These water tubes made from UNS C10200, C12000, and C12200 copper alloys are commonly used with solder, flared, or compression-type fittings. The materials should be cold-drawn to size and the tubes finished by cold working and annealing to produce the required temper and surface finish. When tubes are furnished in coils, annealing is done after coiling, while those furnished in straight lengths should be in the drawn temper. The numerical values in this specification are not presented in inch-pound units, but rather, in metric or SI units only.1.1 This specification covers seamless copper water tube suitable for general plumbing, similar applications for the conveyance of fluids, and commonly used with solder, flared, or compression-type fittings. The type of copper water tube suitable for any particular application is determined by the internal or external fluid pressure, by the installation and service conditions, and by local requirements. Means of joining or bending are also factors that affect the selection of the type of tube to be used.2NOTE 1: Annealed tube is suitable for use with flared or compression fittings, and with solder-type fittings, provided rounding and sizing of the tube ends is performed where needed.NOTE 2: Drawn temper tube is suitable for use with solder-type fittings. Types A and B tube, in the drawn temper, are suitable for use with certain types and sizes of compression fittings.1.2 The tube shall be produced from the following coppers, and the manufacturer has the option to supply any one of them, unless otherwise specified:CopperUNS No. Previously UsedDesignation Description     C10200 OF Oxygen free without  residual deoxidantsC12000 DLP Phosphorus deoxidized, low residual phosphorusC12200 DHP Phosphorus deoxidized, high residual phosphorus1.3 The assembly of copper plumbing or fire sprinkler systems by soldering is described in Practice B828.1.4 Solders for joining copper potable water or fire sprinkler systems are covered by Specification B32.

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 coldforming process to produce an integral enhanced surface for improved heat transfer. The tubes are typically used in surface condensers, evaporators, and heat exchangers. The seamless copper and copper alloy tubing shall have the internal or external surface, or both, modified by a cold forming process to produce an integral enhanced surface for improved heat transfer. The tube, after enhancing, shall be supplied in the annealed (O61) or as-fabricated temper. The enhanced sections of tubes in the as-fabricated temper are in the cold-worked condition produced by the fabricating operation. The unenhanced sections of tubes in the asfabricated temper are in the temper of the tube prior to enhancing, annealed (O61), or light drawn (H55), and suitable for rolling-in operations. Samples of annealed-temper (O61) tubes selected for test shall be subjected to microscopical examination and shall show uniform and complete recrystallation. Grain size and mechanical properties such as tensile strength and yield strength of the alloys shall be determined. Expansion and flattening tests shall be done to the alloys for performance evaluation. Non-destructive tests such as eddy-current test, hydrostatic test, and pneumatic test shall be done as well.1.1 This specification2 covers 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 The tubes are typically used in surface condensers, evaporators, and heat exchangers.1.3 The product shall be produced of the following coppers or copper alloys, as specified in the ordering information.Copper orCopper AlloyUNS No. Type of Metal   C10100 Oxygen-free electronicC10200 Oxygen-free without residual deoxidantsC10300 Oxygen-free, extra low phosphorusC10800 Oxygen-free, low phosphorusC12000 DLP Phosphorized, low residual phosphorus(See Note 1)C12200 DHP, Phosphorized, high residual phosphorus(See Note 1)C14200 DPA Phosphorized arsenical (See Note 1)C15630 Nickel PhosphorusC19200 Phosphorized, 1 % ironC23000 Red BrassC44300 Admiralty Metal Types B,C44400 C, andC44550 DC60800 Aluminum BronzeC68700 Aluminum Brass Type BC70400 95-5 Copper-NickelC70600 90-10 Copper-NickelC70620 90-10 Copper-Nickel (Modified for Welding)Copper orCopper AlloyUNS No. Type of Metal   C71000 80-20 Copper-Nickel Type AC71500 70-30 Copper-NickelC71520 70-30 Copper-Nickel (Modified for Welding)C72200 Copper-NickelNOTE 1: Designations listed in Classification B224.1.4 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.1.5 Product produced in accordance with the Supplementary Requirements section for military applications shall be produced only to the inch-pound system of this specification.1.6 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Some specific hazards statements are given in Sections 1, 12 and 18.1.7 (Warning—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.
