1-1 SCOPE
(a) This Standard provides requirements for the design, materials, manufacture, fabrication, installation, examination,andtestingofglass-fiber-reinforcedthermo- setting-resin (FRP) piping systems.
(b) FRP piping, as used in this Standard, includes pipe, flanges, bolting, gaskets, valves, fittings, special connect- ingcomponents,andthepressure-containingorpressure- 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 over- stressing the pressure-containing components.
1-1.1 Content and Coverage
(a) This Standard addresses pipe and piping compo- nents 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 manu- factured 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 ofthis 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.
1-1.2 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
1-2 TERMS AND DEFINITIONS
Commonly used terms relating to FRP piping aredefined below.Some terms are defined with specific refer-ence to piping.The definitions generally agree with thosein ASME BPVC,Section X; ASME RTP-1; ASTM D883; andASTM F412.Definitions taken unchanged from other stan-dards are indicated by a footnote.
adhesive: a material designed to join together two othercomponent materials by surface attachment (bonding).adhesive joint: a bonded joint made using an adhesive onthe surfaces to be joined.
binder’: in a reinforced plastic, the continuous phase thatholds together the reinforcement.
bloom’.a visible exudation or efflorescence on the surfaceof a material.
bonder2: one who performs a manual or semiautomaticbonding operation.
bonding procedure : the detailed methods and practicesinvolved in the production of a bonded joint.Bonding Procedure Specification (BPS): a documentproviding in detail the required variables and proceduresfor the bonding process to ensure repeatability in thebonding procedure.
butt-and-wrapped joint: a bonded joint made by applyingplies of reinforcement saturated with resin to the surfacesto be joined.
