美标紧固件热浸锌标准
美标紧固件热浸锌标准通常按照ASTM A53进行。

ASTM A53是美标无缝钢管的标准，其中规定了热浸锌的要求。

热浸锌是一种金属表面处理方法，用于提高紧固件的防腐蚀能力。

在热浸锌过程中，将紧固件放入高温的锌液中浸泡一定时间，使其表面形成一层锌层，起到保护和装饰的作用。

根据ASTM A53标准，美标紧固件热浸锌的厚度要求通常与紧固件的规格和材质有关。

一般来说，紧固件的热浸锌厚度应不小于0.135盎司/平方英尺（约38克/平方米），但具体的厚度要求需要根据紧固件的具体规格和要求进行确定。

此外，ASTM A53标准还规定了其他方面的要求，如锌层的均匀性、附着性、耐腐蚀性等，以确保热浸锌处理的质量和效果。

需要注意的是，不同的紧固件材质和规格可能对热浸锌的要求有所不同，因此在选择热浸锌处理时，需要结合具体情况进行选择和处理。

for chemical analysis,except for spectrographic analysis,shall be taken in accordance with Practice E 1806.The chemical composition thus determined shall conform to the requirements given in Table 1.6.2If the analysis of either pipe does not conform to the requirements given in Table 1,analyses shall be made on additional pipes of double the original number from the same lot,each of which shall conform to the specified requirements.7.Mechanical Properties 7.1Tension Test :7.1.1For tension tests other than transverse weld tension tests,the yield strength corresponding to a permanent offset of 0.2%of the gage length or to an extension of 0.5%of the gage length under load,the tensile strength,and the elongation in 2in.or 50mm shall be determined,and the tension test results shall conform to the applicable tensile property requirements given in Table 2.7.1.2For transverse weld tension tests,the tensile strength shall be determined,and the tension test results shall conform to the applicable tensile strength requirement given in Table 2.7.1.3Electric-resistance-welded pipe NPS 8[DN 200]or larger shall be tested using two transverse test specimens,one taken across the weld and one taken opposite the weld.7.1.4Transverse tension test specimens shall be approxi-mately 11⁄2in.[38mm]wide in the gage length and shall represent the full wall thickness of the pipe from which the test specimens were cut.7.2Bend Test :7.2.1For pipe NPS 2[DN 50]or smaller,a sufficient length of pipe shall be capable of being bent cold through 90°around a cylindrical mandrel,the diameter of which is twelve times the specified outside diameter of the pipe,without developing cracks at any portion and without opening the weld.7.2.2If ordered for close coiling,the pipe shall stand being bent cold through 180°around a cylindrical mandrel,the diameter of which is eight times the specified outside diameter of the pipe,without failure.7.2.3Double-extra-strong pipe over NPS 11⁄4[DN 32]need not be subjected to the bend test.7.3Flattening Test :7.3.1The flattening test shall be made on welded pipe over NPS 2[DN 50]in extra-strong weight or lighter.7.3.2Seamless Pipe :7.3.2.1Although testing is not required,pipe shall be capable of meeting the flattening test requirements of Supple-mentary Requirement S1,if tested.7.3.3Electric-Resistance-Welded Pipe :7.3.3.1A test specimen at least 4in.[100mm]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 by 7.3.3.2or 7.3.3.3,whichever is applicable.During the first step,which is a test for ductility of the weld,except as allowed by 7.3.5,7.3.6,and 7.3.7,no cracks or breaks on the inside or outside surface at the weld shall be present before the distance between the plates is less than two thirds of the specified outside diameter of the pipe.As a second step,the flattening shall be continued as a test for ductility away from the weld.During the second step,except as allowed by 7.3.6and 7.3.7,no cracks or breaks on the inside or outside surface away from the weld shall be present before the distance between the plates is less than one third of the specified outside diameter of the pipe but is not less than five times the specified wall thickness of the pipe.During the third step,which is a test for soundness,the flattening shall be continued until the test specimen breaks or the opposite walls of the test specimen meet.Evidence of laminated or unsound material or of incom-plete weld that is revealed by the flattening test shall be cause for rejection.7.3.3.2For pipe produced in single lengths,the flattening test specified in 7.3.3.1shall be made using a test specimen taken from each end of each 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.7.3.3.3For pipe produced in multiple lengths,the flattening test specified in 7.3.3.1shall be made as follows:(1)Test specimens taken from,and representative of,the front end of the first pipe intended to be supplied from each coil,the back end of the last pipe intended to be supplied from each coil,and each side of any intermediate weld stop location shall be flattened with the weld located at 90°from the line of direction of force.(2)Test specimens taken from pipe at any two locations intermediate to the front end of the first pipe and the back end of the last pipe intended to be supplied from each coil shall be flattened with the weld located at 0°from the line of direction of force.7.3.3.4For pipe that is to be subsequently reheated through-out its cross section and hot formed by a reducing process,the manufacturer shall have the option of obtaining the flattening test specimens required by 7.3.3.2or 7.3.3.3,whichever is applicable,either prior to or after such hot reducing.TABLE 2Tensile RequirementsGrade AGrade B Tensile strength,min,psi

