ASME B31.4-2016 pdf free download.Pipeline Transportation Systems for Liquids and Slurries ASME Code for Pressure Piping, B31.
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, ammonia plants, terminals (marine, rail, and truck), and other delivery and receiving points, as well as pipelines transporting 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 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 LX. Requirements for carbon dioxide pipelines are found in Chapter X. Requirements for slurry pipe. lines are found in Chapter Xl.
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 refiner) natural gasoline, gas processing, ammonia, and hulk plants
(d) those aspects of operation and maintenance of liquid pipeline systems relating to the safety and protection of the general public, operating company personnel, environment, property, and the piping systems [see paras. 400(c) and (d)J
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(b)
(C) piping with a design temperature below —20°F (—30°C) or above 250°F (120°C) Ifor applications below
—20°F (—30°C), see paras. 423.2.1(a) and 423.2.61
(d) casing, tubing, or pipe used in oil wells and well- head assemblies
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).
arc welding (AW)’: a group of welding processes that produces coalescence of workpieccs by heating them with an arc. The processes are used with or without the application of pressure and with or without filler metal.
automatic welding’: welding with equipment that requires only occasional or no observation of the welding, and no manual adustmcnt of the equipment controls.
bickfihl: material placed in a hole or trench to fill excavated 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.
