scope:

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 information on these topics.

Essential requirements. The pipe shall have the following principal features: a welded steel cylinder with sized steel joint rings welded to the ends; a lining of concrete or cement mortar centrifugally applied within the steel cylinder and spigot ring; reinforcement consisting of continuous steel bar helically wound tightly around the outside of the cylinder and securely fastened by welding to the steel joint ring at each end of the cylinder; a coating of dense mortar covering the cylinder and bars, except for the necessarily exposed surfaces of the spigot joint ring; and a self-centering joint with a preformed gasket of rubber, so designed that the joint will be watertight under all conditions of service.

Purpose

The purpose of this standard is to provide the minimum requirements for concrete pressure pipe, bar-wrapped, steel-cylinder type, including fabrication and testing requirements.

Application

This standard 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 to bar-wrapped, steel-cylinder concrete pressure pipe.
