1.1 This specification covers nominal-wall-thickness tubes intended for use as steam surface condenser tubes. These tubes are made from the austenitic steels listed in Table 1 using a high-frequency induction welding process where post-weld solution heat treatment is not necessary for corrosion resistance.
1.2 The tubing sizes and thickness usually furnished to this specification are 5/8 in. (15.9 mm) to 3 1/8 in. (79.4 mm) in outside diameter and 0.015 to 0.109 in. (0.40 to 2.8 mm), inclusive, in wall thickness. Tubing having other dimensions may be furnished, provided such tubes comply with all other requirements of this specification.
1.3 Optional supplementary requirements are provided in this specification and, when one or more of these are desired, each shall be so stated in the order.
1.4 The values stated in inch-pound units are to be regarded as the standard.
