My mother company in Kentucky has the "U" "R" "S" (among others)I am located in Texas, we have a boiler repair job we are bidding on that consist of replacing tubes with new, but will have to cut and re-weld piping welded directly to boiler. Can the TX office use the "S" stamp that is assigned...
can anyone direct me to a industry publication or practice that would tell me what is the norm for acceptable weld rejection percentage for FEILD. I am hearing 5% to 7% but seems a bit high to me.
the original manufacture is not in business (of course) and the equipment is going into a third world country. I like Duwe6 idea of Non conformace i will pursue that avenue thanks.
Good mornign all, question...we are trying to change the service of existing equipment to a high H2s service which wil require us to PWHT the SA516-70 material. the original data sheet and service did not require PWHT. what should i be preprared for? I understand we will have to be NBIC compliant,
Sorry, you are correct, let me re-phrase
Does anyone have a clear understanding of progressive sampling for examintion 341.3.4 (F).
I understand this as
during sampling you have one bad weld
you shoot two tracers 341.3.4(a)
if any of the tracers are bad 341.3.4(c) you shoot two more tracers...

one trace is bad 341.3.4(c)
you shoot two more tracers then
you repair those items until...
Metenger, good advice, and no we have not started any fabrication yet so I will propose your idea of 309 PWHT then 304,
once again ENG-TIPS is the greatest resourse for our industry on the internet
genteleman i have a question, i am building numerouse reators I will use one as an example, we are using SA387 GR.11 CL2 (P4) with a SS304 clad overlay (1/8th). I have concerns about sensitizing ss304 at PWHT temperature. should i be concerned or Austenitic stainless steels which tend to...

Can anyone direct me to the actual paragraph that gives the minimum weld reinforcement for ASME B31.3 normal fluid piping. I have already been to Table 341.3.2 and am having a little interpretation problem, using Symbol "L" height of reinforcement in any plane through the weld shall be with in...
Just an FYI I heard back from Tom Monroe
State of Oklahoma Chief Boiler Inspector/Director his reply to my e-mail is as follows
"The vessels do not have to be registered with the National Board. Our laws only requires they be ASME constructed."
