Corrosion in Underground fire mains
Corrosion in Underground fire mains
(OP)
Recently came across high corrosion in an underground fire ring main of MS construction(no coating) that runs on top of a mains electrical cable feeding the site.My understanding is that stray currents caused by a DC field can cause corrosion in pipe lines.Can an AC field cause corrosion in pipe lines?

These should be treated like natural gas lines, OD coatings and cathodic protection.
