Where the wall thickness lies between two values shown in Table 2, the minimum elongation value shall be determined by the following equation: rade where: E t ‘elongation in 2 in, (50 mm), %, and actual thickness of specimen, in. 84 The test specimen taken across the weld shall show a tensile strength not less than the minimum tensile strength specified for the grade of pipe ordered. This test will not be required for pipe under NPS 8 in outside diameter. 9. Flattening Test 9.1 A specimen at least 4 in, (102 mm) in length shall be flattened cold between parallel plates in three steps with the ‘weld located either 0° or 90° from the line of direction of force as required in 9.2. During the first step, which is a test for ductility of the weld, no cracks or breaks on the inside or outside surfaces shall occur until the distance between the plates is less than two thirds of the original outside diameter of the pipe. As a second step, the flatening shall be continued. During the second step, which is a test for ductility exclusive of the weld, no cracks or breaks on the inside or outsis surfaces shall occur until the distance between the plates is less than one third of the original outside diameter of the pipe but isnot less than five times the wall thickness of the pipe. During. the third step, which is a test for soundness, the flattening shall bbe continued until the specimen breaks or the opposite walls of the pipe meet. Evidence of laminated or unsound material or of incomplete weld that is revealed during the entire flattening test shall be cause for rejection. 9.2 For pipe produced in single lengths, the flattening test specified in 9.1 shall be made on both crop ends cut from each TABLE 2 Computed Minimum Values ‘wal thctnesn me longaton 2 in (60 ma), Fn ‘Grade A (Grae B Rena gamm 35.00 30.00 (0281) (7.14 rm) 3325 20 (0250) (6.35 mm) 3180 2100 ‘he (0219 (5.56 ro) pars 0 (0188) (4.76 mm) 2500 2400 ‘5 (0.186) (3.97 rom) 2025 50 Ye 0125) (3.10 mm) 2450 200 Ys (0004) (2.38 ren) nis 350 24.00, 20STD-ASTM AL3S-ENGL 199% MM 0759510 OLOL44S Ob) mm qh A135 length of pipe. The tests from each end shall be made alternately with the weld at 0° and at 90° from the line of direction of force. For pipe produced in multiple lengths, the flattening test shall be made on crop ends representing the front and back of each coil with the weld at 90° from the line of direction of force, and on two intermediate rings representing ‘each coil with the weld 0° from the line of direction of force. 9.3 Surface imperfections in the test specimen before flattening, but revealed during the first step of the flattening test, shall be judged in accordance with the finish requirements in Section 15 9.4 Superficial ruptures as a result of surface imperfections shall not be cause for rejection. 10.

This generally involves breaking the corners. 142 Ends, Plain End Pipe—Unless otherwise specified, plain end pipe for use with the Dresser or Dayton type coupling shall be reamed both outside and inside sufficiently 1 remove all burrs. Plain end pipe for welding shall be beveled on theSTD-ASTH ALSS-ENGL 1996 MM 0759510 ObOb449 TTS mm ih A135 ‘outside to an angle of 30° with a tolerance of +5° and ~0° and ‘with a width of flat at the end of the pipe of ie * Yaa in. (1.6 +0.8 mm). When material is ordered beveled to any other than a 35° angle, it should be understood that the angle is to be ‘measured from a line drawn perpendicular to the axis of the pipe. This me:ins that a greater amount of material is removed with a 60° angle than with a 35° angle. Pipe shall be sufficiently free from indentations, projections, or roll marks for a distance of 8 in. (203 mm) from the end of the pipe 10 ‘make a tight joint with the rubber gasket type of coupling. All plain end pipe intended for Dresser or Dayton type joints or for welding, sizes 10% in, (273 mm) and smaller in outside diameter, shall be not more than 42 in. (0.8 mm) smaller than the nominal outside diameter for a distance of 8 in. (203 mm) from the end of the pipe and shall permit the passing for a distance of 8 in.

(0.8 mm) smaller than the ‘nominal outside diameter for a distance of 8 in. (203 mm) from the end of the pipe and shall permit the passing for a distance of 8 in, (203 mm) of a ring gage which has a bore ¥42 in. (2.4 mm) larger than the nominal outside diameter of the pipe. 143 Ends, Threaded Pipe—Each end of threaded pipe shall be reamed to remove all burrs. All threads shall be in accordance with the American National Standard Pipe Threads (Note 6) and cut so as to make a tight joint when the pipe is tested at the mill to the specified internal hydrostatic pressure.

