Does this propane supply line need to have a conduit or something surrounding it? There is some type of conduit surrounding it as it comes out of the ground but as it goes up the side of the home there is no conduit.

Thanks,

Ryan

Never seen any protection for installations as in the photos up here in Ontario.

NFPA 58 does not require protection except where it could be damaged by a vehicle.

However, if you see grounds where it is reasonable to assume it would get physical impact damage, you can still suggest additional protection. What this does need is an approved shutoff immediately upstream of that regulator. Also, there cannot be any openings in the building 3 ft of either side all the way to the ground or sources of ignition in a 5ft radius.

The pipe downstream of this regulator comes under your applicable gas code: IRC or NFPA 54.
HTH,
Bob

Ryan,
NFPA 58 section 6.8.3 covers underground piping. We sleeve copper tubing underground when we cant get 12" of cover or when vehicle traffic is involved bury it 18" or sleeve it. Copper has been installed unprotected for years however sec 6.8.3.14 states underground metallic piping shall be protected against corrosion as warranted by soil conditions. Section 6.14 covers corrosion protection for all metallic equipment that is mounded or buried. All underground LP tanks should have cathodic protection and / or sacrificial anodes to protect them. Some LP companies regularly test underground tanks to ensure that the tanks are protected.Coated copper or plastic tubing for gas systems is becoming the norm in the Northeast. Hope that helps
