The ASME Impact Test Requirement article provides you with information about impact test requirements in pressure vessel design and construction.Let's say,you have a pressure vessel under design,process and construction has not started yet.Based on results for this questionWhat are the ASME rules for toughness testing?What are the ASME rules for toughness testing?The rules of ASME Section VIII, Divisions 1 and 2 may require toughness testing to be performed to demonstrate the suitability of the vessel for service at the designated minimum design metal temperature (MDMT),or may provide several options for exemption from toughness testing under qualifying conditions.Impact Testing and Toughness Requirements for Pressure results for this questionWhat are the requirements for impact testing?What are the requirements for impact testing?2.The impact test requirements (number and location)in Table 323.3.1 are performed after a WPS has been impact qualified.The applicable thickness range for the WPS per Section IX should include the thickness range for impact testing per Table 323.3.1.323.3.1 General.When impact testing is requiredB31.3 and ASME Section IX QW 403.6 impact test requirement

ASME Impact Test Requirement.The ASME Impact Test Requirement article provides you information about impact test requirement in pressure vessel design and construction.Suggest you have pressure vessel under design process and construction has not started yet.Based ASME impact test requirement you need to make assessment to see either your pressure vessel is exempted from impact testingASME reviews test requirements for pipes,fittings,flangesIf an alloy is listed as belonging to Curve C,its thickness is 3.5 in.,and the MDMT is 60,it is above the curve and does not need an impact test.If a similar item has an MDMT of 40,it is below the curve and it does need an impact test.B31.3 and ASME Section IX QW 403.6 impact testb)As i know As per B 31.3 Table 323.3.1 A 5 says:Impact test requirement thickness qualification T/2 to T+6 mm for the Thickness T.I e i need to carry one impact test on for the base metal range T/2 to T+ 6.Example for 5 mm sample (impact test coupon) :2.5 to 10

If the code of construction is B31.3,you follow the specific requirements for WPS impact qualification.If the requirements for impact qualificatiB31.3 talk about impact test qualification range not thickness qualification rang QW 403.6 talk about only thickness qualification i e when yMaybe I did not make myself clear.First you review B31.3 to determine the extent of impact testing base material and fabrication welds.Next,youmandmm,All your numbers are making my head spin.Read what metengr has written and then come back and explain why you are impact testing 3 mmDekDee,How come you aren't throwing interpretations 4-17 and 24-29 at metenger?!?So shall it be written,so shall it be done.Metengr,I ask because I wrote the same thing and was crucified by many members of this forum LinkKeep up the good work David,It pays to be in good company.I sometimes forget to recommend review of interpretations.Being on BPV I standards comDavid,The important thing to recognise is the material thickness range given in B31.3 takes precedence over ASME IX as clearly stated in the intProduction Impact Tests ASME VIII,Div.1Dec 20,2005ASME VIII-1 impact test requirements of UG-20 (f) and UCS See more resultsCharpy impact testing requirements - ASME (mechanical

Jun 21,2012·You can always impact test qualify a WPS at a temperature lower than mandated under the curves but remember that the thickness range for qualification can well be more restrictive under B31.3 than under ASME IX.You can make the root with GTAW with ER70S-2 or -6 and the fill passes with 7018 to easily meet -20 F,B31.3 impact requirements.Impact Test Customer Specification versus ASME Code·EXAMPLE 1 Impact Testing ASME Section VIII,Division 1 para.
