Standard Weight (Weight per Unit Length) 13.1 A system of standard pipe sizes has been approved by the American National Standards Institute as ANSI B36.10 and. 'B36.19. The standard sizes do not prohibit the production and use of other sizes of pipe produced to the various product specifications referenced in 1.1. (See Note 3.) 13.2 For nonstandard sizes of pipe, the calculated weight per foot shall be determined from the following equation: = CD~iye 0 10,68 (0.02466), = weight, h/t (kg/m), = specified or calculated (from specified inside diameter and wall thickness) outside diameter, in, fmm], and = specified wall thickness, in. (103 decimal places) [mm to 2 decimal places). 13.3 When minimum wall thickness is specified on the purchase order, the calculated weight per foot shail be deter- ‘ined using Eq'1, obtaining from Table X1.1 the nominal wall thickness, t, correspohding to that minimum wall Nore 3—The weights given in the American National Standards and the calculated weights given by Eq 1 are based on the weighs for exzboa steel pipe. The weight of pipe made of ferrite stainless stecls may be up to about 5 % less, and that made of austenitic stainless steel up to about 2% greater than the values given. weng 14, Ends 14.1 Unless otherwise specified, the pipe shall be furnished with plain ends. All burrs at the ends of the pipe shall be removed. 15.

(3.2 mm]. For metal-are welded pipe. with lengths shorter than 10 fi [3.0 ml, this ‘maximum deviation shall be prorated with respect tothe ratio Of the actual length to 10 ft [3.0 m). 16, Repair by Welding 16.1 Repair by welding of defects in seamless pipe (includ- ing centrifugally cast pipe and forged and bored pipe) and of plate defects in welded pipe and, when specifically stated by the product specification, weld seam defects in welded pipe shall be permitted subject to the approval of the purchaser and with the further understanding that the composition of the eposited filler metal shall be suitable for the compositionfh a 999/a 999m being welded, Defects shall be thoroughly chipped or ground cout before welding and each repaired length shall be reheat treated or stress relieved as required by the applicable specifi- cation. Each length of repaired pipe shall be nondestructively tested as required by the product specification. 162 Repair welding shall be performed using procedures and welders or welding operators that have been qualified in accordance with the ASME Boiler and Pressure Vessel Code, Section IX. 17. Retests 17.1 Ifthe results of the certification tests of any lot do not conform to the requitements specified in the individual speci- fication, retests may be made on additional lengths of pipe of double the original number from the same lot, each of which shall conform to the requirements specified. Only one retest of any lot will be permitted. Nonconformance will be cause for the rejection of the lot. 17.2 Any individual length of pipe that meets the test requirements is acceptable. Individual lengths that do not conform to the test requirements may be resubmitted for test provided the reason for nonconformance is established and the nonconforming portion removed. 18, Retreatment 18.1 If individual lengths of pipe selected to représent any 4ot fail to conform to the test requirements, the lot represented may be reheat treated and resubmitted for test. The manufac- turer may reheat treat the pipe, but not more than twice, except with the approval of the purchaser 19, Test Specimens 19.1. Test specimens shall be taken from the ends of finished pipe prior to any forming operations, or being cut to length, 19.2 Specimens cut either longitudinally or transversely shall be acceptable for the tension test : 193. If any test specimen shows flaws or defective machin- ing, the specimen may be discarded and another substituted, 20, Flattening Test Requirements 20.1 Seamless and Centrifugally Cast Pipe—A section of pipe not tess than 2¥4 in. {63 mm] in length shall be flattened cold between parallel piates in two steps. During the first step, which is atest for ductility, no cracks or breaks on the inside, ‘outside, of end surfaces, except as provided for in 20.3.4, shall ‘occur until the distance between the plates is tess than the value of H calculated as follows: A= (trewlet uD) @ where: distance between flattening plates, in, (ram), specified wall thickness, in. [mm], specified outside diameter, outside diameter corre- sponding to specified ANSI pipe size, or outside diameter calculated by adding 2r (as defined above) to the specified inside diameter in. [mm], and ¢ = deformation per unit length (constant fora given grade of steel, 0.07 for medium carbon steel (maximum specified carbon 0.19 % or greater), 0.08 for feritic alloy steel, 0.09 for austenitic steel, and. 0.09 for low-carbon steel (iaximum specified carbon 0.18 9% or less)) During the second step, which is a test for soundness, the flartening shall be continued until