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. ASME B31 was earlier known as ANSI B31. A survey of one of the most important pressure pipe codes - ASME B31, earlier known as ANSI B31RE: High pressure piping backout requirements pipewelder1999 (Industrial) 18 Apr 04 22:44 The purpose for the bottoming clearance in a socket weld is usually to reduce the residual stress at the root of he weld that could occur during solidification of the weld metal. B31.1 - 2012 - Power PipingPiping for industrial plants and marine applications. 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. 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pressures exceeding 160 PSIG and/or temperatures exceeding 250 degrees F. B31.2 - 1968 - Fuel Gas PipingThis has been withdrawn as a National Standard and replaced by ANSI/NFPA Z223.1, but B31.2 is still available from ASME and is a good reference for the design of gas piping systems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).

Users are advised that other piping Code Sections may provide requirements for refrigeration piping in their respective jurisdictions. This Code shall not apply to:
but does include all connecting refrigerant and secondary coolant piping starting at the first joint adjacent to such apparatus. B31.8 - 2012 - Gas Transmission and Distribution Piping SystemsThis Code covers the design, fabrication, installation, inspection, and testing of pipeline facilities used for the transportation of gas. This Code also covers safety aspects of the operation and maintenance of those facilities. B31.8S - 2012 - Managing System Integrity of Gas PipelinesThis Standard applies to on-shore pipeline systems constructed with ferrous materials and that transport gas. Pipeline system means all parts of physical facilities through which gas is transported, including pipe, valves, appurtenances attached to pipe, compressor units, metering stations, regulator stations, delivery stations, holders and fabricated assemblies. The principles and processes embodied in integrity management are applicable to all pipeline systems. This Standard is specifically designed to provide the operator (as defined in section 13) with the information necessary to develop and implement an effective integrity management program utilizing proven industry practices and processes. The processes and approaches within this Standard are applicable to the entire pipeline system. B31.9 - 2011 - Building Services PipingThis Code Section has rules for the piping in industrial, institutional, commercial and public buildings, and multi-unit residences, which does not require the range of sizes, pressures, and temperatures covered in B31.1. This Code prescribes requirements for the design, materials, fabrication, installation, inspection, examination and testing of piping systems for building services. It includes piping systems in the building or within the property limits. B31.11 - 2002 - Slurry Transportation Piping SystemsDesign, construction, inspection, security requirements of slurry piping systems. Covers piping systems that transport aqueous slurries of no hazardous materials, such as coal, mineral ores and other solids between a slurry processing plant and the receiving plant. B31.12 - 2011 - Hydrogen Piping and PipelinesGaseous and liquid hydrogen service and to pipelines in gaseous hydrogen service.
