When I worked in the oilfield, casing was used to make barbecues. O rings
from flanges were used to build boilers, and there were thousands throughout
southern Louisiana and Texas that were paid for by the oil companies. Don't
know how much those rings cost, but everyone had at least one. Simple
piping with a cap on the end with a small hole drilled, then a countersink
to vee it out. Then just a little wind protection collar that mixed the
outcoming gas with air. A twist variable $20 regulator to the tank. Nice
boilers.

A piece of 20" casing about six feet long made for a heavy barbecue, that
could be properly used as a barbecue with the fire at one end, and the meat
at the other. I had one I made, and helped load many a pup of 20" casing on
a truck or into a trunk.

Damn, I wonder what it would cost for a Sch 40 6' piece of that pipe in
today's dollars. And that didn't include the legs, expanded metal, or any
of the fancy side tables, or 3/8" end plates. Heavy when completed.
