Compressed Gas Cylinder Standard for Physical Dimensions?

Compressed Gas Cylinder Standard for Physical Dimensions?

(OP)
We would like to specify a standard cylinder size for use on the project so we can design our racks for the cylinders and not be tied down to any specific supplier. Note the racks will be designed before the gas supplier is selected.

At first glance it looked like the Department of Transportation (DOT) Specification is the industry standard for cylinder size. Specifically DOT 3AA-2400, where 2400 is the cylinder pressure (psig).

A survey of multiple suppliers shows that the cylinders of the same DOT specification have close to the same dimensions (+/- 0.25 in) (LINK, LINK).

After reviewing the DOT specification, it appears the DOT spec. covers fabrication and not the physical dimensions of the cylinder (LINK).

It appears the various suppliers provide the same product physical dimensions, but there isn’t actually a governing standard for the physical dimensions.

Does anyone know of an industry standard that covers physical dimensions of compressed gas cylinders?

RE: Compressed Gas Cylinder Standard for Physical Dimensions?

If you search the various Compressed Gas Association standards I think you'll find that the size of compressed or liquefied compressed gas is constant.

Conversely, cylinder valves, their threads and means of pressure means is material specific.
