This standard describes the manufacture of circumferentially prestressed
concrete pressure pipe with a steel cylinder and wire reinforcement in sizes 16 in.
(410 mm) through 144 in. (3,660 mm). Larger sizes have been manufactured based
on the concepts presented in this standard. The standard describes two types of
prestressed pipe: (1) lined-cylinder pipe with a core composed ora steel cylinder lined
with concrete and subsequently wire-wrapped and coated with premixed mortar, and
(2) embedded-cylinder pipe with a core composed of a steel cylinder encased in
concrete and subsequently wire wrapped and coated with premixed cement mortar.
The design of prestressed concrete pipe is not presented in this standard but is the
subject of ANSI/AWWA C304, Design of Prestressed Concrete Cylinder Pipe. ANSI/
AWWA C301 also does not include requirements for handling, delivering, laying,
field testing, or disinfecting of pipe. See AWWA Manual M9, Cbncrete Pressure Pipe,
for this information.
1.1.1 Essentialrequirements. The pipe shall have the following principal
features: a welded steel cylinder with steel joint rings welded to its ends; for lined-cylinder pipe, a core consisting of a lining of concrete within the steel cylinder, or for
embedded-cylinder pipe, a core consisting of the steel cylinder encased in concrete;
reinforcement consisting of high-tensile wire wound around the outside of the core
in one or more layers at a predetermined stress and fastened securely at its ends; a
coating of dense mortar covering the core and wire, except for the necessarily exposed
surfaces of the joint rings; and a self-centering joint with a preformed gasket of
rubber, designed so that the joint will be watertight under all conditions of service.
Lined-cylinder pipe shall be used for pipe sizes up to and including 20 in. (510 mm)
and may be used for pipe sizes up to and including 60 in. (1,520 mm). Embedded-
cylinder pipe may be used for pipe sizes 24 in. (610 mm) through 60 in. (! ,520 mm)
and shall be used for larger pipe. For embedded-cylinder pipe, at least one third of
the total core thickness shall be outside the cylinder.
