1.1 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 three layers consist of an inner layer of fusion-bonded epoxy on the steel surface, an intermediate layer of polyethylene adhesive, and an outer layer of high-density polyethylene. 1.2 The three-layer polymer coating protects the base metal against corrosion or abrasion, or both. Severe environments are likely to cause corrosion problems to accessory items such as coupling band hardware unless supplemental protection is provided. Additional protection for composite steel pipe is available by use of coatings applied after fabrication of the pipe as described in Specification A 849. 1.3 This specification does not include requirements for bedding, backfill, or the relationship between earth cover load and sheet thickness of the pipe. Experience with drainage products has shown that successful performance depends upon the proper selection of corrugation profile, sheet thickness, type of bedding and backfill, controlled manufacture in the plant, and care in installation. The installation procedure is described in Practice A 798/A 798M. 1.4 This specification is applicable to orders in either inch-pound units as A 1042, or in SI units as A 1042M. Inch-pound units and SI units are not necessarily equivalent. SI units are shown in brackets in the text for clarity, but they are the applicable values when the material is ordered to A 1042M. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use. |
