Users are advised that other piping Code Sections may provide requirements for refrigeration piping in their respective jurisdictions.
This Code prescribes requirements for the materials, design, fabrication, assembly, erection, test, and inspection of refrigerant, heat transfer components, and secondary coolant piping for temperatures as low as -320 deg F (-196 deg C), whether erected on the premises or factory assembled, except as specifically excluded in the following paragraphs. (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.ī31.5 - 2013 - Refrigeration Piping and Heat Transfer Components.(C) Liquid petroleum and liquid anhydrous ammonia piping located on property which has been set aside for such piping within petroleum refinery, natural gasoline, gas processing, ammonia, and bulk plants.(B) Storage and working tanks including pipe-type storage fabricated from pipe and fittings, and piping interconnecting these facilities.(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 loop.Also included within the scope of this Code are: Requirements for offshore pipelines are found in Chapter IX. It does not include support structures such as frames of buildings, buildings stanchions or foundations
It also includes hangers and supports, and other equipment items necessary to prevent overstressing the pressure containing parts. Piping consists of pipe, flanges, bolting, gaskets, valves, relief devices, fittings and the pressure containing parts of other piping components. This Code prescribes requirements for the design, materials, construction, assembly, inspection, and testing of piping transporting liquids such as crude oil, condensate, natural gasoline, natural gas liquids, liquefied petroleum gas, carbon dioxide, liquid alcohol, liquid anhydrous ammonia and liquid petroleum products between producers' lease facilities, tank farms, natural gas processing plants, refineries, stations, ammonia plants, terminals (marine, rail and truck) and other delivery and receiving points. B31.4 - 2012 - Pipeline Transportation Systems for Liquid Hydrocarbons and Other Liquids Also included is piping which interconnects pieces or stages within a packaged equipment assembly. This Code applies to piping for all fluids including: (1) raw, intermediate, and finished chemicals (2) petroleum products (3) gas, steam, air and water (4) fluidized solids (5) refrigerants and (6) cryogenic fluids. This Code prescribes requirements for materials and components, design, fabrication, assembly, erection, examination, inspection, and testing of piping. This Code contains rules for piping typically found in petroleum refineries chemical, pharmaceutical, textile, paper, semiconductor, and cryogenic plants and related processing plants and terminals. B31.3 - 2012 - Process Pipingĭesign of chemical and petroleum plants and refineries processing chemicals and hydrocarbons, water and steam. This has been withdrawn as a National Standard and replaced by ANSI/NFPA Z223.1, but B31.2 is still available from ASME and is a good reference for the design of gas piping systems (from the meter to the appliance). The code covers boiler external piping for power boilers and high temperature, high pressure water boilers in which steam or vapor is generated at a pressure of more than 15 psig (100 kPa gage) and high temperature water is generated at pressures exceeding 160 psig (1103 kPa gage) and/or temperatures exceeding 250 oF (120 oC). This code prescribes minimum requirements for the design, materials, fabrication, erection, test, and inspection of power and auxiliary service piping systems for electric generation stations, industrial institutional plants, central and district heating plants. Piping for industrial plants and marine applications. B31 Code for pressure piping, developed by American Society of Mechanical Engineers - ASME, covers Power Piping, Fuel Gas Piping, Process Piping, Pipeline Transportation Systems for Liquid Hydrocarbons and Other Liquids, Refrigeration Piping and Heat Transfer Components and Building Services Piping.
