Standard Specification for Glass Fiber Reinforced Polyethylene (PE-GF) Spiral Wound Large Diameter Pipe
2020

ASTM Vol.08.04 (2023)
This specification covers requirements and test methods for materials, dimensions, workmanship, joining systems, and marking for large diameter, 12 in. [300 mm] and larger, inside diameter controlled glass fiber reinforced polyethylene (PE-GF) spiral wound pipe with electrofusion joints. The piping is intended for new construction and renewal of existing piping systems used for the transport of water, slurries, municipal sewage, domestic sewage, effluents, etc., in pressure systems. NOTE 1: Pipe produced to this specification should be installed in accordance with Practice D2774 or F1668, where applicable, and with the manufacturer’s recommendations. The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text the SI units are shown in brackets. The values stated in each system may not be exact equivalents: therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. All pipes produced under this specification are pressure-rated. This specification includes criteria for choice of raw material and test methods for evaluation of raw material, together with performance requirements and test methods for determining conformance with the requirements. In referee decisions, the SI units shall be used for metric-sized pipe and inch-pound units for pipe sized per ANSI (ANSI B 36.10).
