Dear All,
In one of our projects, we have to consider the blast/drag load in vessel design. Client specification says vessel should withstand drag forces of 0.4barg with a time span of 200 milliseconds. I’m thinking to consider this drag pressure same as a kind of wind pressure and apply on the...
Dear All,
According to ASME Div 2 (5.3.2)for the elastic stress analysis method summation of the principal stresses must be lower than 4S. From a CAESAR model there are two different type of loads, operating and sustain. If i want to calculate the principal stresses by a software (e.g nozzle...
Hi All,
We have to design a vessel at high temp. 700C according to DIV2, the result of P-elite shows that two nozzles are close to each other and there is interference between them, even the available area is higher than the required. we make a FEA for these two nozzles and the stresses based...
Dear all,
Our client asked us to perform creep analysis according ASME VIII Div2 for a reactor with DT=700C and DP=5barg material is SS 304 (all. Stress = 25Mpa). Please let me know if we must check the creep for the reactor or only for the nozzles. Can we perform finite element (e.g by FE Pipe...
TGS4,
In the client specification, it is mentioned "Pressure vessels which operate in creep range of the materials of construction shall be designed acc. to Div2"! is it referred in Div2 that design into the creep regime is not allowed?
Dear All,
Regarding high design temperature(~600C)and SS304H as material our client ask us to design a reactor according to ASME VIII Div 2 and performing creep analysis. Acc. to SecII-D max. applicable temp. based on Div 2 for SS304H is 800F(~427C)and there is no allowable stress for 600C. For...
