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: A1119/A1119M − 23 A1119/A1119M − 23a
Standard Specification for
Welded Partially Corrugated Stainless Steel Tube for
Potable Water and General Service
This standard is issued under the fixed designation A1119/A1119M; 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.
1. Scope*
1.1 This specification describes welded austenitic, ferritic, and duplex stainless steel tube on which the external and internal
surface has been modified by a cold forming process to produce an intermittent corrugation for improved formability and resistance
to seismic and other environmental distortions. The tubes are used for potable water service lines and other liquid delivery systems
in nominal diameters from ⁄2 to 2 in. [13 to 50 mm].
1.2 The tube sizes and thicknesses usually furnished to this specification are 0.625 to 2.125 in. [15.88 to 48.60 mm], outside
diameter and 0.028 to 0.049 in. [0.8 to 1.2 mm], inclusive, in wall thickness.
1.3 The grades of austenitic, ferritic, and duplex stainless steels included in this specification shall conform to materials listed in
the governing straight tube Specifications A268/A268M, A269/A269M, or A789/A789M. Selection will depend upon design and
service requirements.
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. 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.
1.5 This specification is expressed in both inch-pound and SI units. However, unless the order specifies the applicable “M”
specification designation (SI units), the material shall be furnished in inch-pound units.
1.6 The following safety hazards statement pertains only to the test methods of this specification. 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.
1.7 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.
