Pressure Vessel Analysis and Design 1

[RANMAN3]

I don't have any money and am learning PV analysis and design to get into the industry. Does anyone have or know where I can get ASME or Euro codes to learn design criteria; materials, stress, etc. I have a PV designer in Autodesk multiphysics and I want to design at the margin under a specific pressure, diameter, wall thickness, and elliptical head. I'm using max shear stress failure criteria and room temperature right now. Somewhere to calibrate my analysis would be great. Can someone help with some basics?

Thank-you

You're new here, so I'm going to cut you a little bit of slack.

The ASME and EN Codes are not free, and if you ever ask for them for free here you will be kicked out. They are copyrighted material, and to ask for them to be given to you for free is highly unethical.

Why do you want to get into this industry? How do you expect to do that if you aren't willing to "put a little skin in the game"? What do you think that you can offer competing against other engineers that have been doing this their entire careers?

If you have the expectation of performing Design-By-Analysis, and you are doing so for a company that is located in a jurisdiction that requires one of the various Codes, then you must follow that Code. You can't go and do your own thing - technically that would be considered illegal in those jurisdictions. In North America, that Code is the ASME Boiler and Pressure Code. For Design-By-Analysis, you would need ASME Section VIII, Division 2, Part 5. To say that the learning curve for that is steep is an understatement. Many of us have been using (and involved in writing) it for 15+ years and we're still learning. Having a computer and some software is only a recipe for disaster.

Oh - and you may need to make sure that, if you are practicing engineering in a jurisdiction that requires it, you may need to be registered as Professional Engineer, too.

You also want to "calibrate" your analyses. That's good. Start with papers written in the last 15 years at the ASME PVP Conference and ASME Journal of Pressure Vessel Technology. Again, not free - so don't expect it to be so. Search the archives here on eng-tips, too.

I don't think that RANMAN3 was asking to violate copyright law. I do know that some university libraries have copies of the ASME code books, and they may permit you to use them for research purposes, but you cannot copy them or check them out.

You may also have some success reading the following text. While it does not contain enough information to design a vessel, it may help you in understanding the process.

TGS4 gives some great advice to consider before jumping in to engineering consultancy and pressure vessel design. Definitely heed his advice.