specimen,calculated using the specified outside diameter of the pipe,or the nominal width of the tension test specimen and the specified wall thickness of the pipe,with the calculated value rounded to the nearest 0.01in.2[1mm 2],andU =specified minimum tensile strength,psi [MPa].BSee Table X4.1or Table X4.2,whichever is applicable,for the minimum elongation values that are required for various combinations of tension test specimen size and specified minimum tensilestrength.7.3.4Continuous-Welded Pipe—A test specimen at least4 in.[100mm]in length shall beflattened cold between parallel plates in three steps.The weld shall be located at90°from the line of direction of force.During thefirst step,which is a test for ductility of the weld,except as allowed by7.3.5,7.3.6,and 7.3.7,no cracks or breaks on the inside,outside,or end surfaces at the weld shall be present before the distance between the plates is less than three fourths of the specified outside diameter of the pipe.As a second step,theflattening shall be continued as a test for ductility away from the weld. During the second step,except as allowed by7.3.6and7.3.7, no cracks or breaks on the inside,outside,or end surfaces away from the weld shall be present before the distance between the plates is less than60%of the specified outside diameter of the pipe.During the third step,which is a test for soundness,the flattening shall be continued until the test specimen breaks or the opposite walls of the test specimen meet.Evidence of laminated or unsound material or of incomplete weld that is revealed by theflattening test shall be cause for rejection. 7.3.5Surface imperfections in the test specimen before flattening,but revealed during thefirst step of theflattening test,shall be judged in accordance with thefinish requirements in Section12.7.3.6Superficial ruptures as a result of surface imperfec-tions shall not be cause for rejection.7.3.7For pipe with a D-to-t ratio less than10,because the strain imposed due to geometry is unreasonably high on the inside surface at the6and12o’clock locations,cracks at such locations shall not be cause for rejection.8.Hydrostatic Test8.1The hydrostatic test shall be applied,without leakage through the weld seam or the pipe body.8.2Plain-end pipe shall be hydrostatically tested to the applicable pressure given in Table X2.2,and threaded-and-coupled pipe shall be hydrostatically tested to the applicable pressure given in Table X2.3.It shall be permissible,at the discretion of the manufacturer,to perform the hydrostatic test on pipe with plain ends,with threads only,or with threads and couplings;and it shall also be permissible to test pipe in either single lengths or multiple lengths.N OTE4—The hydrostatic test pressures given herein are inspection test pressures,are not intended as a basis for design,and do not have any direct relationship to working pressures.8.3The minimum hydrostatic test pressure required to satisfy the requirements specified in8.2need not exceed2500 psi[17200kPa]for pipe NPS3[DN80]or smaller,or2800 psi[19300kPa]for pipe larger than NPS3[DN80];however, the manufacturer has the option of using higher test pressures. For all sizes of seamless pipe and electric-resistance-welded pipe,the hydrostatic test pressure shall be maintained for at least5s.9.Nondestructive Electric Test9.1Type E Pipe:9.1.1Except for pipe produced on a hot-stretch reducing mill,the weld seam of each length of electric-resistance-welded pipe NPS2[DN50]or larger shall be tested with a nondestructive electric test in accordance with Practices E213, E273,E309,or E570.Each length of electric-resistance-welded pipe NPS2[DN50]or larger and produced on a hot-stretch-reducing mill shall be tested with a nondestructive electric test that inpsects the full volume of the pipe in accordance with Practices E213,E309,or E570.9.1.2Ultrasonic and Electromagnetic Inspection—Any equipment utilizing the ultrasonic or electromagnetic principles and capable of continuous and uninterrupted inspection of the weld seam shall be used.The equipment shall be checked with an applicable reference standard as described in9.1.3at least once every working turn or not more than8h to demonstrate its effectiveness and the inspection procedures.The equipment shall be adjusted to produce well-defined indications when the reference standard is scanned by the inspection unit in a manner simulating the inspection of the product.9.1.3Reference Standards—The length of the reference standards shall be determined by the pipe manufacturer,and they shall have the same specified diameter and thickness as the product being inspected.Reference standards shall contain machined notches,one on the inside surface and one on the outside surface,or a drilled hole,as shown in Fig.1,at the option of the pipe manufacturer.The notches shall be parallel to the weld seam,and shall be separated by a distance sufficient to produce two separate and distinguishable signals.The1⁄8-in.