Designation:E222313Standard Practice forExamination of Seamless,Gas-Filled,Steel PressureVessels Using Angle Beam Ultrasonics1This standard is issued under the fixed designation E2223;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This practice describes a contact angle-beam shear waveultrasonic technique to detect and locate the circumferentialposition of longitudinally oriented discontinuities and to com-pare the amplitude of the indication from such discontinuitiesto that of a specified reference notch.This practice does notaddress examination of the vessel ends.The basic principles ofcontact angle-beam examination can be found in PracticeE587.Application to pipe and tubing,including the use ofnotches for standardization,is described in Practice E213.1.2 This practice is appropriate for the ultrasonic examina-tion of cylindrical sections of gas-filled,seamless,steel pres-sure vessels such as those used for the storage and transporta-tion of pressurized gasses.It is applicable to both isolatedvessels and those in assemblies.1.3 The practice is intended to be used following anAcoustic Emission(AE)examination of stacked seamlessgaseous pressure vessels(with limited surface scanning area)described in Test Method E1419.1.4 This practice does not establish acceptance criteria.These are determined by the reference notch dimensions,which must be specified by the using parties.NOTE1Background information relating to the technical require-ments of this practice can be found in the references sited in Test MethodE1419,Appendix X1.1.5 Dimensional values stated in inch-pound units are re-garded as standard;SI equivalents,in parentheses may beapproximate.1.6 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 limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2E213 Practice for Ultrasonic Testing of Metal Pipe andTubingE543 Specification for Agencies Performing NondestructiveTestingE587 Practice for Ultrasonic Angle-Beam Contact TestingE1316 Terminology for Nondestructive ExaminationsE1419 Practice for Examination of Seamless,Gas-Filled,Pressure Vessels Using Acoustic EmissionE2192 Guide for Planar Flaw Height Sizing by Ultrasonics2.2 ASNT Documents:3Recommended Practice SNT-TC-1A for Personnel Qualifi-cation and CertificationANSI/ASNT-CP-189 Standard for Qualification and Certifi-cation of Nondestructive Testing Personnel2.3 AIA Document:NAS-410 Nondestructive Testing Personnel Qualificationand Certification43.Terminology3.1 Terminology relating to this practice for angle-beamshear wave ultrasonic examination is defined in TerminologyE1316.4.Summary of Methodology4.1 An ultrasonic pulse-echo contact angle-beam,shearwave technique with the beam directed circumferentially isused to locate surface breaking discontinuities in the cylindri-cal wall of a pressure vessel.The amplitude of the reflectedsignal from the discontinuity is compared to that of a knownreference notch.Scanning is performed in both clockwise andcounter clockwise directions to detect and confirm the positionof the discontinuity identified in the AE examination report.1This practice is under the jurisdiction of ASTM Committee E07 on Nonde-structive Testing and are the direct responsibility of Subcommittee E07.06 onUltrasonic Method.Current edition approved June 1,2013.Published June 2013.Originallyapproved in 2002.Last previous edition approved in 2012 as E2223-12.DOI:10.1520/E2223-13.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available fromAmerican Society for Nondestructive Testing(ASNT),P.O.Box28518,1711 Arlingate Ln.,Columbus,OH 43228-0518,http:/www.asnt.org.4Available from Aerospace Industries Association of America,Inc.(AIA),1000Wilson Blvd.,Suite 1700,Arlington,VA22209-3928,http:/www.aia-aerospace.org.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.Significance and Use5.1 The purpose of this practice is to provide a procedure forlocating,detecting and estimating the relevance of longitudi-nally oriented crack-like discontinuities which have beenpreviously indicated by AE examination.5.2 This practice may be used for a pressure vessel that issituated in such a way as to limit access to the vessels wall.Typical examples include tube trailers and gas tube railroadcars.S
