Conley Schedule 90M-JF Epoxy Standard Piping Specification

Conley Schedule 90M-JF Epoxy Standard Piping Specification

1.1 This Conley Schedule 90M-JF 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 and offshore piping systems. These specifications shall cover Schedule 90M-JF Jet-Fire Endurance Rated extra heavy duty pressure and process pipe and fittings, firewater deluge and seawater piping for use with a broad base of marine applications. Both Pipe and Fittings (Tees, Elbows, 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, a standard Nexus® reinforced external corrosion barrier, and an external epoxy intumescent fire proof coating. Schedule 90M-JF Piping is tested by Southwest Research Institute in accordance with the Offshore Technology Report OTI 95 634, “Jet-Fire Resistance Test of Passive Fire Protection Materials,” 1996. See the Conley Marine Piping Catalog for a complete listing of all Type Approvals. Pipe and fittings have a 25 year guarantee against ultraviolet (UV) degradation (fiber blooming). 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.