[3.2-mm]hole shall be drilled through the wall and perpen-dicular to the surface of the reference standard as shown in Fig.1.Care shall be taken in the preparation of the reference standard to ensure freedom fromfins or other edge roughness, or distortion of the pipe.N OTE5—The calibration standards shown in Fig.1are convenient standards for calibration of nondestructive testing equipment.The dimen-sions of such standards are not to be construed as the minimum sizes of imperfections detectable by such equipment.9.1.4Acceptance Limits—Table3gives the height of accep-tance limit signals in percent of the height of signals produced by reference standards.Imperfections in the weld seam that produce a signal greater than the acceptance limit signal given in Table3shall be considered a defect unless the pipe manufacturer can demonstrate that the imperfection does not reduce the effective wall thickness beyond12.5%of the specified wall thickness.9.2Type S Pipe—As an alternative to the hydrostatic test at the option of the manufacturer or if specified in the purchase order,the full body of each seamless pipe shall be tested with a nondestructive electric test in accordance with Practice E213,E309,or E570.In such cases,each length so furnished shall include the mandatory marking of the letters“NDE.”Except as allowed by9.2.6.2,it is the intent of this nondestruc-tive electric test to reject pipe with imperfections that produce test signals equal to or greater than those produced by the applicable calibration standards.9.2.1If the nondestructive electric test has been performed, the lengths shall be marked with the letters“NDE.”The certification,if required,shall state Nondestructive Electric Tested and shall indicate which of the tests was applied.Also, the letters NDE shall be appended to the product specification number and grade shown on thecertification.9.2.2The following information is intended to facilitate the use of this specification:9.2.2.1The calibration standards defined in 9.2.3through 9.2.5are convenient standards for calibration of nondestructive testing equipment.The dimensions of such standards are not to be construed as the minimum sizes of imperfections detectable by such equipment.9.2.2.2The ultrasonic testing referred to in this specification is capable of detecting the presence and location of significant longitudinally or circumferentially oriented imperfections;however,different techniques need to be employed for the detection of differently oriented imperfections.Ultrasonic test-ing is not necessarily capable of detecting short,deep imper-fections.9.2.2.3The eddy current examination referenced in this specification has the capability of detecting significant discon-tinuities,especially of the short abrupt type.9.2.2.4The flux leakage examination referred to in this specification is capable of detecting the presence and location of significant longitudinally or transversely oriented disconti-nuities.The provisions of this specification only require longitudinal calibration for flux leakage.Different techniques need to be employed for the detection of differently oriented imperfections.9.2.2.5The hydrostatic test referred to in 8.2has the capability of finding imperfections of a size permitting the test fluid to leak through the tube wall and may be either visually seen or detected by a loss of pressure.Hydrostatic testing is notnecessarily capable of detecting very tight through-the-wall imperfections or imperfections that extend an appreciable distance into the wall without complete penetration.9.2.2.6A purchaser interested in ascertaining the nature (type,size,location,and orientation)of imperfections that are capable of being detected in the specific application of these examinations is directed to discuss this with the manufacturer of the tubular product.9.2.3For ultrasonic testing,the calibration reference notches shall be at the option of the manufacturer,and shall be any one of the three common notch shapes shown in Practice E 213.The depth of notch shall not exceed 12.5%of the specified wall thickness of the pipe or 0.004in.[0.1mm],whichever is the greater.9.2.4For eddy current testing,the calibration pipe shall contain,at the option of the manufacturer,any one of the following calibration standards to establish a minimum sensi-tivity level for rejection.9.2.4.1Drilled Hole —The calibration pipe shall contain three holes spaced 120°apart or four holes spaced 90°apart,sufficiently separated longitudinally to ensure separately dis-tinguishable responses.The holes shall be drilled radially and completely through the pipe wall,care being taken to avoid distortion of the pipe while drilling.Dependent upon the nominal pipe size,the calibration pipe shall contain the following hole:NPS DN Diameter of Drilled Hole

greater.9.2.4.3Longitudinal Notch—A notch0.031in.[0.8mm]or less in width shall be machined in a radial plane parallel to the pipe axis on the outside surface of the pipe,to a depth not exceeding12.5%of the specified wall thickness of the pipe or 0.012in.[0.3mm],whichever is the greater.The length of the notch shall be compatible with the testing method.9.2.4.4Compatibility—The calibration standards in the cali-bration pipe shall be compatible with the testing equipment and the method being used.9.2.5Forflux leakage testing,the longitudinal calibration reference notches shall be straight-sided notches machined in a radial plane parallel to the pipe axis.For specified wall thicknesses less than0.500in.[12.7mm],outside and inside notches shall be used.For specified
