ASTM A524-96
(Specification)Standard Specification for Seamless Carbon Steel Pipe for Atmospheric and Lower Temperatures
Standard Specification for Seamless Carbon Steel Pipe for Atmospheric and Lower Temperatures
SCOPE
1.1 This specification covers seamless carbon steel pipe intended primarily for service at atmospheric and lower temperatures, NPS 1/8 to 26 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 values stated in inch-pound units are to be regarded as the 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".
1.3 The following hazard caveat applies to the test methods portion, Section 16, only. This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
