ASTM A1042 - A 1042M - 04 (2009).pdf

Designation A1042/A1042M – 04 Reapproved 2009Standard Specification forComposite Corrugated Steel Pipe for Sewers and Drains1This standard is issued under the fixed designation A1042/A1042M; the number immediately following the designation indicates theyear of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers composite corrugated steelpipe, intended for uses such as storm water drainage, sanitarysewers, 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 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 unless supplemental protection isprovided. Additional protection for composite steel pipe isavailable by use of coatings applied after fabrication of the pipeas described in Specification A849.1.3 This specification does not include requirements forbedding, backfill, or the relationship between earth cover loadand sheet thickness of the pipe. Experience with drainageproducts has shown that successful performance depends uponthe proper selection of corrugation profile, sheet thickness, typeof bedding and backfill, controlled manufacture in the plant,and care in installation. The installation procedure is describedin Practice A798/A798M.1.4 This specification is applicable to orders in eitherinch-pound units as A1042, or in SI units as A1042M.Inch-pound units and SI units are not necessarily equivalent. SIunits are shown in brackets in the text for clarity, but they arethe applicable values when the material is ordered toA1042M.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory requirements prior to use.2.

Fabrication7.1 General RequirementsPipe shall be fabricated in fullcircular cross section.7.1.1 Type IC pipe shall be fabricated with helical corruga-tions and a continuous lock seam extending helically from endto end of each length of pipe.7.1.2 Type ICS pipe shall be fabricated with helical corru-gations and a continuous helical lock seam extending from endto end of each length of pipe, and with a smooth high-densitypolyethylene liner thermally bonded to the pipe polymercoating at each interior corrugation crest over the length of thepipe. The minimum thickness of the liner shall be 0.020 in.[0.50 mm].7.2 CorrugationsThe corrugations shall be helical asprovided in 7.1.1. The direction of the crests and valleys of thehelical corrugations shall not be less than 60 from the axis ofthe pipe for pipe diameters larger than 21 in. [525 mm], and notless than 45 from the axis for pipe diameters of 21 in. [525mm] and smaller.7.2.1 The corrugations shall form smooth continuouscurves, or curves and tangents. The dimensions of the corru-gations shall be in accordance with Table 2 for the nominal sizeindicated on the order. If the depth measurement of one ormore corrugations is less than the specified minimum depth inTable 2, the depth of all the corrugations between adjacentseams shall be measured and the values in Table 3 forminimum average depth and minimum corrugation depth shallapply.NOTE 1Inspection frequently consists of measurement of the depth ofone or a few corrugations.

The term “outside” refers to the outside surface of the pipe.DAverage of nominal inside radius 0.162 in. [4.1 mm] of outer corrugations and nominal inside radius 0.094 in.

These measurements would normally be made at one locationbetween the seams on a length of pipe.NOTE 2The nominal dimensions and properties for pipe wall corru-gations are given in Practice A796/A796M.7.3 Helical Lock SeamsThe lock seam shall be formed inthe pipe wall near mid-depth.7.3.1 The edges of the sheets within the cross section of thelock seam shall lap as follows, but with an occasional toleranceof −10 of lap width allowable. For the 2-2⁄3 by1⁄2 in. [68 by13 mm], 3 by 1 in. [75 by 25 mm], or 5 by 1 [125 by 25 mm]corrugations, the lap shall be at least5⁄16 in. [7.9 mm]. For the1⁄2 by1⁄4 in. [13 by 6.5 mm] and9⁄16 by3⁄8 in. [15 by 10 mm]corrugations, the lap shall be at least 0.125 in. [3.2 mm].7.3.2 The lapped surfaces shall be in tight contact. Theprofile of the sheet shall include a retaining offset adjacent tothe 180 fold as described in AASHTO T249 of one sheetthickness on one side of the lock seam, or one-half sheetthickness on both sides of the lock seam, at the fabricatorsoption. There shall be no visible cracks in the metal, loss ofmetal-to-metal contact, or excessive angularity on the interiorof the 180 fold of metal at the completion of forming the lockseam. Damage to the polymer coating is subject to repair inconformance with Section 11.7.3.3 Specimens cut from production pipe normal to andacross the lock seam shall develop the tensile strength listed inTable 4, when tested according to AASHTO T249M.7.4 End FinishIf flange type couplings or bands withannular corrugations are to be provided, the pipe ends shall beembedded in a high-density polyethylene flange with dimen-sions as specified in Table 5. If bell and spigot type couplingsare provided, the pipe ends shall be embedded in end deviceswith dimensions suitable for providing mating surfaces. Suchend devices for bell and spigot couplings shall be of high-density polyethylene, polyvinyl chloride, or other suitablepolymer material.8. Pipe Requirements8.1 Types IC and ICS Pipe8.1.1 Pipe DimensionsThe nominal diameter of the pipeshall be as stated in the order, selected from the sizes listed inTable 1. The size of corrugations that are standard for each sizeof pipe are also shown in Table 1. The average inside diameterof circular pipe, shall not vary more than 1 or1⁄2 in. [13mm], whichever is greater, from the nominal diameter whenmeasured on the inside crest of the corrugations.8.1.2 Sheet ThicknessSheet thickness shall be as specifiedby the purchaser from the specified sheet thicknesses listed inTable A1.1, Annex A1.9.
