Waterhammer analisys its obligatory ?
(OP)
There exists any code asme? api?, i know that it depends of the situation, but i would like to know when its extremely necessary, if its critic?
Best regards for all,
Cesar.

E) Sources of pressure to he considered include ambient influences, pressure oscillations and surges, improper operation, decomposition of unstable fluids, static head, and failure of control devices.
In my mind it means that if the waterhammer analysis limits/defines the design envelope then it is obligatory.

Its not _always_ that simple

GIGO pays the bills.

Estimate water hammer loads in steam piping
The Problem is more complicated because of the two-pahses flow.

Before a project of a line of pumping to be constructing, how to determine if it is necessary or not to study the transitory phenomena (known normally with the name of "water hammer"?
The first thing that must be done is to calculate the pressure in regime that supports the pipeline.
Then Jucowski's pulse must evaluate of overpressures, that is the maximum value that the same one can adopt. Later, the pressure is evaluated in regime(diet) + - the pulse and is observed if it comes to dangerous values for the break of the pipeline (to see specifications of the same one) or minor values to-6 to-7 m of water column to avoid cavitation in the whole pipeline. Of being near these limits in some case it suits to study with more detail the system
