scope:
This standard describes the fabrication and the testing of
nominal 1-in. through 156-in. (25-mm through 4,000-mm) fiberglass
pipe and joining systems for use in both aboveground and
belowground water systems. Service and distribution piping systems
and transmission piping systems are included.
Both glass-fiber-reinforced thermosetting-resin pipe (RTRP) and
glass-fiberreinforced polymer mortar pipe (RPMP) are fiberglass
pipes. Epoxy-resin and polyester-resin systems are described, and
commercial-grade E-type glass is specified as the glass-fiber
reinforcement material in the pipe wall. Liner materials
incorporated include thermosetting or thermoplastic resin,
reinforced or unreinforced, with or without fillers. Pressure
classes described are 50, 100, 150, 200, 250, 300, 350, 400, and
450 psig (345, 689, 1,034, 1,379, 1,724, 2,069, 2,414, 2,759, and
3,103 kPa). Stiffness classes described are 9, 18, 36, and 72 psi
(62, 124, 248, and 496 kPa). This standard may be used to the
extent applicable for other diameters, pressure classes, and
stiffness classes. For information on design, hydraulics, and
installation, refer to AWWA Manual M45, Fiberglass Pipe
Design.
Purpose
The purpose of this standard is to provide the minimum
requirements for fiberglass pressure pipe, including design,
fabrication, and testing requirements.
