scope:

(a) This Standard provides requirements for the design, materials, manufacture, fabrication, installation, examination, and testing of fiber-reinforced thermosetting-resin (FRP) and dual laminate piping systems.

(b) FRP and dual laminate piping, as used in this Standard, includes pipe, flanges, bolting, gaskets, valves, fittings, special connecting components, and the pressure-containing or pressure-retaining portions of other piping components, whether manufactured in accordance with references cited in this Standard or specially designed. It also includes hangers and supports and other items necessary to prevent overstressing the pressure-containing components.

Content and Coverage

(a) This Standard addresses pipe and piping components that are produced as standard products, as well as custom products that are designed for a specific application. It covers FRP pipe and piping components manufactured by contact molding, centrifugal casting, filament winding, and other methods. Its intent is to provide a uniform set of requirements for FRP pipe and piping components that can be adopted by reference in the various piping codes, including sections of the ASME B31 Code for Pressure Piping. This Standard is published as a separate document to reduce duplication between piping codes.

(b) Requirements of this Standard apply to FRP piping systems typically used within the scope of the various sections of the ASME B31 Code for Pressure Piping (ASME B31.1, ASME B31.3, ASME B31.4, ASME B31.5, ASME B31.8, and ASME B31.9) and selected piping systems designed to the ASME Boiler and Pressure Vessel Code (BPVC), Section III, Division 1, Subsection ND.

Exclusions

This Standard does not provide requirements for the following:

(a) metallic pipe

(b) thermoplastics, ceramics, and other nonmetallic materials used to fabricate pipe and piping components

(c) dual laminate construction that combines thermoplastic linings with FRP pipe and fittings

(d) reinforced polymer mortar pipe

(e) products with fiber-reinforcement materials that are not made from glass

(f) nonmetallic pressure vessels, valves, and specialty components covered by other ASME codes and standards, such as ASME BPVC, Section X and ASME RTP-1

(g) piping for which the maximum internal pressure exceeds 1 700 kPa (250 psi)

(h) piping for which the algebraic product of internal pressure [in kilopascals gauge (pounds per square inch gauge)] and internal diameter [in meters (inches)] exceeds 1 262 kPag·m (7,200 psig·in.)

(i) piping used as ductwork conveying air or other gases at pressures within 6.89 kPag (1 psig) of the pressure of the surrounding atmosphere
