·  ASME B31.1 Power Piping-This Code prescribes requirements for the design, materials, fabrication, erection, test, and inspection of power and auxiliary service piping systems for electrical generation stations, industrial and institutional plants, central and district heating plants, and district heating systems, except as limited by para. 100.1.3. These systems are not limited by plant or property lines unless they are specifically limited by para. 100.1. Piping as used in this Code includes pipe, flanges, bolting,gaskets, valves, relief devices, fittings, and the pressure containing portions of other piping components. It also includes hangers and supports and other equipment items necessary to prevent overstressing the pressure containing components. The users of this Code are advised that in some areas legislation may establish governmental jurisdiction over the subject matter covered in this Code. However, any such legal requirement shall not relieve the owner of his inspection responsibilities specified in para. 136.1.

·  ASME B31.2 Fuel Gas Piping-Material, This Code covers the design, fabrication, installation, and testing of piping systems for fuel gases such as natural gas, manufactured gas, liquified petroleum gas-air mixtures above the upper combustible limit, liquified petroleum gas in the gaseous phase, or a mixture of these gases. Included within the scope of this Code are fuel gas piping systems both in buildings and between buildings, form the outlet of the consumer's meter set assembly (or point of delivery) to and including the first pressure containing valve upstream of the gas utilization device. Piping systems within the scope of this Code include all components such as pipe, valves, fittings, flanges (except inlet and outlet flanges that are a part of equipment or apparatus described in para. 200.1.4), bolting and gaskets. Also included are the pressure containing parts of other components such as expansion joints, strainer and metering devices, and piping supporting fixtures and structural attachments.

·  ASME B31.3 Process Piping- Rules for the Process Piping Code have been developed considering piping typically found in chemical, petroleum refineries, pharmaceutical, textile, paper, semiconducter, and cryogenic plants; and related processing plants and terminals. This Code prescribes requirements for materials and components, design, fabrication, erection, assembly, examination, inspection, and testing of piping. this Code applies to all fluids, including: raw, intermediate, and finished chemicals; petroleum products; gas, steam, air, and water; fluidized solids; refrigerants;and cryogenic fluids.
