ASME B31.4:2012 pdf download.Pipeline Transportation Systems for Liquids and Slurries.
400.1.1 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 (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 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
(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 proteclion of the general public, operating company personnel, environment, property, and the piping systems Isee paras. 400(c) and (d)]
400.1.2 This Code was not developed to apply to
(a) building service piping, such as water, air, or steam
(b) pressure vessels, heat exchangers, pumps, meters, and other such equipment including internal piping and connections for piping except as limited by para. 423.2.4(h)
(c) piping with a design temperature below —20°F (—30°C) or above 250°F (120°C)
(d) casing, tubing, or pipe used in oil wells and well- head assemblies
(12) 400.2 Definitions
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 natural phenomena.
active corrosion: corrosion that is continuing or not arrested.
anomaly: an indication, detected by nondestructive examination (such as in-line inspection).ASME B31.4 pdf download.
