Good morning, I have a situation where I have existing 6" std wall piping with a 6" 300# flange WN. The new compressor that came in has a 6" 900# flange. I do not have any room for a spool piece (Flange to pipe to flange). I've looked through B31.3 and interpretations and I don't see anything...
Good morning all, I have had a question brought to me about the PQR and the welder that performed the test.
Is it mandatory to write a WPQ for the welder that qualified the PQR?
My initial thought was that all welders must have a WPQ written for there qualification.
But if the welder qualified...
Metenger, I agree with that statement but the key word in your statement is should, I cannot tell them they should. Should is a opinion and shall is a must. As far as the data report, Ill be the one signing off on it and the report will state the nominal for the shell and a minimum for the...
As we know, some helpers are heavy handed and tend to grind the heck out of something when you instructed them to just blend it. Just bleeenndd it. Grrr
Anyways, I have a vessel made from SA-516-70, 2" in thickness with a minimum thickness of 1.8125". The helper ground it down below the minimum...
Im sorry. I dont want to keep dragging this out. One more question. If the weld procedure used was qualified with an equal or more amount of heat treatment time, would that accomidate the testing you are speaking of?
I appreciate your answer, which I’m sure it does affect the material. My question is, where is it in code that states, if it does, that it has violated ASME code? That is all I have to stand on. If it does not violate code, than there goes my argument.
It is made of carbon steel, three nozzles with repads. This vessel as I call it is actually a sphere. Two hemi heads welded together with three nozzles.
Hey all, Ive looking through ASME Section 8 Div. 1 for an answer to my question and have not found anything.
My question is: Can a vessel be heat treated too much?
For instance, im reviewing a vessel package where the vessel wall is .75" in thickness. Not required to be heat treated by code...
For the life of me I can not find any acceptance criteria for porosity in a weld. Section 8 Div. 1 vessel. I have always thought that as long as the cluster is no more than two times the thickness in a 6" length of weld. Now that im trying to firm up what I thought was correct, I can not find it...
Good Afternoon everyone, I am a quality manager at an ASME Section 8 Vessel shop. We have a job in-house that is a small skid with about 8 pipe spools. The job package hit my department and now its my job to adhere to the Code of construction (B31.8). My question is, Are calculations needed on...
