scope:

This standard covers the manufacture of reinforced concrete cylinder pipe that is not prestressed or pretensioned in sizes from 30 in. to 144 in. (750 mm to 3700 mm), inclusive. Larger sizes have been manufactured based on the concepts of this standard. This type of pipe is designed for the internal pressure, external loads, and bedding conditions designated by the purchaser. This standard does not include design procedures for the pipe or requirements for handling, delivering, laying, field testing, or disinfecting the pipe (see current edition of AWWA Manual M9, Concrete Pressure Pipe).

Essential requirements. The pipe shall have the following principal features: a welded steel cylinder with steel joint rings welded to its ends; a reinforcing cage or cages of steel bars, wire, or welded wire fabric surrounding the steel cylinder; a wall of dense concrete covering the steel cylinder and reinforcing cage or cages inside and out; and a joint with a performed gasket of rubber, designed so that the joint will be watertight
