1.1 This specification2 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 Units-The 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.
