1.1This 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 ¹/₂to 2 in. [13 to 50 mm].

1.2The 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.

1.3The 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.

1.4The 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.

1.5This 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.

1.6The 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.

1.7This 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.
