The pipeline industry has many road and railroad crossings with casings which have been in service for more than 50 years without exhibiting any major problems, regardless of whether the casing is shorted to or isolated from the carrier pipe. The use of smart pigging and continual visual inspection when retrieving a cased pipeline segment have shown that whether shorted or isolated, casings have no significant bearing on the presence or absence of corrosion on the carrier pipe.
