Hi All,
I need to know that the maximum size of branch nozzle that can be drilled on a run pipe as per ASME B31.1.
I found that the maximum size of hole on vessel as per ASME Sec 1 (PG-32.1.2) & ASME Sec VIII Div 1 (UG-36 & Mandatory App 1.7, 1.9 & 1.10).
I am new to B31.1. Even I found for...
Hi All,
As per PV Elite attachment, Allowable stress due to hydrotest will be 90% yield or as per (asme sec viii div 1) 1.3 times of ambient allowable stress. Can anyone tell the exact location of that point on div 1...
HI,
Can anyone please advice me that how are the highlighted values are calculated from top table(Stresses in the vessel at the attachment junction) in attachment? Please refer the attachment. It's a pv elite...
Hi,
While calculating allowable stress value using sec II part D & code of construction is sec Viii Div 1 for SA-240 304 at 150F, it show just "-"(hyphen)only. that symbol refers to what?
Can I use that material at 150F? How can I find the allowable stress value at 150F for that material...
Hi all,
As per UG-27 (c)(1), E stands for joint efficiency or ligament efficiency, whichever is less to be used.
My questions are,
1) While modelling the vessel in PV elite, The software doesnot consider about the ligament efficiency for nozzle holes, why???
2) In asme sec viii div 1, UG-53...
Hi All,
As per WRC 107, I calculated the Induced combined stress intensity in nozzle shell junction. Now, I need the Allowable stress intensity for comparison.
But in PV Elite calculation, the induced combined stress intensity is compared with allowable stress for Div 2 as per table 5A in...
Hi,
In ASME SEC VIII DIV 2, Design Rules for Supports and Attachments, There are two formulas for calculating angle ρ,
ie) ρ = tan ρ[0.5+(∏-ß)cotß].
ρ = -158.58+7.8668θ-8.8037(10)-2θ2+4.3011(10)-4θ3-8.0644(10)-7θ4
Can anyone pls. suggest me which one can I use to calculate ρ for Stress...
