The max. permissible pressure levels for shipbuilding and industrial applications are stated on the pipe coupling's label.
3. EPDM
For water, air and solids.
4.
If there is a risk of corrosion, use bolts and bars made from
stainless steel (CrNi). To protect couplings in the long-term,
use shrink sleeves or protection tapes.
5. DISTANCE BETWEEN PIPE ENDS

The specified tolerances must not be exceeded or combined. They refer to static loads and radially rigid pipes.
A safety factor has to be included for dynamic loads such as pressure surges, external forces, etc.
