Forward acting rupture disc

Bursting discs are pressure relief devices protecting a vessel or a system from damaging high or low pressure by making a disposable membrane burst. Bursting discs consequently act as a type of predetermined breaking point. STRIKO process technology disposes of a comprehensive range of bursting discs and differentiates for instance between forward acting and reverse acting rupture discs. STRIKO forward acting rupture discs are aligned with the concave side to the process medium, i.e. the bulge of the bursting disc points away from the process. If the process pressure exceeds the permitted operating pressure the tensile strength of the material is reached; the disc bursts. In the production of forward acting rupture discs, STRIKO process technology also uses ultra-modern, laser-based production technology. Forward acting rupture discs made of metal of the STRIKO series SZ-X are installed in the standard holder SHZ or in the pre-loaded holder SHZ Pro between flanges. They are particularly suitable for safeguarding medium to high working pressures, can be used as sole pressure safety protection or in combination with a safety valve, dispose of a fragment-free opening behaviour, are suitable for gases, steams and liquids and are available in various materials such as high-grade steels, nickels and special materials such as Hastelloy® or Tantal. Alongside a multitude of design options the forward acting rupture discs made by STRIKO can also be combined with an optional burst indicator installed on the discharge side.
