If it's black pipe in the ground, the pipe and joints should be wrapped
with plumbers tape or some equivalent covering. You could also add
galvanic protection to it, such as a zinc anode buried and wired to the
pipe above ground. The parts above ground can be painted with a rust
preventing paint.
Asphault coat all underground black pipe. Asphault and wrap better
yet.
