Organization: ASTM International
Publication Date: 1 October 2007
Status: inactive
Page Count: 9
ICS Code (Boilers and heat exchangers): 27.060.30
scope:

1.1 This specification establishes the requirements for heat exchanger tubes manufactured from forge-welded copper and copper alloy tubing in straight lengths on which the external or internal surface, or both, has been modified by cold forming process to produce an integral enhanced surface for improved heat transfer.

1.2 Units-The values stated in either inch-pounds 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
C12000

A

DLP Phosphorized, low residual phosphorus
C12200

A

DHP Phosphorized, high residual phosphorus
C19200Phosphorized, 1 % iron
C23000Red Brass
C44300Admiralty, arsenical
C44400Admiralty, antimonial
C44500Admiralty, phosphorized
C68700Aluminum Brass
C7040095-5 Copper-Nickel
C7060090-10 Copper-Nickel
C7062090-10 Copper-Nickel (Modified for Welding)
C7100080-20 Copper-Nickel
C7150070-30 Copper-Nickel
C7152070-30 Copper-Nickel (Modified for Welding)
C72200Copper-Nickel

A Copper UNS Nos. C12000, and C12200 are classified in Classification B 224.

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. ^REFERENCE:
