Standard Specification for Welded UNS N08120, UNS N08800, UNS N08810, and UNS N08811 Alloy Tubes
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers welded UNS N08120, UNS N08800, UNS N08810 and UNS N08811 alloy boiler, heat exchanger, and condenser tubes for general corrosion resisting and low or high-temperature service. Tube shall be made from flat-rolled alloy by an automatic welding process with no addition or filler metal, shall be cold-worked subsequent to welding and prior to final annealing, and shall be furnished with oxide removed. When bright annealing is used, descaling is not necessary. The material shall conform to the chemical composition limits prescribed for nickel, chromium, iron, manganese, carbon, copper, silicon, sulfur, aluminum, titanium, columbium, molybdenum, phosphorus, tungsten, cobalt, nitrogen, and boron, as determined by chemical analysis, and to the specified mechanical properties including tensile strength, yield strength, and elongation. Annealed alloys shall conform to the the prescribed grain size. The following tests shall be performed: (1) flattening test, (2) flange test, (3) Class 1 nondestructive test by one of the following: hydrostatic, pneumatic (air underwater), eddy current, or ultrasonic test, and (4) Class 2 nondestructive test by leak and electric (eddy current, or ultrasonic test) test.
Scope
1.1 This specification covers welded UNS N08120, UNS N08800, UNS N08810 and UNS N08811* 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 B 751
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 heal practices, and determine the applicability of regulatory limitations prior to use.
