Propane Gas Line Under Concrete Slab

Low hanging lines make it difficult for drivers to navigate.

Propane gas line under concrete slab.

I d really like to come up with the gas line inside the barn in the wall ideally so that the black steel pipe will be hidden thru a concrete slab that will soon be poured. I m traveling but presume he thinks the required tracer tape will be fished along with the propane line. Look for overhead power lines upon installation. Under slab gas line.

The propane line is for a fire pit. Gas line in sewer. I know there could be a leak under the slab but there is only around two pounds of pressure in the gas line it seems unlikely gas would force it s way out if it was surrounded by compacted soil or in concrete. Drain and sewer cleaning.

Code seems to want the pipe to come up on the outside with a riser and seems opposed to entering the building in the wall or even thru a liner of some kind because of. Because gas is heavier than air it wont escape natural gas is lighter than air so it will escape through the vent. His idea is that the propane company will fish the propane line through the conduit. How do i attach a new flange.

Lead 90 flush with concrete slab. I call out gas lines being buried under an exterior slab without properly vented conduit but when people ask how serious a problem this is i have a hard time coming up with an answer. My contractor buried a schedule 40 conduit 18 deep under the gravel bed underlying what will be a flagstone patio. Propane is heavier than air which is why you can never install a propane line under any slab under any conditions.
