Friction loss of grooved coupling joints
Friction loss of grooved coupling joints
(OP)
Hello Everyone,
I've a question about jounts. In particular about grooved joints. Is there something written in the NFPA13 about this.
And if so; what value is recommended for the friction loss.
But most important, is it somewhere enclosed in the NFPA 13.
Thank for your time.
Patrick

If it's a dry system, make sure the couplings have flush seal gaskets, and use the appropriate c factor to account for increased friction inside the pipe.
