FSSCDN - Nanoscored Rupture Discs

FSSCDN - Nanoscored Rupture Discs

The FSSCDN Nanoscored rupture disc features precision micro-scored petals with four, six, or more radial scores, ensuring rapid, controlled opening while minimizing the risk of petal separation. This design makes the disc particularly well suited for high burst pressure applications and demanding operating environments.

Engineered for use with gases and liquids, the FSSCDN performs reliably under cycling and pulsating conditions without compromising safety margins. In the event of overpressure, the disc activates within milliseconds and opens cleanly without fragmentation, making it an excellent solution for protecting safety relief valves.

The disc supports an operating-to-burst pressure ratio of up to 85% and offers excellent corrosion resistance, which can be further enhanced with an optional PTFE lining. In many installations, the disc can also withstand full vacuum conditions without the need for additional supports, providing greater installation flexibility.
