(Specification)Standard Specification for Aluminum and Aluminum-Alloy Drawn Seamless Tubes for Surface Condensers, Evaporators, and Heat Exchangers (Metric)
Standard Specification for Aluminum and Aluminum-Alloy Drawn Seamless Tubes for Surface Condensers, Evaporators, and Heat Exchangers (Metric)
ABSTRACT
This specification covers drawn seamless aluminum-alloy tube of specified tensile properties for use in surface condensers, evaporators, and heat exchangers. The tube shall be produced by drawing an extruded tube made from hollow extrusion ingot (cast in hollow form or pierced) and extruded by use of the die and mandrel method. The tube shall be subjected to tension, leak, and expansion tests.
SCOPE
1.1 This specification covers aluminum-alloy (Note 1) drawn seamless round tube in straight lengths designated as shown in the Table 2, for use in surface condensers, evaporators, and heat exchangers.
Note 1: Throughout this specification use of the term alloy in the general sense includes aluminum as well as aluminum alloy.
Note 2: For drawn seamless tubes used in general applications, see Specifications B210 and B210M; for extruded tubes see Specifications B221 and B221M; for seamless pipe and seamless extruded tube used in pressure applications, see Specification B241/B241M; and for structural pipe and tube see Specification B429/B429M. (A) Limits are in percent maximum unless shown as a range or otherwise stated.(B) Analysis shall be made for the elements for which limits are shown in this table.(C) For purposes of determining conformance to these limits, an observed value or a calculated value attained from analysis shall be rounded to the nearest unit in the last right-hand place of figures used in expressing the specified limit, in accordance with the rounding-off method of Practice E29.(D) Others includes listed elements for which no specific limit is shown as well as unlisted metallic elements. The producer may analyze samples for trace elements not specified in this specification. However, such analysis is not required and may not cover all metallic Others elements. Should any analysis by the producer or the purchaser establish that an Others element exceeds the limit of Each or that the aggregate of several Others elements exceeds the limit of Total, the material shall be considered nonconforming.(E) Other Elements—Total shall be the sum of unspecified metallic elements 0.010 % or more, rounded to the second decimal before determining the sum.(F) Vanadium 0.05 max.(G) The aluminum content shall be calculated by subtracting from 100.00 % the sum of all the metallic elements present in amounts of 0.010 % or more, rounded to the second decimal before determining the sum.(H) Composition of cladding alloy as applied during the course of manufacture. The sample from finished tube shall not be required to conform to these limits.(I) In case there is a discrepancy in the values listed in Table 1 with those listed in the “International Alloy Designations and Chemical Composition Limits for Wrought Aluminum and Wrought Aluminum Alloys” (known as the “Teal Sheets”), the composition limits registered with the Aluminum Association and published in the “Teal Sheets” shall be considered the controlling composition. The “Teal Sheets” are available at http://www.aluminum.org/tealsheets. (A) To determine conformance to this specification, each value for tensile strength and for yield strength shall be rounded to the nearest 1 MPa and each value for elongation to the nearest 0.5 %, both in accordance with the rounding-off method of Practice E29.(B) The basis for establishment of mechanical property limits is shown in Annex A1.
1.2 Alloy and temper designations are in accordance with ANSI H35.1M. The equivalent Unified Numbering System alloy designations are those of Table 1 preceded by E215, for example, A91060 for aluminum 1060, in accordance with Practice E527.
1.3 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A1.
1.4 This specification is the SI companion to Specification B234.
1.5 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 th...
