ASTM B704-00

Standard Specification for Welded UNS N06625, UNS N06219 and UNS N08825 Alloy Tubes

SCOPE
1.1 This specification covers welded UNS N06625 and UNS N08825 alloy boiler, heat exchanger, and condenser tubes for general corrosion resisting and low or high-temperature service.
1.2 This specification covers tubes 1/8 to 5 in. (3.18 to 127 mm), inclusive, in outside diameter and 0.015 to 0.500 in. (0.38 to 12.70 mm), inclusive, in wall thickness. Table 2 of Specification B751 lists the dimensional requirements of these sizes. Tubes having other dimensions may be furnished provided such tubing complies with all other requirements of this specification.
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
