2、r of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers aluminum and aluminum-alloy(Note 1) formed and arc-welded round tube in diameters 9 to
3、60 in. 230 to 1520 mm, made from formed sheet or plate, buttwelded by gas-tungsten or gas-metal arc-welding methods withor without the use of filler metal.NOTE 1Throughout this specification use of the term alloy in thegeneral sense includes aluminum as well as aluminum alloy.NOTE 2The requirements
4、for the sheet and plate used are the same asin Specifications B209 or B209M.1.2 Alloy and temper designations are in accordance withANSI H35.1/H35.1M. The equivalent Unified NumberingSystem alloy designations are those of Table 1 preceded byA9,for example, A91100 for aluminum 1100 in accordance with

Materials and Manufacture5.1 The tube shall be made by roll forming (or other suitableforming) sheet or plate into a circular contour with thelongitudinal edges butted together for welding, or5.2 The sheet or pl
37、ate shall be roll formed so that the edgesare butted together in a helical pattern around the circumfer-ence of the tube.5.3 The edges shall be welded together by a gas-shielded-arc process, qualified in accordance with Section IX of theASME Boiler and Pressure Vessel Code.5.4 Filler metal shall be
38、in accordance with AWS Specifi-cation A 5.10.5.5 Any butt-joint configuration (square, Vee, J, bevel-groove, etc.) may be used on either or both sides (single ordouble groove) at the option of the producer within thecapability or limitations of his welding equipment. Whetherwelded from one side (squ
39、are-butt or single-groove) or bothsides (square-butt or double-groove) the face reinforcementand root reinforcement shall not increase the joint thickness bymore than 50 % of the wall thickness or18 in. 3 mm,whichever is smaller. The reinforcements may be dressed tothis dimension or removed entirely
40、 at the manufacturersoption. The weld shall show complete penetration. Backwelding is permitted only when (or provided that) it is part ofthe original welding process; it must not be employed only asa repair procedure for areas of unsatisfactory penetration. Theweld bead shall show no evidence of un
41、der filling on either theroot or reinforcement side. The toe of the weld shall blendsmoothly into the parent material with no undercutting oroverlapping. If tubing is produced by welding individuallyfabricated sections together, longitudinal butt welds shall bepositioned so as to be at least 45 apar
42、t.6. Quality Assurance6.1 Responsibility for InspectionUnless otherwise speci-fied in the contract or purchase order, the producer or supplieris responsible for the performance of all inspection and testrequirements specified herein. Except as otherwise specified inthe contract or order, the produce
43、r or supplier may use his ownor any other suitable facilities for the performance of theinspection and test requirements specified herein, unless dis-approved by the purchaser. The purchaser shall have the rightto perform any of the inspections and tests set forth in thisspecification where such ins
44、pections are deemed necessary toassure that the material conforms to prescribed requirements.6.2 Lot DefinitionAn inspection lot shall be defined asfollows:6.2.1 For heat-treated tempers, an inspection lot shall con-sist of all material of the same mill form, alloy, temper, andnominal dimensions tra
45、ceable to a heat-treat lot or lots, andsubjected to inspection at one time.6.2.2 For nonheat-treated tempers, an inspection lot shallconsist of all material of the same mill form, alloy, temper, andnominal dimensions subjected to inspection at one time.7. Chemical Composition Requirements7.1 Limits:
46、7.1.1 The tube shall conform to the chemical compositionlimits prescribed in Table 1. Conformance shall be determinedby the manufacturer of the sheet and plate used to produce thetube by analyzing samples taken at the time the ingots arepoured, in accordance with E716 and analyzed in accordancewith
47、E607, E1251, E34 or EN 14242. At least one sample shallbe taken for each group of ingots poured simultaneously fromthe same source of molten metal. If the tube manufacturer usessheet or plate whose chemical composition has been deter-mined by analyzing samples taken at the time the ingots werepoured
48、, they shall not be required to sample and analyze thefinished product.NOTE 4It is standard practice in the United States aluminum industryto determine conformance to the chemical composition limits prior tofurther processing of ingots into wrought products. Due to the continuousnature of the proces
49、s, it is not practical to keep a specific ingot analysisidentified with a specific quantity of finished material.7.1.2 The specific filler metal alloy shall be selected by themanufacturer from Table number A2 of AWS SpecificationA 5.10; however, the filler alloy selected shall ensure conform-ance with the requirement of 10.2.2.7.2 If it becomes necessary to analyze the finished orsemifinished product for conformance to chemical compositionlimits, the method used to sample the finished or semifinishedproduct for the determinatio
