My kids want to try making an in-ground fire pit in our back yard. The pit would be about 3 feet across and surrounded by patio pavers. The right place for it happens to be at the top next to a small hill downward where it would be easy to install a pipe underground out to the side of the hill to drain the pit and provide a vent for the flames. What type of pipe would you bury to act as a vent and drain for a fire pit? Plastic would melt from the heat, but most metal pipes corrode.
