Hallo guys,
i observed that a smaller expanded length leads to an increased tubesheet thickness.
This is not fully plausible to me...
Now my question is where do i find this in UHX 12 of ASME VIII division 1
Im looking for that equation but i couldnd find something in this chapter
Can...
Hallo,
can anyone explain me how the 75 ksi max allowable bolt stress been calculated or how it is derived?
I do know the 172 allowable form ASME II Part D but dont understand the 75 ksi in the table
Thank you BR Stefan
Hallo guys,
i do have a question i have a flange calculation where i do exceed the limit for g1
i do have g1>5xg0 therefore the calculation uses 5xg0 as a maximum value in the calculation.
But i cannot find this in the ASME Division 1 Appendix 2 Chapter.
Can anyone help me where i do find...
Hallo guys,
i was asked why i do limit the allowable stress while test pressure to 90 % of yield stress at test temperature.
Now i know that it is common praxis to use 90 % as additional safety factor. But is there a clause in the Norm anywhere so i can add this link?
I cant find this 90 %...
Hallo guys,
i need to perform a calculation to show what is the maximum allowable test pressure without exceeding material minimum yield strength.
According ASME B31.3 How should i perform this.
eventuelle refomring an equation?
Thanks lg Stefan
Hallo,
i have a understanding problem and i hope you guys can help me.
While calculating the maximum occuring displacement Stress (analytical).
according code the Thermal Force is calculated in uncorroded condition using nominal wallthicknesses.
In Detail:
The Area for stresscalculation is...
Hallo guys,
i need to perform a calculation report for ASME U Stamp Audit.
The Pressure vessel should be 650 bar / 260°C and ASME Division 2
The material is SA723 Gr3 Cl3
Now my problem is that i cant find allowable stress values for that special material.
Im looking in the ASME II PART D...
Hallo guys,
i have a code issue problem and would need your help.
This material has a ultimate tensile strength of 490 [MPa] @ 20°C and a yield strength of 355 [MPa] @ 20°C.
Now for the allowable stress according B31.3 2016 does chapter 302.3.2 (d)(1),(2) apply or 302.3.2 (f)?
What is the...
Hallo all,
i have a question regarding this Norm.
I need to verify a nozzle with 67 % Thermal Load and 33 percent dead load of the required forces and moments.
I have internal corrosion and external corrosion and a design pressure of " P "
Why does the WRC Bulletin 537 not taking the design...
Hallo guys,
im new to ASME and i have a question:
I need to calculate a normal pipe. But im not sure how to add the corrosion and mill tolerance to the equation correctly:
I have that 2 equations:
R .... inner radius (nominal)
Ra ... outer radius (nominal)
c1 corrosion
c2 mill tol.
t0 ...
