Donadon SDD is proud to announce the new series of rupture discs NS NanoScored

Donadon SDD is proud to announce the new series of rupture discs NS NanoScored; the new contents are available on: www.donadonsdd.com.

The NS NanoScored rupture discs series includes forward acting rupture discs (tension) like Donadon SCD/NS and reverse acting rupture discs (compression) like Donadon SCR/NS (6 or more petals) and Donadon Y90/NS (opening on perimeter).
Rupture discs of NS Nanoscored are fully metallic and adequate for all applications.

Main advantages are:
 Accuracy
 Reliability
 Non fragmenting even at high bursting pressure
 Low bursting pressure (less than 0.5 barg – 7 psig) also for DN 25 (1”)
 Available from DN 10 up to DN 600 (24”)
 Material flexibility
 Model flexibility
 Standard or sanitary (Tri-clamp) holders
 Standard tolerance +/- 5% on full range
 Reduced tolerance according to customer requirements

The new manufacturing technology developed and patented by Donadon SDD allows to manufacture scored rupture discs also with materials of very low thickness (in practice with every thickness industrially available) ensuring high reliability and strict tolerance It is therefore possible to extend the range of bursting pressure to lower bursting pressure than normally available.
