(Specification)Standard Specification for Welded Copper Heat Exchanger Tubes With Internal Enhancement
Standard Specification for Welded Copper Heat Exchanger Tubes With Internal Enhancement
ABSTRACT
This specification establishes the requirements for welded, internally enhanced copper tube, in straight lengths or coils, suitable for use in refrigeration and air conditioning products or other heat exchangers. The following types of welded tubes are: as-welded and welded tube, subsequently annealed. The material of manufacture shall be sheet or strip, of the required alloy, and may be either cold worked or annealed. The welded tube shall be manufactured from either cold rolled or annealed sheet or strip. The sheet or strip shall be formed into a tubular shape on a suitable forming mill. The material shall conform to the chemical requirements specified. The microstructure shall show complete recrystallization and shall have an average grain size within the limits specified. Nondestructive examination, electromagnetic test, cleanness requirements, and cuprous oxide requirement shall be made to conform to the specified requirements.
SCOPE
1.1 This specification establishes the requirements for welded, internally enhanced copper tube, in straight lengths or coils, suitable for use in refrigeration and air conditioning products or other heat exchangers.
1.2 Units—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.
1.3 The product shall be produced of the following coppers. Unless otherwise specified, tubes made from any one of these coppers may be supplied:
Copper UNS No.
Type of Metal
C10200
Oxygen-free without residual deoxidants
C12200
Phosphorized, high residual phosphorus (DHP)
1.4 The following pertains to the test method described in 18.5 of 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, health, and environmental practices and determine the applicability of regulatory requirements prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
