Prestressed concrete pressure pipe (CPP) is in widespread use throughout Canadaand the United States, with a total of some 19,000 mi (30,000 km) of pipe in usein North America's major water utilities. Many of these lines are more than 50years old, and half are expected to need repair or replacement over the next 20years. To selectively maintain these lines and avoid costs from catastrophic pipefailures, utilities needed an inspection technique that was highly sensitive,reliable, effective, and economical. An innovative electromagnetic technique,based on the remote field eddy current (RFEC) inspection technique, has beendeveloped that allows nonintrusive inspection of prestressed CPP. Full-scaletesting conducted on embedded cylinder pipes and bar-wrapped pipelinesdemonstrated the new RFEC technique's sensitivity to both single and multiplebreaks in prestressing wire.
