1、Designation: B744/B744M 05 (Reapproved 2011)Standard Specification forAluminum Alloy Sheet for Corrugated Aluminum Pipe1This standard is issued under the fixed designation B744/B744M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision,
2、 the year 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 alloy sheets used inthe fabrication of corrugated aluminum pipe inten
3、ded for usefor storm water drainage, underdrains, culverts, and similaruses. The material is furnished corrugated in cut lengths, anduncorrugated in coils and cut lengths.1.2 The values stated in either inch-pound units or SI unitsare to be regarded separately as standard. Within the text, theSI uni
4、ts are shown in brackets. The values stated in eachsystem are not exact equivalents; therefore, each system shallbe used independently of the other. Combining values from thetwo systems may result in nonconformance with the standard.1.3 This standard does not purport to address all of thesafety conc
5、erns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Mechanical Requirements6.1 The sheet material shall conform to the requirements formechanical properties specified in Specification
17、 B209B209M, when tested prior to corrugating or other fabrication.NOTE 2Sheet material tested after corrugating and other fabricatingshould conform to the specified tensile and yield strength requirements,but due to cold working, conformance to the elongation requirements maynot be obtained.7. Gener
18、al Requirements7.1 Aluminum alloy sheets or coils supplied under thisspecification shall conform to the applicable requirements ofSpecification B209 B209M (as appropriate) for alclad alloy3004-H34 for riveted pipe or alclad alloy 3004H32 for helicalpipe.8. Dimensions and Tolerances8.1 Sheet thicknes
19、s shall conform to dimensions prescribedin Table 1.8.2 The thickness of cladding shall be as specified inSpecification B209 B209M.8.3 Permissible variations in flat width, length and square-ness shall be in accordance with ANSI H35.2 H35.2M.8.4 Corrugations shall form smooth continuous curves andtan
20、gents. The dimensions of the corrugations shall be inaccordance with Table 2.8.5 Covering width of corrugated sheet shall be in accor-dance with Table 3. Covering width is the distance between thecrests of the extreme corrugations. There is no establishedtolerance for overall width since the coverin
21、g width and lipdimensions are the governing factors for the formed product.The lip dimension of corrugated sheet shall be in accordancewith Table 4. This dimension is measured along the radialcurvature from the crest of the corrugation to the edge of thesheet.9. Sampling and Testing9.1 Sampling and
22、testing shall be according to SpecificationB209 B209M. The manufacturer shall make adequate testsand measurements to ensure that the material produced com-plies with this specification.9.1.1 Test results including chemical composition, mechani-cal properties, and cladding thickness shall be maintain
23、ed bythe sheet manufacturer for seven years and shall be madeavailable to the fabricator and purchaser upon request, forexamination at the manufacturers facility unless otherwiseagreed upon.9.2 The fabricator or the purchaser may make such tests asare necessary to determine the acceptability of the
24、material orto verify the correctness of a certification.9.3 Mechanical properties shall be determined on sheetprior to corrugating or other fabricating, except tests may bemade after fabrication by the purchaser for tensile and yieldstrengths.10. Rejection10.1 Material tested by the purchaser and fo
25、und not con-forming to this specification may be rejected.11. Certification11.1 When specified in the purchase order or contract, amanufacturers certification shall be furnished to the purchaserof the sheet (fabricator) or to the purchaser of the finished pipestating that samples representing each l
26、ot have been tested andinspected in accordance with this specification and the require-ments have been met. When specified in the purchase order orcontract, a report of the mechanical test results and thechemical composition limits shall be furnished.TABLE 1 Sheet ThicknessASpecified Thickness Minim
