DESCRIPTION

1.1 This specification describes welded austenitic 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 1/2 to 2 in.

1.2 The tube sizes and thicknesses usually furnished to this specification are 0.625 to 2.125 in. outside diameter and 0.028 to 0.049 in., 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 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.
