Allows the pipe to expand and contract due to temperature changes without damaging connected equipment (pumps, turbines, vessels). If you share with third parties, their policies apply
Complete fixity points that restrict all six degrees of freedom (three translational, three rotational). They isolate highly stressed piping systems from sensitive machinery.
Act as hydraulic or mechanical shock absorbers. They allow slow thermal movements during normal operations but lock up instantly during high-frequency dynamic events like earthquakes or relief valve trips. 5. Compliance with Piping Codes and Standards
Layouts must provide headroom and clearances for removing equipment internals like exchanger bundles or pump shafts. Allows the pipe to expand and contract due
If the stress PDF shows an operating displacement > 1 inch at any support point, you specified the wrong support type. Change it to a variable spring, then re-route to eliminate the spring in Revision 2.
The root of most stress problems is a lack of flexibility . The purpose of a piping flexibility analysis is to produce a layout that causes neither excessive stresses nor excessive end reactions on connected equipment.
The document you are looking for, Fluor Piping Design Layout Training Lesson 1: Pipe Stress heat exchanger tube bundles).
Your pipe stress engineer will output a PDF marking three failure modes. Here is how your layout directly causes or prevents each:
Valves, instruments, and flanges must be easily accessible for operators. Pipes should not block access to equipment maintenance (e.g., heat exchanger tube bundles).
