Widest range of Electron Beam Welded Rupture Disc Solutions
The OE6 rupture disc is a scored forward or reverse rupture disc that is Electron Beam Welded in between the inlet and outlet sections of the plug. The use of electron beam welding ensures the highest integrity joint possible, ensuring that leakage is not a problem for applications where it is essential that the process medium is not vented into the atmosphere.
Typically manufactured as a stainless steel body with a stainless steel or nickel disc, available with the widest range of inlet and outlet configurations.
OE6 assembly is a superior performance solution for demanding applications
The high integrity OE6 rupture disc design is able to cope with extremely low temperatures and high pressures for superior performance in a range of applications. The disc is suitable for various environments such as oil and gas, pharmaceutical, aerospace and many others.
The OE6 rupture disc design gives exceptional leak tightness up to 10-8 cc/sec and outstanding operational performance. The optional baffle outlets provide controlled venting, suitable for those harsh operating environments.
OE6 rupture disc assemblies require zero maintenance once installed.
