The OsecoElfab FST™ rupture disc is designed and manufactured for high-performance and demanding rupture disc applications.
The FST is scored after the forming of its low crown. This yields a high-performance disc that can withstand the most difficult applications, especially in materials such as tantalum.
The FST rupture disc has an 85% operating ratio for applications requiring a high operating to set pressure ratio.
Due to its high operating ratio and non-fragmenting design, the FST is an excellent choice for isolating safety relief valves. Installing the leak-tight FST disc between the process media and the safety relief valve protects the valve and prevents emissions to the atmosphere.
