Scope*1.1 This specification covers aluminum alloy sheets used in the fabrication of corrugated alumi

3、num pipe intended for use forstorm water drainage, underdrains, culverts, and similar uses. The material is furnished corrugated in cut lengths, and uncorrugatedin coils and cut lengths.1.2 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the

4、 text, the SI unitsare shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be usedindependently of the other. Combining values from the two systems may result in nonconformance with the standard.1.3 This standard does not purport to address all

5、 of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use.2.

39、 impact itsuse.the use of this standard. (May 1, 2015.)(1) Deleted the reference to the helical (corrugation) for the 3004H34 alclad alloy in Section 7. 3004H32 is the only temper beingused by the fabricators for helical corrugated aluminum pipe.(1) Revised subsection 7.1(2) Deleted the 0.036 specif

40、ied thickness from Table 1. This thickness of sheet is not being used.(3) Deleted the 6 by 1in. and 150 by 25 mm corrugation from Table 2. this is an unstable corrugation in aluminum and has notbeen fabricated for many years.TABLE 4 Corrugated Sheet Lip DimensionsNominal CorrugationSizeLip Dimension
