Introduced in the early 1900s, Reinforced Concrete Non-Cylinder pipe (RCNP) is suitable for working pressures up to 380kPa (55psi).
Reinforced Concrete Non-Cylinder pipe (C302) is manufactured in accordance with the AWWA C302 standard and is designed in accordance with the AWWA Manual M9. C302 pipe is manufactured using one or more reinforcing cages (depending on diameter and depth of bury) and steel joint rings complete with steel skirts. The steel cage(s) 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.
