AWWA C950-01 pdf download.FIBERGLASS PRESSURE PIPE
This standard describes the fabrication and the testing of nominal 1-in. through 144-in (25-mm through 3,600 mm) fberglass 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 glas-fiber-reinforeed thermosetting-resin pipe (RTRP) and glass fiber- reinforced polymer mortar pipe (RPMP) are fiberglass pipes. Epoxy-resin and polyester- resin kystems are described, and commercial-grade E-type glas is speeified as the glass-fiber reinforcement. material in the pipe wall. Liner materials incorporated include thermosetting or thermoplastie resin, reinforced or unrein- forced, with or without illers, Pressure classes deseribed are 50, 100, 150, 200, und 250 psig (345, 689, 1,034, 1,379, and 1.724 kPa), Stiffhess dlasses 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 stifiness dlasses. For information on design, hydraulics, and installation, refer to AWWA Manual M45, Fiberglass Pipe Design.
The following definitions shall apply in this standard:
1. Aggregate: Siliceous 6and conforming to ASTM C33, except that the requirements for gradation need not apply,
2. Centrifugal casting; A proces used to manufacture tubular goods by applying resin and reinforcement to the inside of a mold that is rotated and heated, subsequently polymerizing the resin system. The outside diameter (OD) of the finisbed pipe is determined by the inside diameter (ID) of the mold tube. The ID of the finished pipe is determined by the amount of material introduced into the mold. Other materials that will not adversely affiect the laminate performance may be introduced in the process during manufacture of the pipe.
3. Constructor: The party that provides the work and materials for placement. or installation.
4. Epaxy resin (thermosetting!: A polymer containing two or more three -mem- bered rings, each conaisting of one oxygen and two carbon atoms, The polymer is cured by eross-linking with an amine or anhydride hardener, with or without heat, catalyst, or both,
5. Fiberglass pipe: A tubular product containing glass-fiber reinforcements embedded in or surrounded by cured thermoetting resin, The composite strueture may contain aggregate, granular or platelet fllers, thixotropie agents, and pigments or dyes, Thermoplastic or thermosetting liners or coatings may be included.AWWA C950-01 pdf download.