Finish 15.1 The finished pipe shall be reasonably straight and free of injurious defects. Defects in excess of 12.5 % of the nominal ‘wall thickness shall be considered injurious. 152 Repair by Welding—Injurious defects in the pipe wall, provided their depth does not excced one third the specified ‘wall thickness, shall be repaired by electric welding. Defects in the welds such as sweats or leaks, unless otherwise specified, shall be repaired or the piece rejected at the option of the ‘manufacturer. Repairs of this nature shall be made by completely removing the defect, cleaning the cavity, and then electric welding, 15.3 All repaired pipe shall be retested hydrostatically in accordance with Section 10. 16, Number of Tests 16.1 One longitudinal tension test shall be made on one length (Note 8) from each lot of 400 lengths or fraction thereof of each size under NPS 8 and one transverse body and one transverse weld tension test on one length from each lot of 200 lengths or fraction thereof of each size NPS 8 to NPS 20 and ‘on one length from each lot of 100 lengths or fraction thereof ‘of each size over NPS 20 to NPS 30. When taken from the skelp, the number of tests shall be determined in the same manner as when taken from the finished pipe. Nore 8—Length is defined as the length as ordered, except that inthe ‘ase of orders for cut lengths shorter than single random, the term lot shall, ‘apply othe lengths as rolled, prior to cutting to the required shor lengths 162 If any test specimen shows defective machining or develops flaws not associated with the quality of the steel or the welding, it may be discarded and another specimen substituted, 16.3 If the percentage of elongation of any tension test specimen is less than that specified in 8.1 and any part of the fracture is more than % in. (19.0 mm) from the center of the ‘gage length of a 2-in. (50-mm) specimen, as indicated by scribe scratches marked on the specimen before testing, the specimen ‘may be discarded and another substituted. 16.4 The flattening test specified in Section 9 shall be made ‘on both crop ends cut from each length of pipe. When pipe is produced in multiple lengths, flattening tests are required on the crop ends from the front and back ends of each coil and on two intermediate rings representing each coil 16.5 Each length of pipe shall be subjected to the hydrostatic test specified in Section 9. 17. Retests 17.1 If the results of the tension tests of any lot do not conform to the requirements specified in Section 8, retests of two additional lengths from the same lot shall be made, each of, which shall conform to the requirements specified. 17.2 If any section of the pipe fails to comply with the requirements of 9.1, for pipe produced in single lengths other sections may be cut from the same end of the same length until satisfactory tests are obtained, except that the finished shall not be shorter than 80 % of its length after the init cropping; otherwise, the length shall be rejected. For pipe produced in multiple lengths, retests may be cut from each end of each individual tength in the multiple; such tests shall be ‘made with the weld altemately 0° and 90° from the line of direction of force.STD-ASTH AL3S-ENGL 1996 MM 759510 Ob0b4S0 727 mm Gh A135 18. Test Specimens and Methods of Testing 18.1 The test specimens and the tests required by these specifications shall conform to those described in Test Methods and Definitions A 370. 18.2 The longitudinal tension test specimen shall be taken from the end of the pipe, or by agreement between the ‘manufacturer and the purchaser may be taken from the skelp, at a point approximately 90° from the weld, and shall not be flattened between gage marks. The sides of each specimen shall, be parallel between gage marks 18.3 Transverse weld test specimens shall be taken with the weld at the center of the specimen. Transverse body test specimens shall be taken opposite to the weld. All transverse test specimens shall be approximately 1/4 in, (38.1 mm) wide in the gage length and shall represent the full wall thickness of the pipe from which the specimen was cut 184 All specimens shall be tested at room temperature. 19. Inspection 19.1 The inspector representing the purchaser shall have free entry, at all times while work on the contract of the purchaser is being performed, to all parts of the manufacturer's ‘works that concern the manufacture of the material ordered ‘The manufacturer shall afford the inspector, without charge, all reasonable facilities to satisfy him that the material is being furnished in accordance with this specification, AIL tests (except check analysis) and inspection shall be made at the place of manufacture prior t0 shipment, unless otherwise specified, and shall be so conducted as not to interfere unnecessarily with the operation of the works. 20, Rejection 20.1 Bach length of pipe received from the manufacturer ‘may be inspected by the purchaser and, if it does not meet the requirements of this specification based on the inspection and {est method as outlined in the specification, the length may be rejected and the manufacturer shall be notified. Disposition of rejected pipe shall be @ matter of agreement between the ‘manufacturer and the purchaser. 20.2 Pipe found in fabrication or in installation to be unsuitable for the intended use, under the scope and requirements of this specification, may be set aside and the manufacturer notified.
