ASTM A530 Standard Specification

ASTM A530 / A530M – 12 Standard Specification for General Requirements for Specialized Carbon and Alloy Steel Pipe


ASTM A106 Gr.B Seamless pipe Marking

ASTM A530 Standard covers a general requirements for specialized carbon and alloy steel pipe. Tensile tests, tension tests, flattening tests, hydrostatic tests and ultrasonic tests shall be made to conform to the requirements specified. If the mechanical results do not conform to the requirements specified, retests shall be made. Defects in seamless pipe shall be repaired by welding.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.


1.1 This specification covers a group of requirements which, with the exceptions of Section 6.3, Section 14, Section 21, and Section 22, are mandatory requirements to the ASTM pipe product specifications noted below unless the product specification specifies different requirements, in which case the requirement of the product specification shall prevail.

1.2 Sections 6.3 or 21 are mandatory if the product specification has a requirement for product analysis or flattening tests.

1.3 Section 22 is mandatory if the product specification has a hydrostatic test requirement without defining the test parameters.

1.4 Section 14 is for information only.

1.5 In case of conflict between a requirement of the product specification and a requirement of this general requirement specification, only the requirement of the product specification need be satisfied.

Title of Specification ASTM DesignationA
Seamless Carbon Steel Pipe for High-Temperature
Metal-Arc-Welded Steel Pipe for Use With High-Pressure Transmission Systems A381
Seamless Carbon Steel Pipe for Atmospheric and
Lower Temperatures
Centrifugally Cast Carbon Steel Pipe for High-Temperature Service A660
Electric-Fusion-Welded Steel Pipe for Atmospheric and Lower Temperatures A671/A671M
Electric-Fusion-Welded Steel Pipe for High-Pressure Service at Moderate Temperatures A672/A672M
Carbon and Alloy Steel Pipe, Electric-Fusion-Welded for High-Pressure Service at High Temperatures A691/A691M

A These designations refer to the latest issue of the respective specifications.

1.6 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 are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. The inch-pound units shall apply unless the “M” designation (SI) of the product specification is specified in the order.

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.”

1.7 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 and health practices and determine the applicability of regulatory limitations prior to use.
