Description

This specification covers corrugated steel pipe (CSP) intended for use for storm water damage, underdrains, the construction of culverts, and similar uses. Pipe covered by this specification is not normally used for the conveyance of sanitary or industrial wastes. The steel sheet used in fabrication of the pipe has a protective metallic coating of zinc (galvanizing), aluminum Type 2, 55 percent aluminum-zinc alloy, zinc-5 percent aluminum-mischmetal alloy, or aluminum Type 1.

Steel sheet with zinc and aramid fiber composite coating may be specified for fabrication of pipe. Pipe made from sheet with this composite coating is always furnished with an asphalt coating. Therefore, the requirements in this specification should be considered as applying to semi-finished pipe; the finished pipe must include provisions of M 190.

This specification is technically identical to ASTM A 760/A 760M-01a, except that zinc and aramid fiber composite coating has been removed; aluminum is now distinguished between Type 1 or Type 2 coating. Notes have been added.
