400.1.1 This Code prescribes requirements for the design, materials, construction, assembly, inspection, testing, operation, and maintenance of liquid pipeline systems between production fields or facilities, tank farms, above- or belowground storage facilities, natural gas processing plants, refineries, pump stations, ammo- nia plants, terminals (marine, rail, and truck), and other delivery and receiving points, as well as pipelines trans- porting liquids within pump stations, tank farms, and terminals associated with liquid pipeline systems. (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 ofnonhazardous materials such as coal, mineral ores, concentrates, and other solid materials, between a slurry processing plant or terminal and a receiving plant or terminal (see Fig. 400.1.1-3). Piping consists of pipe, flanges, bolting, gaskets, valves, relief devices, fittings, and the pressure- containing parts of other piping components. It also includes hangers and supports, and other equipment items necessary to prevent overstressing the pressure- containing 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 carbon dioxide pipelines are found in Chapter X. Requirements for slurry pipe- lines are found in Chapter XI. Also included within the scope of this Code are (a) primaryand associated auxiliary liquid petroleum and liquidanhydrous ammoniapipingatpipeline termi- nals (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 (c) liquid petroleum and liquid anhydrous ammonia piping located on property that has been set aside for such piping within petroleum refinery, natural gasoline, gas processing, ammonia, and bulk plants (d) those aspects of operation and maintenance of liquid pipeline systems relating to the safety and protec- tionofthe general public, operatingcompanypersonnel, environment, property, and the piping systems [see paras. 400(c) and (d)]
Some of the more common terms relating to piping are defined below. For welding terms used in this Code but not shown here, definitions in accordance with AWS A3.0 apply. accidental loads: any unplanned load or combination of unplanned loads caused by human intervention or natu- ral phenomena. active corrosion: corrosion that is continuing or not arrested. anomaly: an indication, detected by nondestructive examination (such as in-line inspection). arc welding (AW) 1 : a group of welding processes that produces coalescence of workpieces by heating them with an arc. The processes are used with or without the application of pressure and with or without filler metal. automaticwelding 1 : weldingwithequipmentthatrequires only occasional or no observation of the welding, and no manual adjustment of the equipment controls. backfill: material placed in a hole or trench to fill exca- vated space around a pipeline. blunt imperfection: an imperfection characterized by smoothly contoured variations in wall thickness. 2 breakaway coupling: a component installed in the pipeline to allow the pipeline to separate when a predetermined axial load is applied to the coupling.buckle: a condition where the pipeline has undergone sufficient plastic deformation to cause permanent wrin- kling in the pipe wall or excessive cross-sectional defor- mation caused by loads acting alone or in combination with hydrostatic pressure. butt weld (typically, a butt joint, single V-groove weld): a weld between two members aligned approximately in the same plane. cathodic protection (CP): technique to reduce the corrosion of a metal surface by making that surface the cathode of an electrochemical cell. characterize: to quantify the type, size, shape, orientation, and location of an anomaly. coating: liquid, liquefiable, or mastic composition that, after application to a surface, is converted into a solid protective or functional adherent film. Coating also includes tape wrap.
