Dear all,
While i'm performing WRC 297 in caesar, i am getting an error "More than one NON-ZERO LENGTH element ATTACHED to the nozzle".
Please suggest a possible solution for this.
Thanks in advance.
Dear friends,
Recently, in a revamp project , the client asked me to provide him the bolt torque values. As per my understanding, bolt torque values or chart is project secific and client has to provide us the same for compliance ryt?
Or is there any code/standard where in i can check for the...
Dear all,
Please help me as am a fresher in stress analysis…
When we do nozzle load check in CAESAR II for a nozzle oriented in 30 deg or 45 deg horizontally, should we rotate the whole system and align the nozzle with any axis and then check the nozzle load ?
thanks in advance

First of all, you cannot choose a pipe to withstand sustained load and occ. load.
You have to design your pipe based on its process parameters and design basis and fix it.
Then you stress analyse the system to make it good enough to withstand sus. Load and occ load.
Maximum...
Friends,
I have an 8"-Sch80 - A106.B / BFW / 900# line .
The design Pressure for this line = 114 Kg/Cm2 G
The hydrotest pressure (as per spec.) = 171 Kg/Cm2 G
But,from ASME B16.5 flange rating table, maximum pressure for class 900 is 147.75 @ amb temp(60deg c).
So,is this hydrotest pressure @...
What I could infer from the above posts is that add a margin to operating temp and pressure. Say 20% and that will be the design parameter.
But earlier in a forum I read that, based on the fluid category , the margin varies. For ex.
Category D = 1.1, 1.2 max
Category M = 1.4 to 1.6 etc…...
gjmorin "Then a condition assessment (UT, RT, etc) as indicated above would be appropriate to check to see if the installed line can handle the pressure"
How to do this conditional assessment with UT, RT etc ?
Dear dcasto,
Thank you for your reply.
Let me clarify what u stated ..
Suppose the Existing Matrl. spec = A106 GrB
Operating Temp = 150 Deg C
Thickness = Sch 40
So, u mean to say you will find "P".
Now that P = design pressure and " 20% over the normal operating temperature" = Design...
Hello friends,
Myself is a beginner in stress analysis.
I have a doubt.
In most cases i happen to work for very OLD Plant expansion projects.
The input from client will be certain OLD existing documents. Most cases from scratch.
Suppose i have a line list that show only Operating pressure and...
