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-fiber reinforced polymer-mortar pipe (RPMP) are fiberglass
pipes. Epoxy-resin and polyester-resin systems are described, and
commercial-grade glass-fiber is specified as the 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.