the specimen breaks or the opposite walls ofthe pipe meet 202 Welded Pipe—A section of welded pipe not less than 4 in, [100 mi] in length shall be flattened cold between parallel plates in two steps. The weld shall be placed at 90° from the direction of the applied force (at the point of maximum bending). During the first step, which isa test for ductility, no ‘racks or breaks on the inside or outside surfaces, except as Provided for in 20.3.4, shall occur until the distance between ‘the plates is less than the value of H calculated by Eq 2. During the second step, which is a test for soundness, the flattening shall be continued until the specimen breaks or the opposite walls of the pipe meet. 203 Seamless, Centrifugally Cast, and Welded Pipe: 20:3.1 Evidence of laminated or defective material or weld that is revealed at anytime during the entre flattening test shall be cause for rejection 203.2 Surface imperfections not evident in the test speci- ‘men bofore flattening, but revealed during the first step of flattening test, shall be judged in accordance with the finish requirements 20.3.3 Superficial ruptures resulting from surface imperfec- tions shall not be a cause for rejection. 20.3.4 When low D-to-t ratio tubular products are tested, because the strain imposed due to geometry is unreasonably hhigh on the inside surface at the six and twelve o'clock locations, cracks at these locations shall not be cause for rejection if the D-to- ratio is less than 10, 21, Nondestructive Test Requirements 21.1 When required by the applicable product specification ‘or the purchase order, the pipe shall be tested by the hydrostatic test (See 21.2) or by the nondestructive electrical test: (see 213). 21.2 Hydrostatic Test 21.2.1 Except as provided in 21.2.2 and 21.2.3, cach length of pipe shall be tested by the manufacturer to & hydrostatic pressure which will produce in the pipe wall a stress not less than 60 % of the minimum specified yield strength for feritic alloy and stainless steel pipe, or 50% of the specified mini mum yield strength for austenitic alloy and stainless steel pipe and for ferriticfaustentic stainless steel pipe, The test pressure cor stress shall be determined by the following equation: P= 28uDorS = PORE o where: P_ = hydrostatic test pressure in psi {MPal, pipe wall stress in psi or [MPa],eee 1 = specified wall thickness, nominal wall thickness ac- cording to specified ANSI schedule number, or 1.143 times the specified minimum wall thickness, in. [mm], and specified outside diameter, outside diameter corre- sponding to specified ANSI pipe size, or outside diameter calculated by adding 21 (as defined above) 10 the specified inside diameter, in, [mm 2121.1 The hydrostatic test pressure determined by the ‘equation shall be rounded to the nearest 50 psi [0.5 MPa] for pressures below 1000 psi [7 MPa], and to the nearest 100 psi [1 MPa] for pressures 1000 psi [7 MPa] and above. The hydrostatic test may be performed prior to cutting to final length, or prior to upsetting, swaging, expending, bending, or other forming operations. 21.2.2 Regardless of pipe-wall stress-evel determined by 1Bq 3, the minimum hydrostatic test pressure required to satisfy these requirements need not exceed 2500 psi [17.0 MPa for ‘outside diameters (see D in 21.2) of 3.5 in, (88.9 mm] or less, ‘or 2800 psi [19.0 MPa} for outside diameters over 3.5 in. [88.9 mm]. This does not prohibit testing at higher pressures at the ‘option of the manufacturer or as provided in 21.3. 21.2.3 With concurrence of the manufacturer, a minimum hydrostatic test pressure in excess of the requirements of 21.2 or 21.1, or both, may be stated on the order. 21.2.4 The test pressure shall be held for a minimum of 5 s. For welded pipe, the test pressure shall be held for a time sufficient to permit the entire length of the welded seam to be inspected. 21.2.5 The hydrostatic test may not be capable of testing the end portion ofthe pipe. The length of pipe that cannot be tested shall be determined by the manufacturer and, when specified in the purchase order, reported to the purchaser. 213 Nondestructive Electric Test: 21.3.1 Bach pipe shall be examined with nondestructive test in accordance with Practices E213, E309, E426, ot E570. Unless specifically called out by’ the purchaser, the selection of the nondestructive electric test shall be at the option of the manufacturer. Upon agreement between pur chaser and manufacturer, Practice E 273 shall be employed in Addition to one of the full periphery tests. The range of pipe sizes that may be examined by each method shall be subject to the limitations in the scope of the respective practices. 