[MW:33971] Request for Filled Pressure vessel inspection Report

Dear Experts,                         I have recently become an API 510 pressure vessel inspector. But I like to see How ITR's (Inspection Test Report) to be prepared for the vessel inspection. If anyone is done, kindly share filled ITR's for better understanding and few words about the inspection procedure.

Re: [MW:33970] Weldability of A283 Gr C with A573 Gr70

There are certain factors to be considered while selecting the welding consumable. 1. The Tensile strength of the welding consumable shall be higher than the minimum specified Tensile strength of the Base material. 2. If two different grades are welded the welding consumable tensile strength shall be higher than the lowest grade. "> 3. If it is a structural weld and welding to the pressure boundary then low H2 electrode is preferred such as E7018 / E7108-1. 4. If it is between a non pressure part to non-pressure part then  you can prefer E6013 for your requirement and thickness. "> 5. If the Thickness(>25mm) & Carbon equivalent is higher it is preferred to weld with a low H2 electrode such as E7018 Thanks & Regards J.Gerald Jayakumar On Friday, 27 January, 2023 at 11:05:33 am GMT+3, Benaouda Mezrar <mezrarbenaouda4@gmail.com> wrote: ...

It is depending on Design Construction code / Client specification Normally ASME  SEC I , piping,  equipment does not call  for Hardness test .

Re: [MW:33955] how is repair calcualted in piping percantage of RT IS 5%

The acceptable Repair percentage is specified in the Client specification. From your Excel sheet as below. "> From your attached sheet, the Repair percentage is calculated in 2 ways. 1. Joint wise (no of Joints Repair / Total no of Joints RT shoot x 100). 2. RT Film wise ( no of Films Repair / Total no of Films shoot x 100). From the Client specification, you can understand what is the 5% limit.
