ERD Series Extruder Rupture Disc

The Fike Extruder Rupture Disc (ERD) is a pressure relief device primarily designed for overpressure protection of plastic extrusion processes.

Each ERD device typically consists of a threaded tubular body with a rupture disc soldered or welded to the process end.

It is necessary that the rupture disc of an extruder pressure relieving device be mounted flush with the inner wall of the extruder barrel.

Another configuration, or improperly designed device, would present a pocket area for product build-up and hardening that could render the device totally ineffective.
