Reinforced Concrete
Cylinder Pipe (AWWA C300)

In nominal diameters from 36″ to 144″ with standard laying lengths of 12′ to 20′ (depending on diameter).

Prior to the early 1940s and the introduction of C301, Reinforced Concrete Cylinder Pipe (RCCP) was the most commonly used Concrete Pressure Pipe in the United States and Canada. RCCP (C300) is manufactured in accordance with the AWWA C300 Standard and is designed in accordance with the AWWA Manual M9.

First manufactured in 1919, RCCP (C300) consists of a watertight welded steel cylinder with steel joint rings at each end, one or two circumferential reinforcing cages of steel wire or bars, and a high-strength concrete structural core. The steel cylinder, joint rings and reinforcing cage assembly is encased in Portland cement concrete using a vertical casting process. In addition to providing significant structural strength, the concrete encasement provides a passivating alkaline environment that protects the embedded steel components from corrosion for the life of the product.

C300 features

  • Designed for Project Requirements – RCCP (C300) 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.
  • Ease of Installation – RCCP is installed in less time on-site due to its rigid conduit design attribute. RCCP needs no special bedding or backfilling under normal ground conditions.
  • Corrosion Protection – RCCP provides built-in corrosion protection due to its unique design, combining the steel components encasement in concrete. The cement-rich concrete encasement chemically protects (passivates) all steel elements from corrosion.
  • High Pressure Capacity – RCCP (C300), designed as a rigid pipe, is manufactured to handle typical municipal transmission pressures and loads. However, higher-pressure capacities are available (in surplus of 2760kPa, or 400psi) if project requirements warrant. Maximum loads and pressures depend on pipe diameter, wall thickness and steel/cage reinforcement.
