Pipeline Transportation Systems for Liquids and Slurries
Published by ASME International, 12/08/2022
ASME B31.4, 2022 Edition – Pipeline Transportation Systems for Liquids and Slurries
ASME B31.4 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.
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 here 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.
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 protection of the general public, operating company personnel, environment, property, and the piping systems
Key Changes to this revision include:
- Revise allowable expansion stress within B31.4 to better align with other B31 code books
- Add references to API 1133
- Addition of “water” to Chapter XI
- Clarification on the distinction between gray and ductile cast irons
- Clarification and consistency of etchant composition in paragraphs 4188.8.131.52 and 434.8.7
- Nonmandatory Appendix B revised and updated to reflect the latest editions of numerous referenced standards
