FSKRDN - NanoScored Rupture Discs
The FSKRDN NanoScored rupture disc incorporates advanced technology to deliver highly reliable overpressure protection. The convex disc maintains its original shape during normal operation and only reverses at the set burst pressure. It supports operating-to-burst pressure ratios of up to 95% and withstands thousands of pressure cycles without loss of performance. When activated, the disc opens fully in milliseconds along the scored line, producing no fragments. Compared with conventional designs, it is less sensitive to temperature fluctuations, making it ideal for applications with wide temperature variations.
Thanks to its innovative construction, the FSKRDN can operate with liquids only, including in cycling and pulsating conditions, without compromising safety margins. It is particularly well suited for isolating safety relief valves. A wide selection of materials and optimized thickness provide excellent corrosion resistance, which can be further enhanced with an optional PTFE lining on the process side. The disc does not require vacuum support and is capable of withstanding high back pressures.
