BC Environmental and Occupational Health Research Network

The objective of this project is to provide an evaluation of technologies and development plan that can be applied to non-interruptive, non-destructive condition assessment of small diameter (less than 16 inch or approximately 400 mm) cast iron and ductile iron pipe (CIP and DIP). The focus will be on technologies which can estimate the amount of remaining structural metal in the pipe wall compared to the amount of non-structural material (i.e. graphitized material, slag inclusions, casting porosities or other manufacturing defects, corrosion pits, etc.), or as close to that as possible, for both unlined and cement mortar-lined CIP and DIP of small diameter.
