Holder (inlet and outlet part)

The use of bursting discs in bursting disc holders ensures the reliable functioning of the bursting discs. In the holder, the metallic sealing gasket between the bursting disc and the holder inlet part is established – either by using the screws of the flange connection (standard holder) or by the four high-strength screws integrated into the pre-loaded holder. The holders are usually designed in common high-grade steels like 1.4571 or in special materials like Hastelloy®. For graphite bursting discs, holders made of graphite, special materials or even stainless steel with PTFE-coating are used.
