Historical (view previous versions of standard)
This specification covers UNS N02200 nickel alloy and UNS N02201 and N04400 low carbon nickel alloy welded pipes intended for general corrosive service and for mechanical applications. Each pipe should either be welded and annealed or welded and stress relieved and made from the flat-rolled alloys by an automatic welding process without any filler metal additions. The pipes should also be cold worked after welding to ensure the development of optimum corrosion resistance in the weld area and base metal during the final heat treatment.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers nickel (UNS N02200) and low carbon nickel (UNS N02201 and UNS N04400) in the form of welded and annealed or welded and stress relieved pipe intended for general corrosive service and for mechanical applications.
1.2 This specification covers outside diameter and nominal wall pipe in Schedules 5S, 10S, and 40S through 30-in. nominal pipe size shown in ANSI B36.19 (see Table 1). Pipe having other dimensions may be furnished provided such pipe 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 The following precautionary caveat pertains only to the test methods portion, Section 12, of this specification: This standard does not purport to address all of the safety problems, 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.
