Overpressure protection for extrusion processes with industry best lead-times

Elfab provides its customers with the widest range of pressure relief products, from unique one off solutions to high volume assemblies with the best total supply chain costs available in the industry.

The Elfab Extruder Rupture Disc (ERD) is a high performance pressure relief device primarily designed for overpressure protection of the plastic extrusion process. Using our state-of-the-art in-house manufacturing capabilities we will work with our customers to provide a cost-effective solution for this application. The ERD is available in a wide range of configurations with many configurations held as stock components to offer industry best lead-times.

Leak-tight designs for advanced process management

Each of Elfab’s Extruder Rupture Discs consists of a threaded body with a conventional rupture disc welded to the end. This ensures the disc sits flush with the extruders pressure vessel wall, preventing potentially damaging product build-up. Understanding the need for tight process management and leakage control, Elfab manufacture each device using our advance in-house electron beam welding capability. Elfab can supply these devices with leak rates as low as 10-8 cc/sec. As each ERD application is different a combination of dimensions, thread types and body configurations are available.

Widest stock range on the market

Elfab’s extensive stock range is available across a wide range of burst pressures in industry common sizes and thread types. Our stock items are typically available from 46mm (1.81”) to 165mm (6.5”) long with a 5mm nominal bore Inconel rupture disc in a Stainless Steel Body. Our advanced in-house engineering capability also enables us to work with each customer on an individual basis to custom engineer a unique design to meet varying specifications. Elfab manufacture the ERD with a range of head configurations to allow for ease of installation and compatibility with this industrial application.
