ASTM A524/A524M-21

Standard Specification for Seamless Carbon Steel Pipe for Atmospheric and Lower Temperatures

ABSTRACT
This specification covers seamless carbon steel pipe intended primarily service at atmospheric and lower temperatures. The steel shall be killed steel made by one or more of the following processes: open-hearth, electric-furnace, or basic-oxygen. The steel shall be made to fine grain practice and may be cast in ingots or may be strand cast. All hot-finished and cold-drawn pipe shall be heat treated and be cooled in air or in the cooling chamber of a controlled atmosphere furnace. The steel shall be subjected to flattening, hydrostatic, bend, and tensile tests. A retest shall be conducted if a specimen breaks in an inside or outside surface flaw.
SCOPE
1.1 This specification2 covers seamless carbon steel pipe intended primarily for service at atmospheric and lower temperatures, NPS 1/8 to 26 [DN 6 to 650] inclusive, with nominal (average) wall thickness as given in ANSI B36.10. Pipe having other dimensions may be furnished, provided such pipe complies with all other requirements of this specification. Pipe ordered to this specification shall be suitable both for welding, and for bending, flanging, and similar forming operations.  
1.2 The product is available in two grades (Tables 1 and 2).  
1.3 Product may be either of hot finished or cold drawn manufacture (see 5.1.4 and 5.1.5).  
1.4 Units—This specification is expressed in both inch-pound units and in SI units; however, unless the purchase order or contract specifies the applicable M specification designation (SI units), the inch-pound units shall apply. The values stated in either inch-pound units or SI 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 nonconformance with the standard. The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
Note 1: The dimensionless designator NPS (nominal pipe size) has been substituted in this standard for such traditional terms as “nominal diameter,” “size,” and “nominal size.”  
1.5 The following hazard caveat applies to the test methods portion, Section 16, only.  This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
