Screwed and bonded disc and plug
unit for safety critical applications
Our O4A component combines a brass body as standard with either a stainless steel or nickel disc, depending on burst pressure and process requirements.
The conventional, forward-acting rupture disc is clamped between an inlet and an outlet which are then screwed and bonded together. This provides a robust unit ideal for safety critical applications such as gas handling or cryogenic applications.
We typically use thread-lock or an equivalent material to prevent tampering, and offer the unit with a range of thread connections and combinations to suit varying specifications.
O4A is available our innovative burst detection system, OE-Tel. OE-Tel is the first ATEX-approved detection system for OEM rupture disc components. With a fail-safe design, it is not affected by downstream pressure fluctuations or corrosion.
