This specification covers welded nickel-chromium-molybdenum-tungsten alloy (UNS N06110) tube in the annealed condition (temper) for general corrosion applications. The tube shall be made from flat-rolled alloy by an automatic welding process with no addition of filler material. Subsequent to welding and prior to final annealing, the material shall be cold-worked in either the weld metal only or both weld and base metal. The tube shall be furnished with oxide removed. When bright annealing is used, descaling is not necessary. Flattening, flange, and nondestructive tests shall be performed on the tube.

1.1 This specification covers welded UNS N06110 tube in the annealed condition (temper) for general corrosion applications.

1.2 This specification covers outside diameter and nominal wall tube.

1.2.1 The tube sizes covered by this specification are ¹/₈ to 5 in. (3.2 to 127 mm) in outside diameter and 0.015 to 0.148 in. (0.4 to 3.8 mm), inclusive, in wall thickness.

1.3 The values stated in inch-pound units are to be regarded as the standard. The SI units in parentheses are provided for information only.

1.4 The following precautionary caveat pertains only to the test method portion, Section 13, 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 become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.
