This firm has added new high performance models to its range of rupture discs. For protection of medium- and high-pressure equipment, the rupture discs model SCD (forward acting) and SCR (compression) have a micro-scored calibrated section with six sectors (instead of four commonly used). This allows a better opening and reduces the risk of petal detachment even at very high bursting pressure. For protection of tanks, reservoirs, silos, and other low-pressure equipment the firm has developed the rupture disc model LPD, a simple, reliable, accurate, and cost-effective solution. Even very low-pressure equipment, such as biogas-plant digesters, can be protected from an overpressure of 5–10 mbar. Also implosion (vacuum) protection is achieved in a very effective way. For detecting rupture of such low-pressure discs, the manufacturer has developed an optical rupture indicator (OFI 04). — Donadon Corbetta, Milan, Italy
