(Specification)Standard Specification for Seamless UNS N08020, UNS N08026, and UNS N08024 Nickel-Alloy Pipe and Tube
Standard Specification for Seamless UNS N08020, UNS N08026, and UNS N08024 Nickel-Alloy Pipe and Tube
ABSTRACT
This specification covers UNS N08020, UNS N08026 and UNS N08024 nickel-alloy seamless, cold-worked or hot-finished pipe and tube intended for general corrosive service. The product of UNS N08020 alloy, UNS N08026 alloy, and UNS N08024 alloy shall be furnished in the stabilized-annealed condition, solution-annealed condition, and annealed condition, respectively. The tensile strength, yield strength, and elongation requirements are specified. Hydrostatic and nondestructive electric tests shall be conducted on the each pipe or tube.
SCOPE
1.1 This specification covers UNS N08020, UNS N08026, and UNS N08024 seamless, cold-worked or hot finished pipe and tube intended for general corrosive service.
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 The following safety hazards caveat pertains only to the test methods portion, Section 10, of this specification: 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.
