standards per idroule cylinder

[AngeloB]

Hello everyone
what are the most useful standards for designing and "normalizing" a hydraulic cylinder and a pressure vessel? even if they are no longer in effect is the same. I, for example, prefer to use the one 10011 for the verification of the structures, to the most recent norms I have not yet got used to

Thank you.

the fact is that 10011 is still used even if, since there are now Eurocodes and the rules that depend on them, it would be better to adapt to the state of art.
the pressure vessels fall within the ped, so you have to look at the harmonized standards under the ped directive.
for cylinders I think there are dedicated rules (something with the cetop theme is something).
if you have to check a cylinder, use eulero for the tip load and the formulas contained within the ped standards for the containers.
I do this!

hi gerod,

only a clarification regarding ped (97/23/ce), as I remember that under some pressure it is not obligatory... (if not up to 0.49bar)

of course depends on the field of application.
the company for which I work has produced them for decades for the naval field and in that within every register of certification refers to its own regulations, that for this matter of refer to norms, in general, used in the country of the register itself - example: the a.b.s. (american bureau of shipping) it refaces to the code a.s.t.m. (American society for testing and materials).
However both following the standards of good design and choosing rather high safety coefficients (from 7 up) you should have no problem.
