Anotácia

This specification covers machine-made glass-fiber-reinforced thermosetting-resin (fiberglass) pipes such as reinforced thermosetting-resin pipe (RTRP) and reinforced polymer mortar pipe (RPMP; natural polymers not included) for use in gravity-flow systems for conveying sanitary sewage, storm water, and some industrial wastes. Material covered is of various type (RPMP/RTRP polyester or epoxy), liners (reinforced or non-reinforced thermoset liner, thermoplastic liner, or none), grades (polyester resin surface layer-reinforced or non-reinforced, polyester resin and sand surface layer-non-reinforced, epoxy resin surface layer-reinforced or non-reinforced, or none), and pipe stiffness. The pipe shall be manufactured as a composite structure consisting of resin, reinforcements, colorants, fillers, and other materials, free from all defects such as indentations, delaminations, bubbles, pinholes, cracks, pits, blisters, foreign inclusions, and resin-starved areas that are detrimental to the strength and serviceability of the pipe. The pipe shall also be uniform in color, opacity, density, and other physical properties, with the inside surface of the pipe free of bulges, dents, ridges, and other defects. The pipes shall be joined together using a joining system that will provide for fluid tightness in conformity with the service requirement and with the pipe joint surfaces free of dents, gouges, and other surface irregularities. Compression, tension, and long-term chemical tests as well as tests for dimensions, stiffness, and joint tightness shall be performed and shall conform to the requirements specified.
