Summary
ASME does not take any position with respect to the validity of any patent rights asserted in
connection with any items mentioned in this document, and does not undertake to insure anyone
utilizing a standard against liability for infringement of any applicable letters patent, nor assume any
such liability. 122 Design Requirements Pertaining to Specific Piping Systems ... Requirements for
Fabricating and Attaching Pipe Supports ... This Code is more conservative than some other piping
codes, reflecting the need for long service life and maximum reliability in power plant installations.
The Power Piping Code as currently written does not differentiate among the design, fabrication, and
erection re- quirements for critical and noncritical piping systems, except for certain stress
calculations and mandatory nondes- tructive tests of welds for heavy wall, high temperature
applications. Unless agreement is specifically made between contracting parties to use another
issue, or the regulatory body having jurisdiction imposes the use of another issue, the latest edition
issued at least 6 months prior to the original contract date for the first phase of activity covering a
piping system or systems shall be the governing document for all design, materials, fabrication,
erection, examination, and testing for the piping until the completion of the work and initial operation.
component: as used in this Code, is defined as consisting of but not limited to items such as pipe,
piping subassem- blies, parts, valves, strainers, relief devices, fittings, pipe supports, and hangers.
(d) Accelerated creep damage, leading to excessive creep strains and potential pipe rupture, caused
by extended operation above the design temperature shall be considered in selecting the design
temperature for piping to be operated above 800°F (425°C). Piping components, such as pipe, for
which allowable stresses have been developed in accordance with para. The calculated minimum
thickness of piping (or tubing) that is to be threaded shall be increased by an allowance equal to
thread depth; dimension h of ASME B1.20.1 or equivalent shall apply.
