It is my impression that there is a little of confusion between bolt torque, bolt tensioning and elongation.
Flange tightening is performed by bolt torque (i.e. by wrench) or bolt tensioning (i.e. by hydraulic tensioner).
Both methods have some assumption and imprecision for instance the...
I agree that you may use 6.3(d), just drafting half of the symbol.
I'm a bit perplex you are using an "uncommon" weld detail that you even did not know how to indicate, but again, if you are able to qualify it...
Hi,
1. in edition 2023 of code i see a different detail. Note that figures UW-16 are "some acceptable...", not mandatory. Even if i never seen square groove weld, in particular in shell to nozzle joint, any detail as long as it is qualified with a dedicated PQR should be acceptable.
2. google...
As already asked, what is the point on arguing on gr.60 or 70? Without knowing the real problem, we are just blinding answering you.
If certificate says gr.70, formally it is a gr.70.
Then, there is a wide overlapping range between gr.60 and 70. They are almost the "same" material.
Often...
Question is a little vague and probably not pertinent to this forum since it is not "heat transfer" related.
Since it seems you are speaking about shell and tube HE, I suggest you to start reading API 660 and IOGP S-614 recommendation.
Dear FPPE
I do not have now b16.5, but have you verified if bolts b8 cl2 are classified as high or intermediate strength?
If they are classified as intermediate, you shall perform a detailed calculation and from that you can easily obtain a bolt load to be applied. Total load is the wm1 load...
Hi,
I cannot help regarding the metallurgist phenomena.
For an engineering evaluation you may refer to ASME FFS, as stated also on API 510.
For repair activity you may check ASME PCC-2
Hi,
I would not accept a proposal per your sketch.
Typically, flange type, gasket, material are all decisions taken by client.
Generally speaking, what is the internal diameter? Is the shell integral in alloy or CS+CRA? Is really not economical provide an integral flange base on flange...
Dear All,
I am seeking your guidance on table table 5.3 of ASME VIII, Div.2.
On table 5.3 are reported several loads combination in design and operating condition with related allowable stressed.
1 - Self-restraining load T
Recently, I have seen several reports where temperature is neglected...
Dear All,
as per ASME VIII div.2 ed.23, fatigue screening method B has changed.
I am not sure on how to understand certain calculation of the screening.
Let check for instance eq. (5.19).
The damage associated with the full range pressure cycle is the ratio between the number of full pressure...
I think so, but i do not get your point.
It is just my wording not totally correct (i have tried to edit the original post and make it more clear) or i did a trivial mistake?
Dear All,
I am replicating the example problem E5.2.2 and I am facing some issue in the inputs.
I have created my own spreadsheet as per annex 3D and I am comparing my results with the material input data given at E5.2.3.
Why as per E5.2.3 in the tab data elastic strain is considered equal to...
