Sealed unit rupture discs for fast and safe installation
Pre-assembled sealed rupture disc units designed to ensure correct installation and reduced handling risk.
Rupture disks in installation-ready sealed units, for easy mounting and simplified maintenance
There are some peculiar installation conditions – for example for very small discs, in tiny spaces – where blocking the burst disc in place inside its holder may be complex for anyone who’s not a specialized technician, leading to possible disc malfunction following from an incorrect assembly – with the consequences upon the safety of the operators and the plant itself which can easily be imagined.
DonadonSDD solves this issue with a range of pre-sealed units: rupture discs welded upon the connector, or inserted in special sealed, threaded containers, ready to be easily installed even in the most critical positions with no need for specific competence.