21.3.2 The following information is for the benefit of the ser of this specification: 213.21 The reference standards defined in 21.2.2-21,25 are convenient standards for calibration of nondestructive it i testing equipment. The dimensions of these standards should not be construed as the minimum size imperfection detectable by such equipment If, 24322 The ukraonic tetng (UT) can be peformed to ‘detect both longitudinally and circumferentally oriented de- fects. I should be recognized that different techniques should be used to detect differently oriented imperfections. The f examination may not detect short deep defects. 21.3.2.3 The eddy-current testing (ET) referenced in this specification, (See Practices E 426 and F 308), has the capa- llty of detecting significant discontinuities, especially of the 747 ) a oo9/a soom short abrupt type. The sensitivity of this test decreases with, thickness over 0.25 in. (6 mm). 21.3.2.4 The flux leakage cxamination referred to in this specification is capable of detecting the presence and location of significant longitudinally or transversely oriented discon iuities. However, sensitivity of the test to various types of discontinuities is affected by the calibration, and different techniques should be employed to detect differently oriented imperfections. 21.3.2.5 A purchaser interested in ascertaining the nature (type, size, location, and orientation) of discontinuities that can, bbe detected in the specific application of these examinations should discuss this with the manufacturer of the tubular product. 21.3.3 Time of Examination: 21.3.3.1 Nondestructive testing for specification acceptance shall be performed after all mechanical processing, heat treatments, and straightening operations. This equipment does not preclude additional testing at earlier stages in the process- ing . 21.3.4 Surface Condition: 21.3.4.1 All surfaces shall be free of scale, dirt, grease, paint, and other foreign material that could interfere with interpretation of test results. The methods used for cleaning, and preparing the surfaces for examination shall not be detrimental to the base metal or the surface finish, 21.3.4.2 Excessive surface roughness or deep scratches can produce signals that interfere with the test. 21.3.5 Extent of Examination: 21.3.1 The relative motion of the pipe and the transduc- ex(s), coil(s), or sensor(s) shall be such that the entire pipe surface is scammed, except as in 21.3.5.2. 21.3.5.2 The existence of end effects is recognized, and the extent of such effects shall be determined by the manufacturer, and,-if requested, shall be reported to the purchaser, Other ‘nondestructive tests may be applied to the end areas, subject to agreement between the purchaser and the manufacturer, 21.3.6 Operator Qualifications: 21.3.6.1 The test unit operator shall be certified in accor- dance’ with SNT-TC-1A, or an equivalent recognized and documented standard. 21.3.7 Test Conditions: 213.71 For eddy-current testing, the excitation coil fre~ quency shall be chosen to ensure adequate penetration yet provide good signal-to-noise ratio. 21.372 The maximum eddy-current coil frequency used shall be as follows: (On specie wats up © 0.080 = 100 ite max Cn apectied wal up fo © 80 = 80 kHz mex Gn ape wals uel oer restey han O80 n.~ OKMEmax | 213.73 Ulirasonic—For examination by the ultrasonic method, the minimum nominal transducer frequency shall be 2.00 MHz and the maximum nominal transducer size shall be 15 in. 213.74 If the equipment contains reject notice filter setting, this shall remain off during calibration and testing ‘unless linearity can be demonstrated at the setting 21.3.8 Reference Standards:21.3.8.1 Reference standards of convenient length shall be prepared from a length of pipe of the same grade, size (NPS, or ‘outside diameter and schedule or wall thickness), surface finish ‘and heat treatment conditions as the pipe to be examined. 213.82 For Ultrasonic Testing, the reference 1D and OD notches shall be any one of the three common notch shapes shown in Practice F 213, at the option ofthe manufacturer. The depth of each notch shall not exceed 126% of the specified wall thickness of che pipe or 0.004 in. (0.1 mm}, whichever is % greater, The width of the notch shall not exceed twice the ‘depth, Notches shall be placed on both the OD and ID surfaces. 213.83 For Eddy-Current Testing, the reference standard shall contain, atthe option of the manufacturer, any one of the following discontinuities: 21.3.8.4 Drilled Hole ~The reference standard shall con- tain three or more holes, equally spaced circumferentially around the pipe and longitudinally separated by a sufficient distance to allow distinct identification of the signal from each hole. The holes shall be drilled radially and completely through, the pipe wall, with care being taken to avoid distortion of the pipe while driting. One hole shall be. drilled in the weld, if Visible. Altemately, the producer of welded pipe may choose to drill one hole in the weld and run the calibration standard trough the test coils three times with the weld tured at 120° ‘on each pass. The hole diameter sball be no larger than as follows: NPS Decorator Hole Diameter % 0.039 in [tm shove isto 1 v4 085 in" [34 men] above 1 102 D071 in.

