High-performance electron-beam

welded disc and plug assembly

The OE6 rupture disc assembly combines a scored forward or reverse rupture disc that is electron-beam welded between the inlet and outlet sections of a plug.

This high-performance component can withstand extremely high and low temperatures and offers a full vacuum service.

The optional baffle outlets provide controlled venting, making the unit particularly suitable for harsh operating environments.

Typically manufactured as a stainless-steel body with a stainless steel or nickel disc, OE6 is available with a wide range of inlet and outlet configurations for full customisation.
