Standard Specification for Nickel Seamless Pipe and Tube

ABSTRACT
This specification covers the standard requirements for nickel (UNS N02200) and low-carbon nickel (UNS N02201) in the form of cold-worked seamless pipe and tube. The material shall conform to the specified chemical composition limits for nickel, copper, iron, manganese, carbon, silicon, and sulfur which shall be determined by chemical analysis. Tension test shall be performed; wherein, the tensile properties for the material specified as small-diameter and light-wall tube shall be in conformity with the tensile strength, yield strength, and elongation requirements. Each pipe or tube shall also be subjected to nondestructive electric test or hydrostatic test in accordance with a referenced ASTM document to determine the allowable fiber stress for the annealed and stress-relieved materials.
SCOPE
1.1 This specification2 covers nickel (UNS N02200)3 and low-carbon nickel (UNS N02201)3 in the form of cold-worked seamless pipe and tube in the conditions shown in Table 1 and Table X1.1.  
1.1.1 Hot-worked material is available. Properties are to be agreed upon between the manufacturer and purchaser.  
1.2 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.  
1.3 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.  
1.4 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.
