Electrolytic corrosion of water pipeline system in the remote distance from stray currents—Case study

Case study of corrosion failure of urban water supply system caused by the harmful effects of stray currents was presented. The failure occurred at a site distant from the sources of these currents namely the tramway and railway traction systems. Diagnosis revealed the stray currents flow to pipelin...
