Tank Nozzle Load Calculations 1

[merton]

Does anyone have an Excel sheet or know of similar resources that could assist in calculating nozzle loads for API 650 tanks?

Thanks in advance.

Appendix P offers some assistance, though it currently has constraints based upon tank size. WRC 107 is commonly used. It is cumbersome to do by hand. There may be commercial software (such as Coade) that can do the calcs for you.

Check out the alternate design approach in the latest App. P, which is not that cumbersome, and much simpler than WRC 297, on which it is based.

I wrote a pretty slick excel spreadsheet that designs the nozzles per the alternate design approach from appendix P. Download it from

If you want to see the tables and equations that are included in the spreadsheet, unhide the rows at the bottom of the spreadsheet.

Please post with any questions.

Hi, I'm trying to use the alternative procedure of the appendix P for nozzle loads, but I don't understand clearly the difference between "t" and "T". According to the API 650 appendix P, "t" means: "Thickness of tank shell at location of nozzle" and "T" means "Thickness of the tank shell at the opening in question". I think that "t" means the nozzle thickness, but in the same page describe "tn" like the nozzle thickness. I'm really want somebody explains me the meaning of those terms. Thank you.
