I'm contemplating running natural gas from the gas entrance to my house to
a
workshop approx. 200' away.

What type pipe can I use when running underground ?? I'm told that there
is
plastic pipe for gas lines ??

I live in south louisiana where it's very humid.

Thanks...


Where I live you could use galvanized, black iron or poly.
Poly is out cause no one other that the utility has the tools and parts to
work with it. It is not allowed for residences other than the service. Which
is utility owned.

galvanized and black iron both need to insulated from the ground. That can
be done by tape or foam, here. You should be checking locally to see what
the rules are.

You should be contacting a plumber that can help you with the calculation to
your new load. Depending on the size of the load you could be running 2
inch or larger pipe.
