ASTM A1042 / A1042M - Specification for Composite Corrugated Steel Pipe for Sewers and Drains
This specification covers composite corrugated steel pipe, intended for uses such as storm water drainage, sanitary sewers, underdrains, construction of culverts, and similar uses. The composite material used in fabrication of the pipe consists of a three-layer polymer protective coating on both sides of a steel sheet core. The composite corrugated steel pipe covered by this specification is classified as Type IC and Type ICS. Type IC pipe shall be fabricated with helical corrugations and a continuous lock seam extending helically from end to end of each length of pipe. Type ICS shall be fabricated with helical corrugations and a continuous helical lock seam extending from end to end of each length of pipe, and with a smooth high-density polyethylene liner thermally bonded to the pipe polymer coating at each interior corrugation crest over the length of the pipe. Types IC and ICS pipe shall conform to the pipe dimensions and sheet thickness. Field joints for each type of composite corrugated steel pipe shall maintain pipe alignment during construction and prevent infiltration of fill material during the life of the installation. The following types of coupling systems shall be permitted: flange type; bell and spigot type; band type with annular corrugations; flat band type; and smooth sleeve type. Specimens cut from production pipe normal to and across the lock seam shall develop the specified tensile strength.
