X2.3. It shall be permissible to furnish pipe having other dimensions provided that such pip pipee com compli plies es wit with h all oth other er req requir uiremen ements ts of thi thiss specification. Supplementary requirements of an optional nature are provided and shall apply only when specified by the purchaser. NOTE 1—The dimensionless designators NPS (nominal pipe size) [DN (diameter nominal)] have been substituted in this specification for such traditional traditi onal terms as “nomi “nominal nal diame diameter, ter,”” “size, “size,”” and “nom “nominal inal size. size.”” NOTE 2—The term nominal wall thickness has been assigned for the purpose of convenient designation, existing in name only, and is used to distinguish it from the actual wall thickness, which may vary over or under the nominal wall thickness.

S1. Flattening Test, Test, Seamless Pipe S1.1 A test spec S1.1 specime imen n at least least 21 ⁄ 2 in. [60 mm] in length shall be flattened cold between parallel plates in two steps. During the first step, which is a test for ductility, except as allowed by S1.3, S1.4, and S1.5, no cracks or breaks on the inside, outside, or end surfaces shall be present before the distance between the plates is less than the value of H calculated calculated as follows: H 5 ~ 1 1 e ! t / ~ e 1 t / D !

S1.2 Durin During g the second step, which is a test for soundness, soundness, the flattening shall be continued until the test specimen breaks or the opposite sides of the test specimen meet. Evidence of laminated or unsound material that is revealed during the entire flattening test shall be cause for rejection. S1.3 S1. 3 Surface Surface imp imperf erfecti ections ons in the tes testt spe specim cimen en bef before ore flattening, but revealed during the first step of the flattening test, shall be judged in accordance with the finish requirements in Section 12 12..

S1.4 Superficial ruptures as a result of of surface imperfections shall not be cause for rejection. S1.5 S1. 5 For pipe pipe with a D-to-t ratio ratio less than 10, because the strain imposed due to geometry is unreasonably high on the inside surface at the 6 and 12 o’clock locations, cracks at such locations shall not be cause for rejection. S1.6 S1. 6 One test shall be mad madee on test spe specime cimens ns taken from one length of pipe from each lot of each pipe size. A lot shall cont co ntai ain n no mo more re th than an on onee he heat at,, an and d at th thee op opti tion on of th thee manufacturer shall contain no more than 500 lengths of pipe (as initially cut after the final pipe-forming operation, prior to any further cutting to the required ordered lengths) or 50 tons [45 Mg] of pipe.

APPENDIXES (Nonmandatory Information) X1. DEF DEFINITI INITIONS ONS OF TYPES OF PIPE

Type F, Furn Furnaceace-Butt Butt-W -Welde elded d Pipe Pipe,, Con Continu tinuous ous-X1.1 Type Welded Pipe—Pipe produced in multiple lengths from coiled skelp and subsequently cut into individual lengths, having its longitudinal butt joint forge welded by the mechanical pressure develo dev eloped ped in rol rollin ling g the hot hot-fo -forme rmed d ske skelp lp thr throug ough h a set of round pass welding rolls.

X1.2 Type E, ElectricElectric-Resista Resistance-W nce-Welded elded Pipe—Pipe produced duc ed in sin single gle len length gths, s, or in mul multip tiple le len length gthss fro from m coi coiled led skelp and subsequently cut into individual lengths, having a

longitudinal butt joint wherein coalescence is produced by the heat obtained from resistance of the pipe to the flow of electric current in a circuit of which the pipe is a part, and by the application of pressure. X1.3 Type S, Seamless Pipe —Pipe made without a welded seam. It is manufactured by hot working steel and, if necessary, by subsequently cold finishing the hot-worked tubular product to produce the desired shape, dimensions, and properties.

A53/A53M − 12 TABLE X2.4 Ta Table ble of Minimu Minimum m Permiss Permissible ible Wall Thickn Thicknesses esses on Inspec Inspection tion for Pipe Specified Wall Thickn Thicknesses esses

NOTE 1—The following equation, upon which this table is based, shall be applied to calculate minimum permissible wall thickness from specified wall thickness: t s × 0.875 = t m

where: t s = specified wall thickness, in. [mm], and t m = minimum permissible wall thickness, in. [mm]. The wall thickness is expressed to three [two] decimal places, the fourth [third] decimal place being carried forward or dropped in accordance with Practice E29 Practice E29.. NOTE 2—This table is a master table covering wall thicknesses available in the purchase of different classifications of pipe, but it is not meant to imply that all of the walls listed therein are obtainable under this specification.
