(Specification)Standard Specification for Welded Nickel and Nickel-Cobalt Alloy Tube
Standard Specification for Welded Nickel and Nickel-Cobalt Alloy Tube
ABSTRACT
This specification covers welded tubes made from nickel and nickel-cobalt alloys with UNS Nos. N10001, N10242, N10665, N12160, N10629, N10624, N10675, N10276, N06455, N06007, N06975, N08320, N06985, N06002, N06022, N06030, N06035, N06058, N06059, N06200, N06210, N08031, R30556, N06230, N06686, and R20033. These alloys are intended for heat exchanger and condenser tubes and tubes for general corrosive service for heat-resisting applications. The tubes shall be made from flat-rolled alloy by an automatic welding process with no addition of filler metal, and shall be furnished in the solution annealed and descaled conditions. Materials shall adhere to mechanical (tensile strength, yield strength, and elongation), chemical composition, flattening test, flange test, hydrostatic test, pneumatic test, and eddy current test requirements.
SCOPE
1.1 This specification covers welded tubes made from the nickel and nickel-cobalt alloys (UNS N10001, UNS N10242, UNS N10665, UNS N12160, UNS N10629, UNS N10624, UNS N10675, UNS N10276, UNS N06455, UNS N06007, UNS N06975, UNS N08320, UNS N06985, UNS N06002, UNS N06022, UNS N06030, UNS N06035, UNS N06058, UNS N06059, UNS N06200, UNS N06617, UNS N10362, UNS N06210, UNS N08031, UNS R30556, UNS N06230, UNS N06686, and UNS R20033)2 listed in Table 1 intended for heat exchanger and condenser tubes and tubes for general corrosive service for heat-resisting applications.
1.2 This specification covers tube 1/8 to 31/2 in. (3.2 to 88.9 mm) in outside diameter and 0.015 to 0.148 in. (0.41 to 3.7 mm) inclusive, in wall thickness.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 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.
