Standard Specification for UNS N08028 and N08029 Seamless Pipe and Tube
ABSTRACT
This specification covers the standard requirements for UNS N08028 seamless cold-finished or hot-finished pipe and tube intended for general corrosive services. The pipe and tube shall be furnished in the solution-annealed condition and heat treated at a certain range of temperature by subsequent quenching in water or rapidly cooling by other means. Chemical and product analysis shall be conducted on each lot of material as described in a referenced ASTM document and shall conform to the required chemical composition for carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel, molybdenum, copper, and iron. The material shall also be subjected to tension test, flaring test, and hydrostatic or nondestructive test to determine its mechanical properties which shall be in conformity with the tensile strength, yield strength, and elongation requirements.
SCOPE
1.1 This specification covers UNS N08028 and N08029 seamless cold-finished or hot finished pipe and tube intended for general corrosive service. The general requirements are covered in Specification B829.
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 be come 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.
