Advancing the science and practice of mechanical engineering is the responsibility of the Society's 37 Technical Divisions and Subdivisions, which span a vast array of disciplines, technologies and industries:
The ASME committees within the different divisions and subdivisions develops, updates and publish some of the worlds most used codes and standards. Some of the popular titles are:
ASME 2004 Boiler & Pressure Vessel Code - The Code, which is issued once every three years, is comprised of 28 separate volumes which establish rules of safety governing the design, fabrication and inspection of boilers and pressure vessels, including nuclear power systems. The Code has been updated to incorporate advancements in boiler and pressure vessel design, materials and applications, and provides the latest information to maintain ASME Code Symbol Stamps.
ASME A17-CD - CD-ROM for Elevators and Escalators. Includes: A17.1 Safety Code for Elevators and Escalators - A17.2 Guide for Inspection of Elevators, Escalators and Moving Walks - A17.3 Safety Code for Existing Elevators and Escalators
ASME B31.1 - 2001 Power Piping - The 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. 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; and high temperature water is generated at pressures exceeding 160 PSIG and/or temperatures exceeding 250 degrees F.
ASME B31.3 - 2002 Process Piping - The Code contains rules for piping typically found in petroleum refineries; chemical, pharmaceutical, textile, paper, semiconductor, and cryogenic plants; and related processing plants and terminals. The Code prescribes requirements for materials and components, design, fabrication, assembly, erection, examination, inspection, and testing of piping. The 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. Also included is piping which interconnects pieces or stages within a packaged equipment assembly.
ASME V14.5M - 1994 Dimensioning and Tolerance - The standard establishes uniform practices for stating and interpreting dimensioning, tolerances, and related requirements for use on engineering drawings and in related documents. For a mathematical explanation of many of the principles in this standard, see ASME Y14.5.1m. Practices unique to architectural and civil engineering, land, welding symbology are not included.
ASME B16.5 - 1996 Pipe Flanges and Flange Fittings - The Standard covers pressure-temperature ratings, materials, dimensions, tolerances, marking, testing, and methods of designating openings for pipe flanges and flanged fittings in sizes NPS 1/2 through NPS 24 and in rating Classes 150, 300, 400, 600, 900, 1500, and 2500. Flanges and flanged fittings may be cast, forged, or (for blind flanges and certain reducing flanges only) plate materials as listed in Table 1A. Requirements and recommendations regarding bolting and gaskets are also included.
ASME B31.4 - 1998 - Pipeline Transportation Systems for Liquid Hydrocarbons and other Liquids - The 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. 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, 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. 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 loop; (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 which 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.
