The program scope includes replacement of all cast-iron main, bare steel, oxyacetylene-welded, threaded, and coupled and cathodically unprotected steel main," said Holly Bowers, executive director of Geospatial and Gas Management Assets for the utility.
SCC is initiated under mechanical stresses and corrosion environment in construction elements of the pipeline at cathodically protected pipe surface, so it is difficult to predict.
When the ICCP system is up and running, the reference electrodes will provide data to show that this is the case, demonstrating that corrosion cannot be initiated and the steel will remain cathodically protected.
