This specification covers nickel-iron-chromium alloys in the form of welded, cold-worked, and annealed pipe for general corrosive service and heat resisting applications. These products are furnished three alloys: UNS N08120, UNS N0880, and UNS N08810. The materials shall conform to the required chemical composition for nickel, chromium, iorn, manganese, carbon, copper, silicon, sulfur, aluminum, titanium, columbium, molybdenum, phosphorus, tungsten, cobalt, and nitrogen. The materials shall conform to the requred mechaniical properties such as tensile strength, yield strength, and elongation. A transverse sample representing the full wall thickness of annealed alloys UNS N08120 and N08810 shall conform to the average grain size. Pipe shall be capable of withstanding, without cracking, flattening under a load applied gradually. Each piece of each lot shall be subjected to hydrostatic test, pneumatic test, eddy current test, ultrasonic test, leak test, electric test, and transverse guided bend test.

1.1 This specification2 covers nickel-iron-chromium alloys in the form of welded, cold-worked, and annealed pipe for general corrosive service and heat-resisting applications. These products are furnished in three alloys: UNS N08120, UNS N08800, and UNS N08810.3 Alloy UNS N08800 is employed normally in service temperatures up to and including 1100 °F (593 °C). Alloys UNS N08120 and UNS N08810 are employed normally in service temperatures above 1100 °F where resistance to creep and rupture is required, and are annealed to develop controlled grain size for optimum properties in this temperature range. 1.2 This specification covers outside diameter and nominal wall pipe shown in ANSI B36.19. Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of the specification. 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 establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 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. |
