ASTM A192/A192M-17

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.
Designation: A192/A192M − 02 (Reapproved 2012) A192/A192M − 17
Standard Specification for
Seamless Carbon Steel Boiler Tubes for High-Pressure
Service
This standard is issued under the fixed designation A192/A192M; the number immediately following the designation indicates the year
of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.
A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the U.S. Department of Defense.
1. Scope Scope*
1.1 This specification covers minimum-wall-thickness, seamless carbon steel boiler and superheater tubes for high-pressure
service.
1.2 The tubing sizes and thicknesses usually furnished to this specification are ⁄2 in. to 7 in. [12.7 to 177.8 mm] outside diameter
and 0.085 to 1.000 in. [2.2 to 25.4 mm], inclusive, in minimum wall thickness. Tubing having other dimensions may be furnished,
provided such tubes comply with all other requirements of this specification.
1.3 Mechanical property requirements do not apply to tubing smaller than ⁄8 in. [3.2 mm] inside diameter or 0.015 in. [0.4 mm]
thickness.
1.4 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 of this specification is specified in the order.
1.5 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.
