Dear All,
Greetings.
A vessel is being fabricated as per ASME SECTION VIII DIV 1.
a vessel requires PWHT becuase of the Service requirment.
Shell plate material is SA537 CL1 - 36 mm thickness. maaterial is in NORAMALIZED Condition.
MTC is not highlighitng any PWHT( STRESS RELIEVING) done for the test coupons before conducting Mechanical testing.
My Question is - as vessel requires PWHT , how we will confirm the effect of PWHT on mechanical proerties for the base material without conducting PWHT on the test coupon of the shell plate before conducting Mechanical test.
Please give code reference.
Thanks & Regards
Asad Azmi
