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...
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...
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...
My customer requires a UT examination on all rolled plate and formed heads. Per ASME SA-435, the range of thickness is from .500 and above. I have a shell that is .375" and is being rolled and need to have it UT examined. I am being told that it cannot be done per this requirement. I cannot...
Hello, I am in section 9 of ASME and am trying to determine the types of testing that is required for a new weld procedure. Maybe I have over looked something, but to me it is not clear on the types of teating required. Can someone please get me going in the right direction. Thanks all

Does anyone know where I may be able to find some acceptance criteria for using ammonium persulfate on arc burns on pressure vessel per ASME Code. I did find in Section 8(Nonmandatory Appendix K)directions for thier use, but not sure what results are acceptable.
Thanks, John
Goodmorning to all, I have been looking in ASME Sec. 8 Diiv. 1 for reference to the allingment of shell to shell over all, end to end. I have three shell's put together and have a deviation in the measurement. I have a string measured at 4" at each end and at one of the middle seam's I have...
My client is requiring the material for the pressure vessel that we are fabricating not to be from third world countries. My question is, what is considered to be a third world country?
Thanks

I have vessel with internals crossing the girth seam. My customer is ok with performing the UT. I have been told that I have to watch out because there is a code case that is involved but they could not direct me to it or what it says. My vessel is carbon steel (SA-516-70) and is 1/2" in...
I have a customer’s spec. asking for a Magnetic particle test to be performed on the external surface of dished heads in the knuckle radius. I am using a 16" elliptical head with a 2" S.F. Is this head considered to be a dished head and if so, should it have been done by the manufacture.
I have a vessel where the shell was rolled and welded and U-stamped. My question is that this vessel will be going to heat treat and it is 2" thick, the U2A shows that the shell was Impact tested. What do I need to do on my part for Impact testing after HT. Should i have received a production...
I am building an ASME Sec 8 vessle that is equiped with two manholes w/covers. One is located in the head and one in the shell. These manholes were purchased from a vendor of ours and we received them without a data report. I am being told by the vendor that per UG-11 the data reports are not...
I have a vessle that the customer has asked for "NDE: Per Code- Impact & Hardness testing, No PWHT". Low temp Carbon Steel A350LF2 Class 1 flanges and A333 GR6 for the shell and nozzles. My question is: Per the code do I need to perform a Hardness test after fabrication?
Thanks
JM
