AWWA C303-24 Concrete Pressure Pipe, Bar-Wrapped Steel-Cylinder Type

This standard describes the manufacture of concrete pressure pipe, reinforced with a steel cylinder that is helically wrapped with mild steel-bar reinforcement, in sizes ranging from 10 through 72 in. (250 through 1,830 mm), inclusive, and for working pressures up to 400 psi (2,760 kPa). Larger pipe sizes and pipe accommodating higher pressures have been manufactured based on the concepts of this standard. With agreement by the purchaser and the manufacturer, pipe may be manufactured to larger sizes and for higher pressures than indicated herein. This standard does not include requirements for design, handling, delivering, laying, field testing, or disinfecting of pipe and fittings. See AWWA Manual M9, Concrete Pressure Pipe, for that information, as well as certain supplementary design considerations related to thrust restraint, subaqueous installations, and installation in corrosive environments.
It can be referenced in documents for purchasing and receiving concrete pressure pipe, bar-wrapped steel-cylinder type. This standard can be used as a guide for manufacturing concrete pressure pipe with a steel cylinder that is helically wrapped with bar reinforcement. The stipulations of this standard only apply when this document has been referenced in relation to bar-wrapped steel-cylinder concrete pressure pipe.
