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.

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.
(Contact manufacturer for further information.)
11. THE FOLLOWING INFORMATION (11-15) MUST BE OBSERVED! 
Remove burrs and clean pipe ends. Damage such as scratches, cracks, etc., or coatings such as paint, rust, etc., must be
removed from the sealing lip area.
