Striko – SZ Foward Acting Metal Rupture DiscEnquire Now
Striko SZ forward acting metal rupture discs (bursting discs) are high precision safety devices for overpressure protection that are installed in a standard holder SHZ or in a pre-torqued holder SHZ Pro between flanges. When the process pressure reaches the pre-defined limit, the disc opens to relieve the system keeping personal and plant safe.
Striko SZ series can be used as a primary or secondary relief device and can also be used in combination with a safety valve. They are ideal for pulsating working pressures of medium to high strength.
Protect your Safety Valves
When using the Striko SZ rupture disc before a safety valve, you
- Can use a safety valve with standard lower cost materials in a corrosive application.
- Reduce fugitive emissions past the safety valve, due to the rupture disc being leak-tight.
- Reduce the costs of maintenance extending the life of the safety valve.
- Stop viscous media from adhering to and blocking the safety valve, hindering its performance.
SZ-X series is a convex domed cross-scored rupture disc that fulfills the highest requirement of tightness. The SZ-X is ideally suited for processes with medium to high pressures as well as volatile media where it protects your process reliably. Due to its non-fragmenting bursting, it can be easily installed in combination with a safety valve. It’s “Fail-Safe” design ensures that should it be installed incorrectly, it will fail at or below the specified burst pressure. They are installed in Striko SHZ and SHZ Pro holders.
SZ-M series are composite discs that are domed. Individually designed for your application they can have low and high burst pressures. Most commonly, these rupture discs are used for processes with pulsating pressures on processes with gases, liquids or multiphase media. They can be installed directly between flange connections or in Striko SHZ and SHZ Pro holders. For larger diameter sizes they can be installed directly between flanges.
SZ-MV series is a SZ-M with integrated vacuum support for full vacuum or high back pressures.
