Rupture Plugs and Pressure Transducers

Rupture Plugs for Extrusion Applications
Rupture plugs are designed for reliable emergency relief of excess pressure since they instantaneously rupture at a specific predetermined pressure range. Dynisco’s model BP420 rupture plug is designed specifically for use in plastic extruders. Each assembly consists of a stainless steel body and rupture disk. A rupture plug may be specified for primary relief in applications where pressure buildup can occur so rapidly that the response time of a relief valve is inadequate, such as in a polymerization reaction vessel.
