Good evening! Greetings from central California. I am brand new here, so thanks very much for admitting me to the forum. I see some familiar names on the forum here from other places around the web. Hopefully I'll be able to contribute from time to time without embarrassing myself...

In the meantime, I have a question. I am confused as to how to properly handle the longitudinal weld seam joint efficiency in CAESAR. I have a model with 42" spiral-welded pipe, made from 0.394" A36 plate. The B31.3 joint efficiency for this pipe is E=0.85 from Table 302.3.4. Also, no efficiency is listed for this material in Table A.1B.

Where do I input the 0.85 in the spreadsheet? The online Help tells me NOT to input a value for E in the Eff box. Also, do I need to check the Seam Welded check box, or not?

Thanks guys!
