Description
Burst Plugs (also known as rupture disks) are designed for reliable, emergency relief of excess pressure in a system. The Model BP420 will instantaneously rupture at a specific, predetermined pressure range. (A TechNote is available that describes the effects of process temperature on the effective range of the rupture disk.) The Model BP420 burst plugs are designed specifically for use in plastic extrusion systems. Each assembly consists of a 303 stainless steel body with an Inconel rupture disk. A burst plug may be specified for primary relief in applications where pressure build-up can occur so rapidly that the response time of a relief valve is inadequate, such as in a polymerization reaction vessel.
