Equivalent static pressure for piping

Equivalent static pressure for piping

Equivalent static pressure for piping

(OP)
Hi all, I was wondering if there is a way to calculate the stresses a cylindrical section of piping would experience based on a sudden increase in pressure.

Normally if you have the dimensions of the piping (Diameter D, thickness t) and a design pressure P, you can get the following stresses:

Hoop Stress = PD/2t

Longitudinal Stress = PD/4t

However say I only have how much the pressure increased by in a given time such that I have a rate in psi/hr. Is there a way to convert this to be used in the above formulas? Or is there a similar set of equations used for those in impact stresses ?

Are you trying to do a water hammer analysis?

RE: Equivalent static pressure for piping

(OP)
No water hammer.

The question was in relation to an event where there was a sudden overpressure of a vessel via some piping within the vessel designed to B31.3. And I wanted to know if there was a way to ascertain if there would have been possible damage to the piping to warrant opening the vessel.
