This Code prescribes minimum requirements for the design,
materials, fabrication, assembly, erection, examination,
inspection, and testing of piping systems for electric generation
stations; industrial and institutional plants; central and district
heating plants; and district heating systems, both on the property
of and within the buildings of the users.
Piping as used in this Code includes 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.
Rules governing piping for miscellaneous appurtenances, such as
water columns, remote water level indicators, pressure gages, gage
glasses, etc., are included within the scope of this Code, but the
requirements for boiler appurtenances shall be in accordance with
Section I of the ASME Boiler and Pressure Vessel Code, PG-60.
The users of this Code are advised that in some areas
legislation may establish governmental jurisdiction over the
subject matter covered by this Code. However, any such legal
requirement shall not relieve the owner of his inspection
responsibilities specified in Para. 136.1.
