Hello all,
I would like to consult regarding the definition of an "assembly" as per PED 2014/68/EU.
The system I have contains the following pressure equipment:
* Steam Generator (MAWP=5 Barg) - Category III
* Pressure Vessel (MAWP=3 Barg) - Category III
* Piping System with DN<32, piping is...
Hello all,
I have a question regarding a nozzle to shell welding in an ASME "U" vessel.
The weld detail is similar to that shown in ASME VIII-2 Table 4.2.12 detail 3/ASME VIII-1 Figure UW-16.1(z-1) except that there is no bevel in the shell, and the shell is completely straight.
See...
Hello all,
I am facing an issue with a pressure vessel door which need to be replaced.
The pressure vessel was manufactured in accordance with ASME VIII-1 and was hydrostatically tested and the FORM U-1 was signed by the authorized inspector.
The said vessel has a removable door which now need...
Hello all,
I would like to know what is the best way to apply moment acting on a nozzle attached to a pressure vessel.
For example, what is the correct way to apply the moment in the figure below on the nozzle, using Solidworks Simulation...
Hello all,
I'm seeking assistance with interpreting NBIC Part 3.
We have a situation involving a pressure vessel where the original nameplate needs to be removed and replaced with a new one. No other repairs will be conducted.
Paragraph 5.11 stated the If it becomes necessary to remove...
Hello everyone,
In accordance with ASME VIII-1, UW-19(c)(2), for welded stayed constructions involving dimpled plates welded to plain plates, the Maximum Allowable Working Pressure (MAWP) of the dimpled components is determined following the requirements outlined in UG-101.
Referencing U-2(g)...
Hello everyone,
I hope you're all doing well. I'm reaching out because I could use some assistance. I'm trying to create a custom results plot in Solidworks Simulation by generating a .csv file with elements and their respective assigned values.
I vaguely remember accomplishing this in the...
Hello everyone,
I am seeking assistance in finding formulas to calculate the stress and deflection of a flat, rectangular plate. The plate is simply supported along its long edges and free on the short edges, as illustrated in the attached figure.
I have explored resources such as Roark's and...
Hello all,
I would like to seek your insights on the topic of welding non-pressure bearing attachments, which do not have a load carrying function, to pressure parts. Specifically, I am interested in understanding whether such welding should be exclusively performed by an ASME Certificate...
Hello all,
My company is about to install a pressure vessel at altitude of 8000feet, where the atmospheric pressure is 92.5kPa.
PRV set pressure is 2.8bar(g).
I wonder if the low atmospheric pressure will affect the valve operation.
Hello all,
I have a question about clause 3.4 in NZS 4219, the EARTHQUAKE LOAD DEMAND.
As per equation 3.2, the lateral force coefficient shall be calculated but shall not be greater than 3.6.
The system I am dealing with shall be installed in Palmerston North (Z=0.38 per Table 3), Cp=0.85...
Hello all,
I heard that it is not allowed to use SA-372 Grade E Class 70 for construction of pressure vessels by welding as per ASME VIII-1.
I wanted to know what the exact restrictions are, where are they written and if there is any possibility to use this material in ASME VIII-1 Pressure...
Hello All,
I am trying to understand what would be the best seal (or gasket or soft seat, you name it) material for a safety valve.
Here are the data:
Field of operation: Sterilizers autoclaves.
Fluid: Steam, 2.2-2.4 bar(G) @ Temp ~135°C.
Safety valve set pressure is 2.8 bar(G).
In addition, I...
Hello all,
I have a question regarding the requirement for high-limit pressure control in ASME Section I Power Boiler.
Where does this requirement come from?
What exactly needed?
Any information and reference will be great.
Thank you,

Does the definition of an ASME field site has some distance and\or time limitations?
As per ASME CA-1, "Field Site: the location of final permanent installation of pressure-retaining equipment. All construction activities may be performed at this site."
If the location of the...
Hello all,
According to CA-1, a temporary location is a "location under the control of the Certificate Holder other than the location listed on the Certificate of Authorization, where Code activities are performed."
I would like to know if there are distance limitations for defining a location...
Hi all,
This is kind of theoretical question, but it is something I've been required to do lately.
If you were tasked to qualify welders (not operators) and welding procedures for both EN 9606 and ASME SECTION IX,
Which test piece will you choose for the WPQ and for the PQR? consider the...
Hello All,
I have some disagreements with the A.I with Code related issues (I can give more details if needed)
The thing is, I think that something needs to be done in one way and the A.I disagree.
I gave him a lot of interpretation and quotes from the Code showing I am right.
But he keeps...
Hello All,
I have few questions regarding Fillet Weld Procedure Qualification.
Per Figure QW-462.4(d), the Max. fillet size shall be equal to T - which is the Pipe wall thickness.
1. Does the "Max. fillet size" refer to the weld leg or throat?
2. In order to qualify the procedure, are the...
As of 1 January 2023, all pressure equipment for sale in the UK must be UKCA marked.
I work in a company which manufactured pressure vessel with ASME U stamp and CE mark.
We now facing this UKCA issue and I have some question regarding that issue, and I wonder may be some of you might have the...
