piping stress analysis required?
(OP)
Hi all,
I am going to change out a section of corroded piping, since hotwork is not allowed thus I will go for "like for like" replacement with same new piping material but fittings component will be using "compression swaging" type fittings. Do I need to do piping stress analysis for this case?

What is the Operating pressure and temperature?
What is the commodity?
Why is Hot Work (welding) not allowed?
Please provide a sketch showing the configuration of the total piping system with a clear indication of what is the existing and what is the new piping.
Sometimes its possible to do all the right things and still get bad results

There are basically no changes on the configuration of piping, its just cutting out the corroded portion and change with new spool which is swaging type connecting to the existing, piping material remain the same, all pipe hangers and supports will be using the same.

Yes you are right, the size is for 3" and below, target instrument gas line.
