I assumed as much after digging. Thanks for the reply.

Trying to find the maximum allowed radial clearance between vessel hole and nozzle outside diameter. Ie, the max gap between the drum shell and a nozzle welded with a combination groove/fillet welds from both sides. I did find a requirement in PW.16.6 that refers to figure PW.16.1 (AA) which is...

I see it now with Sect VIII Div 1 UCS 66, B31.3 in 323, b31.1 124.1. B31T and non mandatory appendix VIII. Cant find anything in Sect 1

I am studying ASME Sect IX. Probably a dumb question here but QW 171.1 reads "toughness tests shall be made when required by referencing codes...." My career has been mostly limited to the ASME Sect 1 and B31.1 code. I cant say as I have ever ran across a specific instance where it was required...

Thanks David. Found it.

Trying to figure out the essential variable "A"# for E7010-P1. Ive compared the analysis from both the spec in sect 2 (SFA.5.5) and from a sample test report from Lincoln (pipeliner 7p+) and the analysis doesnt fit any A number on the table. The nickel(1.00max sect 2, typ 0.58-0.90 from the mfr)...

Reviewing uptated 2021 sect I mandatory appendix VIII I cannot not find the HB calc for preheating/postheating. Previous editions used 6T. SB is addressed in all areas (SB/HB/GCB) and HB regarding PWHT.

Thanks dekdee. It would seem that consulting with a weld engineer in 95% of these threads would have merit. I discuss every move I make with a weld engineer. I just like to be somewhat informed ahead of time.

I am working on a procedure to repair a branch connection of an extruded nozzle connection off a manifold to a feeder pipe. Header pipe A53 B. Feeder connections were once SA209-T1a and have at some point been switched out to T22. The failure is some distance away from the header into the...

Thanks guys...

Ive been tasked with reviewing a boiler repair performed several years ago by a well established vendor. Replacing several boiler tubes in several different boiler sections. Header/tube material garden variety 10" sch 120 SA 106 B/ 2" 120mw SA 178A. Nothing special about this configuration...

Thank you. Thats how I assumed it would work. I have another question. 1 of two fabricators chose to use ER70S-6 and the other ER70S-2. I would have expected both fabricators to use ER70S-2. Is one or the other (ER70S-2 VS ER70S-6) more or less likley to be in compliance with A-1 chemistry?

I have a client requesting that I confirm our vendor can comply with the following requirement: "Mild carbon steel filler metals with ASME Section II Part C composition ranges that can extend beyond the ASME Section IX Table QW-442 A-1 chemistry limits (i.e. ER70S-6, E7XT-1, etc.) must be...

We are building several carbon steel tube panels (upper/lower header joined with boiler tubes) and the client is asking for final hardness testing. Nothing special about the project. ASME Sect I. Header pipe SA 106C, sa 51670 end plates and SA 192 finned tubes. PWHT per pw.39 for P1 materials I...

Thanks guys. An exemption of requirements based on current addenda vs original addenda does make sense but for the life of me I cannot locate the actual verbiage that allows it. I have searched NBIC and the closest I find is in " Material requriements for repairs and alterations sect 3.2.1 (a) "...
