Standard Specification for Electric-Fusion-Welded Steel Pipe for Atmospheric and Lower Temperatures
|Publication Date:||1 March 2020|
|ICS Code (Iron and steel pipes):||23.040.10|
This specification2 covers electric-fusion-weld
The specification nominally covers pipe 16 in. [400 mm] in outside diameter or larger and of 1⁄4 in. [6 mm] wall thickness or greater. Pipe having other dimensions may be furnished provided it complies with all other requirements of this specification.
Several grades and classes of pipe are provided.
Grade designates the type of plate used as listed in 5.1.
Class designates the type of heat treatment performed during manufacture of the pipe, whether the weld is radiographically examined, and whether the pipe has been pressure tested as listed in 1.3.3.
NOTE 1-Selection of materials should be made with attention to temperature of service. For such guidance, Specification A20/A20M may be consulted.
The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. The inch-pound units shall apply unless the "M" designation of this specification is specified in the order.
This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
