AbstractVarying lengths of ductile iron (DI) pipes were exhumed by several North American water utilities. The exhumed pipes were cut into short sections, sandblasted and tagged. Pipe sections were scanned for external corrosion using a specially developed laser scanner. Scanned corrosion data were processed using specially developed software to obtain information on corrosion depth, area and volume along the pipe. A general definition of corrosion pit was proposed and statistical analyses were subsequently performed on these three geometrical attributes of the pit populations.
