(Specification)Standard Specification for Welded UNS N06625, UNS N06219 and UNS N08825 Alloy Tubes
Standard Specification for Welded UNS N06625, UNS N06219 and UNS N08825 Alloy Tubes
ABSTRACT
This specification covers welded tubes made of UNS N06625, UNS N06219 and UNS N08825 alloys for use in boilers, heat exchangers and condensers for general corrosion prevention in either low or high-temperature environments. This standard contains information on manufacturing, chemical composition, mechanical properties and dimensional requirements for the welded tubes.
SCOPE
1.1 This specification covers welded UNS N06625, UNS N06219 and UNS N08825 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. Specification B751 lists the dimensional requirements of these sizes. Tubes having other dimensions may be furnished provided such tubing complies with all other requirements of this specification.
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 health practices, and determine the applicability of regulatory limitations prior to use.
