ASTM A760/A760M-25

Annotation of standard text ASTM A760/A760M-25 :

This specification covers the standard requirements for corrugated, metallic-coated steel pipes intended for use in sewers, storm water drainage, underdrains, culverts construction, and similar other uses. These pipes are not normally used for the conveyance of sanitary or industrial wastes. This specification however does not include requirements for bedding, backfill, or the relationship between earth cover load and sheet thickness of the pipe. The steel sheet used for the pipes, coupling bands, and steel inserts shall be formed from zinc-coated sheet, aluminum-coated sheet, aluminum-zinc alloy-coated sheet, zinc-aluminum-mischmetal alloy-coated sheet, or zinc and aramid fiber composite coated sheet. The rivets used in riveted pipes shall be of the same material as the base metal specified for the corrugated sheets and shall be thoroughly galvanized or sherardized. Bolts, nuts, and other threaded items used with joining systems shall be zinc coated by hot dip processing, electroplating, or mechanical processing. The pipes shall be fabricated in full circular cross section with either annular or helical corrugations while the seams shall be spot welded in such a manner that they will develop the full strength of the pipe and not affect the shape or nominal diameter of the pipe. A rational analysis or a suitable physical test shall be performed to determine the specified structural properties of the joining systems such as shear, moment, and tensile strengths.
