ASTM B587-2019 pdf free download.Standard Specification for Welded Brass Tube
1. Scope
1.1 This specification establishes the requirements for round, rectangular, and square copper alloy welded tube for general engineering applications. 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 following safety hazard caveat pertains only to the test method(s) described in this specification: 1.3.1 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 appro- priate safety, health, and environmental practices and to determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Terminology
3.1 For definitions of terms related to copper and copper alloys, refer to Terminology B846. 3.2 Definitions ofTerms Specific to This Standard: 3.2.1 as-welded—a condition created as a result of shaping sheet, strip, or plate into a tubular form and welding without subsequent heat treatment or cold work, or both. 3.2.2 ends—straight pieces, shorter than the nominal length, left over after cutting the product into mill lengths, stock lengths, or specified lengths. They are subject to minimum length and maximum weight requirements. 3.2.3 fully finished—welded tube with internal and pro- cessed to conform to the specified temper. 3.2.4 mill length—lengths that can be conveniently manu- factured in the mills. 3.2.5 mill lengths with ends—lengths, including ends, that can be conveniently manufactured in the mills. 3.2.6 specific—straight lengths that are uniform in length, as specified, and subject to established tolerances. 3.2.7 stock—straight lengths that are mill cut and stored in advance of orders. They are usually subject to established tolerances. 3.2.8 welded and annealed—welded tube that has been annealed to produce a uniformed grain size appropriate to the specified annealed temper.3.2.9 welded and cold-drawn—welded tube with internal flash removed by scarfing and subsequently cold-drawn to conform to the specified temper.
4. Classification (Type)
4.1 The basic types of welded brass tube are: 4.1.1 Type I—As-welded tube finished by passing through sizing and straightening rolls at ambient temperature. 4.1.2 Type II—As-welded tube finished by sizing, straightening, and annealing. 4.1.3 Type III—As-welded tube finished by cold reducing or cold drawing over a plug or mandrel. 4.1.4 Type IV—As-welded tube finished by both cold draw- ing over a plug or mandrel and annealing, and redrawing and annealing when necessary to conform to a specified size and temper. Type IV tube may be substituted for Types I, II, and III by agreement between the manufacturer or supplier and the purchaser. The temper of substituted Type IV tube shall be stated in the contract or purchase order.
6. Material and Manufacture
6.1 Material—The material of manufacture shall be strip, sheet, or plate produced of Copper Alloy UNS No. C21000, C22000, C23000, C26000, C26800, C27000, or C27200 [or other designation] of such purity and soundness as to be suitable for processing into the products described herein. 6.2 Manufacture: 6.2.1 Tubes shall be welded by any process which produces forged or fusion welds. Tube welded from flat rolled strip can be regularly furnished by welding standard strip tempers and shall have mechanical properties as agreed upon between the manufac- turer or supplier and the purchaser. 6.2.2 Forged-welded tube shall be scarfed to remove both internal and external flash. Forged-welded tube to be drawn over a mandrel to produce Types III and IV may have the internal flash com- pletely removed. Forged-welded Types I, II, and III tube may contain a residual thickness at the weld not to exceed 0.006 in. (0.15 mm) or 10 % of the nominal wall thickness, whichever is greater. 6.2.3 Fusion-welded tube shall be mechanically worked to produce a smooth external and internal surface without the application ofscarfing or other removal ofthe weld metal bead.
