Scope1.1 This specification covers composite corrugated steelpipe, intended for uses such as storm water drainage, sani

3、tarysewers, underdrains, construction of culverts, and similar uses.The composite material used in fabrication of the pipe consistsof a three-layer polymer protective coating on both sides of asteel sheet core. The three layers consist of an inner layer offusion-bonded epoxy on the steel surface, an

4、 intermediate layerof polyethylene adhesive, and an outer layer of high-densitypolyethylene.1.2 The three-layer polymer coating protects the base metalagainst corrosion or abrasion, or both. Severe environments arelikely to cause corrosion problems to accessory items such ascoupling band hardware un

Additional protection for composite steel pipe isavailable by use of coatings applied after fabrication of the pipeas described in Specification A 849.1.3 This specification does not include requirements forbedding, backfill, or the relationship between earth

The dimensions of the corru-gations shall be in accordance with Table 2 for the nominal sizeindicated on the order. If the depth measurement o

37、he depth ofone or a few corrugations. If such measurement indicates insufficientdepth, application of the requirements in Table 3 provides for acceptancewhere greater depth of some corrugations compensates for lack of depthof others. These measurements would normally be made at one locationbetween t
