Standard Details

Scope:
GENERAL

The ASME B31 Code for Pressure Piping and the ASME Boiler and Pressure Vessel Code, Section III, Nuclear Components, Subsections NC and ND piping rules require the use of stress intensification factors (i-factors or SIFs) when checking the adequacy of components and joints (welded and nonwelded) in piping subject to loadings, including those cyclic loadings that may produce fatigue failures. As used herein, where the word "Code" is used without specific identification, it means the Code or Standard which incorporates or references this Standard. The piping Codes provide stress intensification factors for the most common piping components and joints. This Standard presents an experimental method to determine SIFs.

NASA Lessons:
This lesson addresses a catastrophic failure of a high pressure (225 psig) steam line strainer largely due to inappropriate use of material and the violation of the maximum allowance stress for the cast iron strainer per ASME B31.1. This lesson is relevant to paragraphs 122.3.1, 122.7.4, and 124.6 of this ASME Prssure Piping code

Title : Standard Test Method for Determining Stress Intensification Factors (i-Factors) for Metallic Piping Components

Publication Date: 05/30/2008 - Base Document

Description :

Rules for this Code Section have been developed considering the needs for applications which include piping typically found in electric power generating stations, in industrial and institutional plants, geothermal heating systems, and central and district heating and cooling systems.

This Code prescribes requirements for the design, materials, fabrication, erection, test, inspection, operation, and maintenance of piping systems.

Piping as used in this Code includes pipe, flanges, bolting, gaskets, valves, relief devices, fittings, and the pressure containing portions of other piping components, whether manufactured in accordance with Standards listed in Table 126.1 or specially designed. It also includes hangers and supports and other equipment items necessary to prevent overstressing the pressure containing components.

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.
