Gas Piping

[PhoenixBob]

I don't see a section for Fuel Gas for Residential so I take it is to be posted here.

My question is do any of your jurisdictions allow black pipe under slab in a sleeve to an island without any special requirements other than sealing and venting the sleeve to the outside?

PB,

See 2006 IRC, G2415.11 Piping Underground beneath buildings. It's longer than I want to type; but, if you don't have the book; I'll type it. There are special requirements and if the plumbers don't already know them, and have experience with this type installation they have no business making this installation.

Also, when (not if) it aquires a leak; the floor is going to have to be removed to replace the pipe.

Hope this helps,

Uncle Bob

Re: Gas Piping

G2415.11 (404.11) Piping underground beneath buildings.

Piping installed underground beneath buildings is prohibited

except where the piping is encased in a conduit of wrought

iron, plastic pipe, or steel pipe designed to withstand the superimposed

loads. Such conduit shall extend into an occupiable

portion of the building and, at the point where the conduit terminates

in the building, the space between the conduit and the

gas piping shall be sealed to prevent the possible entrance of

any gas leakage. If the end sealing is capable of withstanding

the full pressure of the gas pipe, the conduit shall be designed

for the same pressure as the pipe. Such conduit shall extend not

less than 4 inches (102 mm) outside the building, shall be

vented above grade to the outdoors, and shall be installed so as

prevent the entrance of water and insects. The conduit shall be

protected from corrosion in accordance with Section G2415.8.
