An Update on RFEC/TC Technology and Use

摘要

Non-destructive evaluation of the Prestressed Concrete Cylinder Pipelines (PCCP)rnenables the selective repair or replacement of distressed sections, and can alleviate thernprohibitive cost of complete replacement. The RFEC/TC inspection technology isrncapable of detecting prestressing wire failures in PCCP and is currently being used tornidentify and assess distressed pipe sections. An update on the technology and its use isrnpresented including field experiences from recent projects.
