Placement of pipe supports between flanges on a bobin spool 1

[Jramboii]

What are your thoughts on placing a single pipe support between two flanges of a straight run spool? Is this acceptable in terms of b31.1 guidlines and if so where can i refference this information.

Afaik the best practise is to place two supports to prevent a lever action putting strain on the flaged joints. I added a pencil sketch in case i was unclear on the issue.

Do the stress work.

The code won't tell you things like this.

Yes it will create some moments and forces on the flanges, but so what? They are big and strong and can usually take it.

But you need to do the analysis to confirm this.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

In addition to bolt strength, you might want to also evaluate the flanged connection for leak potential.

Reality used to affect the way we thought. Now we somehow believe that what we think affects reality.

The number and location of the required supports on the pipe spool may be determined by factors, such as material, pipe size, process condition, etc., as well as the allowable movement and moment of the equipment, i.e. vessel, pump, compressor, etc., the pipe connected to.
