L/D RATIO OF HORIZONTAL Pressure Vessel
L/D RATIO OF HORIZONTAL Pressure Vessel
(OP)
Is there any limitation on the maximum l/d ratio that can be used for a hozl. vessel?
I want to use only two saddle supports.
thanks for your help

You may want to go to CODEWARE, The Home of COMPRESS for the L.P. ZICK PAPER:

You want to consider midspan deflection as well as the "aesthtics" of the installation. The maximum stress levels in the Zick design guidline is not the only criteria you should use.
Saddle deflection plays a role here too. Too much rotation can pry anchor bolts
The propane tank people have probably pushed the l/d thing to it's limits (longer tanks are cheaper on a cost/unit volume basis). I believe that they have gone to about 10 or 12:1........See this link

Also, contact the people at "hanson tank"....they are very helpful

As a coutesy, please let us know how you make out.......we are interested in learning too.........

The deflections and rotations of the cylinder can be estimated using the usual beam formulae.
I have found that CodeCalc and PVElite accomplish the analysis comprehensively.
