Quality Control Test for Prestressing Wires in Concrete Pressure Pipeby Richard O. Lewis,
Abstract: Prestressed concrete cylinder pipe (PCCP) was introduced in 1942 as a high pressure capacity conduit for water transmission. The principal element of the design and construction that imparts high-pressure capacity to the concrete pipe is the high-strength prestressing wire. The FIP - type test, as adapted, is recommended as an annual qualification test for wire manufacturers, to preclude wire with high HE sensitivity from being used in manufacture of prestressed concrete cylinder pipe.
