Temperatures and Pressures changing on multiple, unrelated points.
I am updating the temperatures and pressures throughout the model and found that some points on other segments are also being changed. For example, when changing a singular point, K04, to T1=700F, it is also changing points AR00 to AR02 to 700F as well…
Strain Equation

Hi
When AutoPIPE calculates the longitudinal strain due to pressure only (unrestrained system), does it use the equation given below:
dL = (1/E)*(Sl-vSh-vSr)
where:
dL = Change in Length E = Elastic Modulus v = Poisson…
RE: axial stress/axial force don't apeear to be in agreement
rkp,
You were right when you said you may be missing something. The longitudinal pressure stress calculations take in to account the axial force generated due to pressure extension and the longitudinal pressure force or end cap force. Pressure extension…

RE: Correct model of expansion joint
Hello Dudiw,
The only way to be sure which option to choose is to contact the Manufacture who published the catalog and ask them to define "Effective Area". Then see if it matched the definition provide in AutoPIPE's online help for Pressure Trust Area…
