NFPA 14 and grooved joints

NFPA 14 and grooved joints

NFPA 14 and grooved joints

(OP)
We could not find any reference to grooved joints in piping in NFPA 14.

¿Are they allowed as a piping joining method in non sprinkler protected spaces?

RE: NFPA 14 and grooved joints

NFPA 14-2013 4.4.3 Groove Joining Methods

4.4.3.1 Pipes joined by grooved fittings shall be joined by a listed combination of fittings, gaskets and grooves.

Good to go.

Thanks for the information.

NFPA 14 requires protection of piping in enclosing with same fire rating as stairway enclosure.
