First used in the early 1900s, reinforced concrete non-cylinder pipe (RCNCP) C302 consists of one or two circumferential reinforcing cages of steel wire or bars, steel joint rings with skirts and a high-strength concrete structural core. The steel 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.
RCNCP is suitable for working pressures up to 55 psi. The pipe is manufactured per the AWWA C302 Standard and is designed in accordance with the AWWA Manual M9.