Extrancous signals caused by identifiable causes such as dings, scratches, dents, straightener ‘marks, ctc., shall not be considered noise. The rejection amplitude shall be adjusted to be at least 50 % of full scale of the readout display. 21.3.9.5 If upon any standardization, the rejection ampli. tude has decreased by 29 % (3 dB) of peak height from the last standardization, the pipe tested since the last calibration shall be rejected. The test system settings may be changed, or the transducer(s) coil(s) or sensor(s) adjusted, and the unit restan dardized, but all pipe tested since the last acceptable standard. ization must be retested for acceptance. ~ 213.10 Evaluation of Imperfections: 21.3.10.1 Pipes producing a signal equal to or greater than the lowest signal produced by the reference standard(s) shall be identified and separated from the acceptable pipes. The area producing the signal may be reexamined. 21,3.10.2 Such pipes shall be rejected ifthe test signal was produced by imperfections that cannot be identified or was produced by cracks of erack-life imperfections. These pipes ‘ay be repaired when such repair is permitted by the appli- cable product specification. To be accepted, a repaired pipe ‘oust pass the same nondestructive test by which it was rejected, and it must meet the minimum wall thickness require- ‘ments of the applicable product specification. ‘ 21,3.10.3 If the test signals were produced by visual imper fections such as: scratches; surface roughness; dings; straight ‘ener marks; cutting chips; stel die stamps; stop marks, or pipe reducer ripple. The pipe may be accepted based on visual examination provided that the imperfection is 1ess than 0.004 in. (0.1 mm] or 121% of the specified wall thickness, whichever is greater. "i 21,3.10.4 Rejected pipe may be reconditioned and retested providing that the wall thickness is not decreased to less than that required by the applicable product specification, The ‘outside diameter at the point of grinding may be reduced by the amount so removed. To be accepted, retested pipe shall meet the test requirement, “ 21.3.10.5 If the imperfection is explored to the extent thatit can be identified as non-rejectable, the pipe may be accepted without further test provided that the imperfection docs not ‘encroach on the minimum required wall thickness. 22, Inspection aa 22.1 The inspector representing the purchaser shall have ‘enlcy at all times 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 manv- facturer shall afford the inspector all reasonable facilities #9 satisfy him that the material is being furnished in accordance With this specification. All required tests and inspection shall ‘be made at the place of manufacture prior to shipment, ualess otherwise specified, and shall be conducted so as not 10 interfere unnecessarily with operation of the works.23. Rejection 23.1 Each length of pipe received from the manufacturer may be inspected by the purchaser and, if it does not meet the sequitements of the specification based on the inspection and test method as outlined in the specification, the length may be rejected and the manufacturer shall be notified. Disposition of rejected pipe shall be a matter of agreement between the manufacturer and the purchaser. 23.2 Pipe that fails in any of the forming operations or in the process of installation and is found to be defective shall be set aside and the manufacturer shall be notified for mutual evaluation of the suitability of the pipe. Disposition of such pipe shall be matter for agreement. 24. Certified Test Report 24.1 When specified in the purchase order or contract, the producer of supplier shall fumish a certified test report certi- fying that the material was manufactured, sampled, tested, and inspected in accordance with the specification, including year date, the supplementary requirements, and any other require ments designated in the purchase order or contract, and the results met the requirements of that specification, the supple ‘mentary requirements and the other requirements. A signature or notarizaton is not required on the certified test report, but | the document shall be dated and shall clearly identify the organization submitting the report, (See Note 4.) ors 4—Norwithstnding the absence of a signature or notarization, the organization submiting the Report is responsible forthe contents of the report. | 24.2 I addition, the cerited test report shall inctude the following information and test results, when applicable: 24.2.1 Heat number, 24.22 Heat analysis, 24.2.3 Product analysis if specified or required, 24.2.4 Tensile properties, 24.2.5 Width in the gage length, when longitudinal strip tension test specimens are used, 24.2.6 Bend test acceptable, 24.2.7 Flattening test acceptable, 242.8 Hydrostatic test pressure, 24.29 Nondestructive electric test pressure, 242.10 Impact test results, and 24.2.11 Other test results or information required to be reported by the product specification 243 Test results oF information required to be reported by supplementary requirements, or other requirements designated 1 the purchase order or contract shall be reported but may be reported in a separate document. 1} 24.4 The certified test report shall include a statement of explanation for the eter added to the specification mumber f marked on the tubes (see 25.5) when all of the requirements of the specification have not been completed. The purchaser must cectfy that all requirements of the specification have been completed before the removal ofthe letter (that is, X, Y, or Z). 24.5 A material test report, certificate of inspection, or | Stilar document printed from or used in electronic form from clectronie data interchange (EDI) transmission shall be *sarded as having the same validity as a counterpart printed in i) A 999/a 999m the ‘Upt050,ind, Ovwr3% ODI 0000 0010 = gi © 05, Over 5.01080,inc.
