 N B31.4

Annotation

This Code prescribes requirements for the design, materials, construction, assembly, inspection, testing, operation, and maintenance of piping transporting liquids between production facilities, tank farms, natural gas processing plants, refineries, pump stations, ammonia plants, terminals (marine, rail, and truck), and other delivery and receiving points. (See Figs. 400.1.1-1 and 400.1.1-2.)

This Code also prescribes requirements for the design, materials, construction, assembly inspection, testing, operation, and maintenance of piping transporting aqueous slurries of nonhazardous materials such as coal, mineral ores, concentrates, and other solid materials, between a slurry processing plant or terminal and a receiving plant or terminal.

Piping consists of pipe, flanges, bolting, gaskets, valves, relief devices, fittings, and the pressurecontaining parts of other piping components. It also includes hangers and supports, and other equipment items necessary to prevent overstressing the pressurecontaining parts. It does not include support structures such as frames of buildings, stanchions, or foundations, or any equipment such as defined in para. 400.1.2(b).

Requirements for offshore pipelines are found in Chapter IX. Requirements for slurry pipelines are found in Chapter XI.

Also included within the scope of this Code are

(a) primary and associated auxiliary liquid petroleum and liquid anhydrous ammonia piping at pipeline terminals (marine, rail, and truck), tank farms, pump stations, pressure reducing stations, and metering stations, including scraper traps, strainers, and prover loops

(b) storage and working tanks, including pipe-type storage fabricated from pipe and fittings, and piping interconnecting these facilities
