Prevenzione delle sollecitazioni di trazione

Prevention of tensile stressing

Evitare il disallineamento delle tubazioni - 

Pipe misalignment:

Installazione dei prodotti o loro rimontaggio post-manutenzione:

Installing products or re-assembling after maintenance:

Evitare l’eccessivo serraggio.

Utilizzare le coppie di serraggio 

raccomandate.

Do not over tighten.

Use correct torque figures.

Per garantire l’uniformità del carico e dell'allineamento, 

i  bulloni delle flange devono essere serrati in modo 

graduale e in sequenza, come indicato in figura.

Flange bolts should be gradually tightened across 

diameters to ensure even load and alignment.
