    1. Scope

    1.1 This specification describes the production of welded copper and copper alloy tubes with a longitudinal seam free of filler metal produced from sheet or strip up to 1.5 in. (38.1 mm), in diameter for use in surface condensers, evaporators, heat exchangers, and general engineering applications. The following coppers or copper alloys are involved:

    Copper UNS Nos.

    1.1.1 The (1) external tube surface, (2) internal tube surface, or (3) both internal and external tube surfaces of these tubes shall have a textured surface for improved heat transfer or fluid flow, or both. The strip material used to produce the textured surface tubes have been modified to form a textured surface strip material from a smooth surface strip material by a cold-forming process or series of processes. The produced welded textured tubes may be used in condensers, evaporators, heat exchangers, and other similar heat transfer apparatus in diameters up to and including 1.5 in. (38.1 mm) for various wall thicknesses up to and including 0.07 in. (1.78 mm).

    1.2 The tubing sizes and thicknesses usually furnished to this specification are 1/8 in. (3.2 mm) in inside diameter to 1.5 in. (38.1 mm) in outside diameter and 0.015 in. to 0.070 in. (0.4 mm to 1.78 mm), inclusive, in wall thickness. Tubing having other dimensions may be furnished provided such tubes comply with all other requirements of this specification.

    1.3 Mechanical property requirements do not apply to tubing smaller than 1/8 in. (3.2 mm) in inside diameter or for a wall thickness smaller than 0.015 in. (0.4 mm).

    1.4 Optional supplementary requirements are provided and, when one or more of these are desired, each shall be so stated in the order.

    1.5 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.

    1.5.1 Exception—Values given in inch-pound units are the standard except for grain size, which is stated in SI units.

    1.6 The following safety hazards caveat pertains to the test method 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.7 Mercury has been designated by many regulatory agencies as a hazardous substance that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Use caution when handling mercury and mercury-containing products. See the applicable product Safety Data Sheet (SDS) for additional information. The potential exists that selling mercury or mercury-containing products, or both, is prohibited by local or national law. Users must determine legality of sales in their location.

    1.8 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.
