Assuming the larger and smaller flanges are standard sizes, a standard Reducing Flange (250 DN/10" to 80 DN/3" or similar) is a often simple but robust solution. The only weld required then would be two circular seams for pipe to reducing flange and pipe to smaller flange. Similar to below...

We have the unwelded material and have not begun working on the vessel. What do you mean by "you can quench and temper the 410 material to a specific strength level."? Also,where does the code say this is allowable? I apologize for the elementary questions regarding this process; it is not...

My company has a request from our customer to quench and temper a small vessel made of 410SS. They would like to do this to be able to take credit for better material properties to be used in ASME Code calculations. I believe there is a section of the code that deals with being able to use...

Thanks for the replies. I did find this type of design in the Bednar PV Design Handbook. It's a relatively straight forward calculation concerning how to check the basering thickness and weld sizing required. Thanks Doct9960! To check for buckling between the openings above the pipe, would an...

All, My companies customer has requested that we evaluate the attached basering design. A pipe is welded along the bolt circle and integral with the skirt. A hole is cut above the skirt to allow the nut to be placed and tightened on the stud. The vessel is rather tall and located in an area...

I'm trying to check for the acceptability of transportation loads on a horizontal vessel and the customer has provided G-Loading values in the longitudinal, Transverse, and vertical directions. Can this be accomplished in Compress? I do not see an option for custom loadings like this. Thanks.

I have been requested to analyze the design of a clip that is situated at the intersection of the top of a stiffening ring and the vessel. Please see attached image. WRC-537 is too conservative in this case and fails since no support from the ring is taken into account; however, I do not want to...

I am modeling a section of a pressure vessel in SolidWorks to check a ring with internal head assembly by FEA. The design temperature is at 1050 degrees F. I need the yield and tensile strengths for SA-387-22 Cl. 1 for this vessel or even all the various mechanical properties at various ranges...
