2018-07-26 PCCP is the only piping material that is designed for the combination of internal pressure and external loads. Corrosion Protection - PCCP provides built-in corrosion protection. Due to its unique design combining a steel cylinder lined with concrete and coated with a cement-rich mortar, PCCP is chemically protected from corrosion, passivating all steel elements. Prestressed Concrete Cylinder Pipe (PCCP) is a complex composite structure. For the pipe to function properly, all elements of the structure have to perform as intended. Sonic/ultrasonic testing can be used to evaluate these elements in PCCP. PCCP is manufactured in accordance with the AWWA C301 Standard and is designed in accordance with the AWWA C304 standard.

Distress to PCCP can include broken wires, cracked core, or corroded steel cylinder. Renewal of distressed PCCP may be accomplished by lining the pipe with carbon fiber-reinforced polymer (CFRP), which eliminates the need for excavation and properly construct Portland Cement Concrete Pavement (PCCP). Emphasis will be on acquiring the skills and knowledge that a PCCP Field Supervisor will need to supervise and ensure construction of quality pavements in conformance with the plans and specifications.

The total thickness is about 3.5” greater than the typical 66” PCCP. Uses of PCCP Worldwide . The uses of PCCP pipes are varied. Among all the different concrete pressure pipe dimensions, 1.6-meter diameter PCCPs are used as part of a larger system that transports seawater to be used as cooling agents, and processes water in hot areas.
