1.1 This specification established the requirements for welded tube of copper and various copper alloys up to 31/8in., inclusive, in diameter, for use in surface condensers, evaporators, heat exchangers, and general engineering applications. The following coppers or copper alloys are involved:
|Copper or |
Copper Alloy UNS No.2
|Type of Metal|
|C10800A||...||oxygen-free, low phosphorus|
|C12200A||...|| DHP phosphorized, high|
|C68700||...||arsenical aluminum brass|
|C70620||...||90-10 copper-nickel (Modified|
|C71520||...||70–30 copper-nickel (Modified|
A Copper UNS Nos. C10800 and C12200 are classified in Classification B224.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the 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 establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
