This Conley Double Containment Schedule 30/30 Standard Piping Specification covers the requirements for Double Containment machine made reinforced thermosetting resin pipe and fittings, from 1″ – 30″, manufactured according to ASTM D2996, the standard specification for filament wound pipe. These specifications shall cover Schedule 30 Carrier and Schedule 30 Containment pressure process piping, and drain, waste and vent pipe and fittings for use with a broad base of corrosive chemical environments including acids, caustics, various waste solutions, brines and a wide range of solvents. The Epoxy system meets the requirements for FDA.
Both pipe and fittings (tees, elbows, laterals, reducers, and crosses) shall be manufactured with a minimum double Nexus® (synthetic veil) reinforced Epoxy internal corrosion barrier, an Epoxy filament wound fiberglass reinforced cage, and a standard Nexus® reinforced external corrosion barrier. Pipe and fittings have a 25 year guarantee against ultraviolet (UV) degradation (fiber blooming). Conley D.C. (Double Containment) Piping systems are available in a wide range of size, grade and resin combinations, starting with 1 inch carrier pipe. Containment size selection must consider the detection system to be used. See the Conley Product Data for pressure/temperature ratings and span dimensions of each schedule.
Raw materials will meet or exceed specifications for Epoxy resin systems and fiberglass materials. 2.2 The resin, reinforcement, pigments, fillers and other materials, when combined as a composite structure shall produce a pipe that shall meet or exceed the requirements of the classification system listed in ASTM D2310.
