What size is the pipe?

What is the wall schedule is the pipe?

What Material is the pipe?

What is the maximum operating temperature is the pipe?

How long is the run of pipe (from direction change to direction change)?

What is the spacing of the pipe supports?

What kind of pipe supports are they (Steel column/beam, Concrete, what)?

With this information someone out here should be able to offer some help

Yes, more information is required -

and please, what exactly do you mean by 2d/3d?

(piping stress design is not as easy as it "appears" - I suggest readind a couple of books if you were really interested - the first one being "Introduction to Pipe Stress
Analysis" by Sam Kannappan)

If you would like more book recommendations - please ask.

Digging further - I have discovered a pretty exhaustive list of piping books:

http://www.amazon.com/Piping-Stress-Analysis/lm/R19QVFW37HMWND/ref=cm_lm_byauthor_title_full

Plus there are some more that are missed - namely:

Grinnell's "Piping Design and Engineering"
