deluge pipe line modification-

(OP)
there is a small modification in deluge pipeline (existing) .is it required to do hydraulic calculation again.as per nfpa what are the requirments

RE: deluge pipe line modification-

Read the nfpa code docs. They tend to be very prescriptive, but a common sense approach would be that unless the flow has increased by >10%, you don't need to re-do the analysis.

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