Piping with possible thermal expansion loop needed to pump suctions
Piping with possible thermal expansion loop needed to pump suctions
(OP)
Looking from a little advice from some piping engineers regarding a modification I would like to make to save labor and materials. During construction a feed line operating at 235degF and 30psig was designed with what appears to be a small expansion loop. I would like to remove the extra run and pipe straight to the center line of the split for the two pumps it supplies. I have included two ISOs and a 3d model I put together of how I would like the pipe to run. The material will be Hastelloy C276 Sch 40 8" pipe (SB-575 UNSN10276). My biggest concern is excessive strain on the pump suction inlets. I am not a piping engineer so I would love some advice!

These comments don't answer your question, but...
Perhaps the loop is there to avoid something/something that used to be there.
Are these all lap joint flanges? The symbology seems to indicate yes.
I hope those are not conical temporary strainers (witch's hats) downstream of the ball valves in FMP_3. If they *are*, check the length and which direction the cone is oriented and how you're going to remove it.
Should the eccentric reducer at the suction be bottom flat? Probably not.
