Standard Specification for Copper and Copper-Alloy Seamless Condenser and Heat Exchanger Tubes With Integral Fins
|Publication Date:||10 October 2002|
|ICS Code (Non-ferrous metal pipes):||23.040.15|
1.1 This specification establishes the requirements for seamless copper and copper alloy tubing on which the external or internal surface, or both, has been modified by a cold-forming process to produce an integral enhanced surface for improved heat transfer.
1.2 UnitsThe values stated in either in-pound units or SI units are to be regarded separately as the standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems could result in nonconformance with the specification.
1.3 The tubes are typically used in surface condensers, evaporators, and heat exchangers.
1.4 The product shall be produced of the following coppers or copper alloys, as specified in the ordering information.
|Copper or Copper Alloy UNS No.||Type of Metal|
|C10200||Oxygen-free without residual deoxidants|
|C10300||Oxygen-free, extra low phosphorus|
|C10800||Oxygen-free, low phosphorus|
|C12000||DLP Phosphorized, low residual phosphorus (See Note 1)|
|C12200||DHP, Phosphorized, high residual phosphorus (See NOTE 1)|
|C14200||DPA Phosphorized arsenical (See NOTE 1)|
|C19200||Phosphorized, 1 % iron|
|C44300||Admiralty Metal Types B,|
|C68700||Aluminum Brass Type B|
|C70620||90-10 Copper-Nickel (Modified for Welding)|
|C71000||80-20 Copper-Nickel Type A|
|C71520||70-30 Copper-Nickel (Modified for Welding)|
Note 1-Designations listed in Classification B 224.
1.5 The following safety hazard caveat pertains only to the test methods described in 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 establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
1.6 Product produced in accordance with the Supplementary Requirements section for military applications shall be produced only to the inch-pound system of this specification.
