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. C300 pipe is manufactured using a welded steel cylinder welded to steel joint rings and mild steel reinforcing cage(s). The steel cylinder and cage assembly is encased in cement rich concrete using a vertical cast process. The concrete encasement creates a passivating alkaline environment that protects the steel components from corrosion for the life of the product.
