Standard Specification for Seamless Nickel and Nickel-Cobalt Alloy Pipe and Tube

ABSTRACT
This specification covers seamless pipe and tube of nickel and nickel-cobalt alloys. These alloys are classified into different grades according to chemical composition. Mechanical properties of the material like tensile strength, yield strength, and elongation shall be measured. Tension, hydrostatic, and nondestructive electric tests shall be done on each pipe or tube. The mass or weight of each pipe shall be calculated and the chemical composition of each pipe shall be determined.
SCOPE
1.1 This specification2 covers seamless pipe and tube of nickel and nickel-cobalt alloys. covers seamless pipe and tube of nickel and nickel-cobalt alloys.    
1.2 Alloys that can currently be certified to this specification are (UNS N10001, UNS N10242, UNS N10665, UNS N12160, UNS N10675, UNS N10276, UNS N06455, UNS N06007, UNS N08320, UNS N06975, UNS N06002, UNS N06985, UNS N06022, UNS N06035, UNS N06044, UNS N08135, UNS N06255, UNS N06058, UNS N06059, UNS N06200, UNS N10362, UNS N06030, UNS N08031, UNS N08034, UNS R30556, UNS N08535, UNS N06250, UNS N06060, UNS N06230, UNS N06235, UNS N06686, UNS N10629, UNS N06210, UNS N10624, and UNS R20033)3.  
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 Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, 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.
