1.1 This Conley Schedule 90C Epoxy Standard Piping Specification covers requirements for machine made reinforced thermosetting resin pipe and fittings, 1″ – 20″, manufactured according to ASTM D 2996 or ASTM F 1173 or IMO A.753(18), the standard specification for filament wound pipe used in marine piping systems. These specifications shall cover Schedule 90C Conductive extra heavy duty pressure and process pipe and fittings for use with a broad base of marine applications in hazardous areas as well as corrosive chemical environments including acids, caustics, various waste solutions, brines and a wide range of solvents. The Epoxy systems meet the requirements for FDA.
Both Pipe and Fittings (Tees, Elbows, Reducers, and Crosses) shall be manufactured with a minimum double Nexus® (synthetic veil) reinforced Conductive Epoxy internal corrosion barrier, an Epoxy filament wound fiberglass reinforced cage with a conductive filament, and a standard Nexus® reinforced external corrosion barrier. Pipe and fittings have a 25 year guarantee against ultraviolet (UV) degradation (fiber blooming). Schedule 90 Series pipe and fittings are ABS Type Approved for shipboard piping without the fire protective coating. Conley Series 90 Piping Systems are also for Low Pressure Fiberglass Line Pipe, FW (Filament Wound), for use in conveying produced fluids including oil and non-potable water in the oil and gas producing industries. 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 D 2310.
