Prestressed concrete cylinder pipe (PCCP) consists of a concrete core, a thin steel cylinder, high tensile prestressing wires, and a mortar coating. Concretes high compressive strength and steels high tensile strength forms a durable structure that can stand extreme condition. The thick mortar coating on the pipe protects the steel cylinder, joint rings, and pre-stressing wire from corrosion, which makes it ideal for water transmission, municipal wastewater applications, and industrial piping. PCCP does not require any bracing, compacted bedding, trucking in aggregate, unshrinkable fill, and welding, which makes it easier and economical to install.
