DSB123,
The value will be k=1 (The default value). And my sentence about CAEPIPE and CAESARII was wrote only to describe the type of software that is CAEPIPE, less famous that CAESARII ;-)
Hello,
I have calculated a branch SIF by FEA because the configuration branch dosn't exist in B31.3 table. And I wondered what about the coefficient k (Flexibility)? Should I leave CAEPIPE (Equal to CAESAR) calculate in accordance with B31.3 or should I re-determined manually or by FEA...
Hello,
I want to know if somebody has API to calculate the following stress in plane element:
- Primary General membrane stress (Pm)
- Primary bending stress (Pb)
- Secondary membrane plus bending stress (Q)
Because several results exist and I don't know which to use for the analysis of the...
Thank you john.
I confirm the allowable stress in expansion. The material is pipe 304L with:
Allowable sustained: 172 MPa
Allowable expansion: 258 MPa
Allowable liberal: 295 to 400 MPa according to the pipe way and his supports.
I will read your answers and will study them and return towards...
Ok but the allowable stress in expansion is 295 MPa and the yield strength is 175 MPa. The maximum calculated stress in pipe at -140°C is 240 MPa > 175 MPa.
That means that the pipe is deformed in the plastic range (But the stresses are allowable according to the code) and consequently the...
Hello,
My question is the next:
If I have two temperature conditions in my pipe (T1=-140°C and T2=50°C). Must I calculate the expansion stresses by making T1-T2 or just T1 and T2 in two different case ?
Thanks
