For a 16 ", seamless ASTM A53 steel tube Schedule 160 Inside diam 14", used as a Fluid (oil) power cylinder What it is the max allowed pressure? Please take in notice it is a non to be practical use. I WILL NOT BUILD IT. I used this calculator http://www.engineersedge.com/calculators/shell_internal_pres_pop.htm But it give me a so thin wall. See scree shot from the calculator. Thank in advance

The calculator results looks suspect - I'll get it reviewed ASAP! Thanks for the alert!

Ok, I see the problem. The (E) Joint Efficiency data should be entered as a decimal. 100% = 1.00 or 80% = 0.8. This realy should be changed within the calculator (on the list).
