Scope

1.1 This specification covers polymer precoated, closed rib steel pipe, intended for use for storm water drainage, under-drains, 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 polymer protective coating over a metallic coating of zinc.

1.2 The polymer precoating provides extra protection of the base metal against corrosion or abrasion, or both, in addition to that provided by the metallic coating. Severe environments are likely to cause corrosion problems to accessory items such as coupling band hardware that does not have a polymer coating unless supplemental protection is provided. Additional protection for polymer precoated 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 rib depth, 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 1019, or in SI units as A 1019M. 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 1019M.

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 limitations prior to use.
