Donadon SDD has invested in research & development and in the purchase of new machines with last generation technology. The result of these undertakings is the series NS NanoScored.
These are very precise and reliable discs that can be manufactured in a very broad range of diameters and pressures.
Indeed, the new productive processes developed by Donadon SDD enable to obtain rupture discs that are:
- resistant to fragmentation even for high burst pressures
- with rupture pressures below 0.5 bar (7 psi g) even for DN40
This innovative technology has allowed Donadon SDD to implement new rupture discs entirely made with laser, not available on the market:
- compression loaded with 6 or more radial scores (SCR/NS model)
- compression loaded (reverse buckling) with Perimetral scoring (Y90/NS model)
- tension loaded with 6 or more scores (SCD/NS model)
- for standard or sanitary disc holders (Tri-clamp)
Both the production process and the brand are patented.
