Couple of thoughts: 24 is mostly augmentation to the typical underground installation standards applicable when the UG is private fire service main. 24 does not apply to public installation but can.
We get hung up on listings because we use them all the time. Other trades don't. Isn't pipe and fittings traditionally used in sprinkler work exempt from requiring a listing per 13? Galvanized pipe can be directly buried. Ductile can be directly buried. Grooved couplings and fittings are ductile. Gas pipe has to be black steel which cannot be directly buried so buried gas line has to be coated to X mils (I forget exactly) and the joints and fittings also. Presumably black ductile threaded fittings on gas line would not need coating. On Thu, Mar 25, 2010 at 2:22 PM, Thom McMahon <[email protected]> wrote: > Good luck with that!
