ABSTRACT:
This disclosure teaches protecting from lightning damage a reinforced concrete pipe line. The pipe line generally comprises a plurality of pipe lengths each having a bell at one end and a spigot at the other end thereof. The bell of one pipe length receives the spigot of a next pipe length fitted therein. Each of the pipe lengths is provided with at least one longitudinal metallic reinforcing wire or rod having a bell end and a spigot end. The pipe line carries lightning electrical current along a relatively long portion thereof by means of an electrical lead joining the bell end of the reinforcing wire or rod of one pipe length to the spigot end of the reinforcing wire or rod of the next pipe length. By this expedient lightning electrical energy is dissipated into the earth through the relatively long portion of the pipe line.
