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...



My first choice would be polyethelene pipe that is rated for gas. You can
bury black pipe that is coated too, but it is more work and may not last as
long. The poly pipe would need to be done by someone that does HVAC work for
a living as it usually is not available to the general public. You probably
could dig the trench and have them lay the pipe.
Another concern would be the size of pipe. At 200 ft you may need to have
the gas utility bump your gas pressure up to 2 PSI to get the capacity you
will need.
