:

1- Someone said that the under ground but weld carbon steel pipe doesn't need to have anchor block. Is it correct?
2- I think under ground pipe doesn't need to have expansion loop. how about this?
3- Do we need to use any special supposition for analyzing such systems in CAESAR II?
