Standard Specification for “Fiberglass” (Glass-Fiber-Reinforced Thermosetting-Resin) Pressure Pipe
This specification covers machine-made fiberglass (glass-fiber-reinforced thermosetting-resin or glass-fiber-reinforced polymer mortar) pressure pipe intended for use in water conveyance systems. It is suited primarily for pipes to be installed in buried applications, although it may be used to the extent applicable for other installations such as, but not limited to, jacking, tunnel lining, and slip lining rehabilitation of existing pipelines. The materials shall include the following: structural wall composition which shall consist of thermosetting resin, glass fiber reinforcement, and, if used, aggregate filler; a thermosetting polyester or epoxy resin with or without filler; E-type glass reinforcement; siliceous sand aggregates; liner and surface layers; unrestrained or restrained joints; and elastomeric gaskets. Pipe shall be supplied in the nominal diameters, lengths, wall thickness, squareness of pipe ends, and soundness. Test specimen shall be subjected to longitudinal loads or circumferential bending to test for its long-term hydrostatic design pressure. The pipe shall conform to the stiffness, hoop-tensile strength, joint tightness, beam strength, longitudinal compressive strength, and longitudinal tensile strength requirements.
1.1 This specification covers machine-made fiberglass pipe, 8 in. (200 mm) through 156 in. (4000 mm), intended for use in water conveyance systems which operate at internal gage pressures of 450 psi (3103 kPa) or less. Both glass-fiber-reinforced thermosetting-resin pipe (RTRP) and glass-fiber-reinforced polymer mortar pipe (RPMP) are fiberglass pipes. The standard is suited primarily for pipes to be installed in buried applications, although it may be used to the extent applicable for other installations such as, but not limited to, jacking, tunnel lining and slip-lining rehabilitation of existing pipelines.
Note 1: For the purposes of this standard, polymer does not include natural polymers.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.
Note 2: There is no known ISO equivalent to this standard.
1.3 The following safety hazards caveat pertains only to the test methods portion, Section 8, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
