ABSTRACT

During the mid 1990’s this technology entered the pipeline industry for the retrofit of Prestressed ConcreteCylinder Pipe (PCCP)with brokenwires. Back in the early days somewater transmission lineswere built using PCCP. These cylinder pipes consisted of concrete pipes that were manufactured using prestressing wires that imparted compression on the concrete and resisted the internalwater pressures.We arewell aware of the potential for corrosion when using reinforced concrete. Some interesting statistics regarding the use of PCCP:

1. Almost 30 million meters of PCCP was manufactured between 1940 and 2006.
