Prestressed Concrete Cylinder Pipe Embedded Type (AWWA C301E)

Prestressed Concrete Cylinder Pipe (PCCP; embedded) combines concrete’s high compressive strength to form durable structures that can stand up to any water and/or wastewater project requirements.

PCCP (C301E) is manufactured in accordance with the AWWA C301 standard and is designed in accordance with the AWWA C304 standard. There are many major benefits achieved by using PCCP. The source of all these benefits is the pipe’s unique design concept, featuring steel cylinder encased in a rugged prestressed concrete. The mortar coating on the pipe creates a passivating alkaline environment that protects the steel cylinder, joint rings and pre-stressing wire from corrosion. Since concrete continues to gain strength while underground, the materials in PCCP will be increasingly protected over many decades of service.

Size: In diameters from 1050mm to 3600mm with standard lengths of 4.877m or 6.096m (depending on diameter)

C301E Features:

Ease of Installation & Economical – PCCP is installed in less time on site. Because it is a rigid conduit, PCCP needs no special bedding or backfilling under normal ground conditions. Installing any other pipe material often requires bracing, highly compacted bedding, trucking in aggregate, unshrinkable fill, and/or welding—each adds cost, time and potential problems.
High Pressure Capacity – PCCP has the high strength to withstand internal and external loads. The pipe's concrete and steel wall is prestressed with steel wire to provide more than sufficient strength to withstand the pressure requirements. The rigid wall fully supports the external forces of the surrounding earth. 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.
Designed for Project Requirements – PCCP is custom-designed and made for every application. Each section of pipe, along with each fitting, can be made to meet the pressure loadings and special configuration required.
