Dynamic loading on pipe supports
Dynamic loading on pipe supports
(OP)
I am looking for information on how to determine the magnitude of additional loads (besides the dead load of water filled piping) that would be imparted to a normally dry piping network. Specifically, on a fire protection deluge system, how do you determine the loads that cause the piping to "jump" when suddenly charged with water?

Regards to the deluge system analysis look at the following engineering tools CAESAR II, FE-PIPE, BOS FLUIDS.
A detail Piping Classification Specification is required and verified calculation for the Pping Classification.
Have a real good look at the engineering manual on Ameron International for deluge system www.ameron.com

Additionally, would the only force applied to an external support be due to slug flow? I am thinking that the stresses developed due to water hammer, etc. would be restrained by the piping walls and fittings and not transferred to supports. Am I totally off base?
The specific problem at hand is a fire protection deluge system ring header supported off pipe stanchions. We have designed several such systems where the ring header is located several feet above a floor. When the system discharges, the piping loop shakes initially (as expected), but no failure is experienced. However, when the approving authorities see the system shake, they want these shaking forces accounted for in a structural calculation.
Recent additions of NFPA 15 (National Fire Protection Associations Standard for Water Spray Systems) offer guidelines for sizing such pipe stands, but it appears as if they are only sized for the load due to water filled piping, not dynamic loads.
Being a sprinkler system designer, I don't have access to any of the pipe stress analysis software recommended earlier, but if slug flow is the only significant contributing force, I think I can do hand calcs to approximate such loading.
Any suggestions?
