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 in. through 72 in. (250 mm 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.<\/p>\n

| 7<\/td>\n | Foreword I.\tIntroduction. I.A. Background.\u2003Bar-wrapped steel-cylinder concrete pressure pipe has been manufactured and used extensively for many years. The basic element of the pipe is a welded steel cylinder with steel joint rings welded to the ends, formed and tested in the same I.B.\tHistory.\u2003The first edition of this standard, designated ANSI\/AWWA C303-70, Reinforced Concrete Water Pipe\u2014Steel Cylinder Type, Pretensioned, was approved by the AWWA Board of Directors Jan. 26, 1970.
