Overpressure and vacuum is feature of virtually every production process. If the pressure rises above or falls below the specified limits, major damage to plant components may result. The consequences are production standstills and serious commercial losses. A reliable and fast reacting pressure relief system is therefore essential to protect the plant in case the pressure rises above or falls below these limits.
REMBE® rupture discs are high precision safety devices that incorporate state-of-the-art technology. They are individually manufactured and tested for every application. When the pressure reaches a pre-defined limit the rupture disc opens to relieve the system. Our rupture discs can be used as either a primary or secondary relief devices. They can also be used in combination with safety valves. The advantage here is that the valve is protected against contamination by the product or corrosion damage. This is often an attractive and cost-effective option.
Contact us – we will be happy to advise you about the most suitable rupture discs for your process. Individually, in detail and taking all relevant parameters into account.
Instant response: nothing reacts faster than a rupture disc. Excessive overpressure and vacuum is relieved in milliseconds.
Full bore opening available for pressure relief: the entire cross-section is used for fast and safe pressure relief.
Leak-tight: prevents process media from escaping during normal operation and thus reduces the costs and problems associated with such losses.
Economic solution: significant cost savings compared to other safety systems for pressure relief
All REMBE® rupture discs are Made in Germany and certified in accordance with the Pressure Equipment Directive (PED – 2014/68/EU) as well as all widely recognised and sector-specific international regulations and standards. Among others, these include ASME Sec. VIII, Div. 1, KOSHA (South Korea).
Maximum reliability at high standard operating pressure ratios.
Reverse acting rupture discs are installed with the domed side of the rupture disc facing the process. In this configuration, the rupture disc offers a higher standard operating ratio and better vacuum resistance. It is more resistant, more rugged and gives a longer service life. A higher standard operating ratio allows you to operate your system under a higher load without the risk of fatigue or premature opening of the rupture disc. Since REMBE®rupture discs have an exceptionally long service life, they minimise the risk of commercial losses caused by production downtime. A specially developed production process using lasers guarantees that REMBE® rupture discs offer maximum reliability, precision and manufacturing repeatability.
In forward acting rupture discs, the domed side of the disc faces away from the process. At REMBE® we also use state-of-the-art laser production techniques when manufacturing forward acting rupture discs. With a wide choice of materials and designs, we can supply the perfect rupture disc for every application – customised for your process.
Flat rupture discs from REMBE® offer you fragmentation- free opening across the full width of the vent. They can be produced in virtually any size, for extremely low pressures from 15 mbar and with very low burst tolerances. For protection against overpressure and vacuum, e.g. in storage vessels and low pressure systems. Also suitable as a secondary safety device alongside breather valves. This rupture disc is designed to work at standard operating ratios of up to 50 %* of the min. response pressure. It is installed directly between flanges and due to its half holes is suitable for all flange systems. A wide range of materials can be used as seals. * Depending on the specific application.
Very high or low pressures, high vacuums, temperatures of several hundred degrees Celsius, highly volatile media or difficult installation situations – if your processes have exceptionally high pressure relief requirements, you will find the optimum solution in the following section. We have even successfully protected space satellites against overpressure. As you can see, no application is so lofty that we cannot protect it with the appropriate rupture disc. With more than 1000 different starting materials, we provide you with fast and reliable pressure protection. In our warehouse there are, among other things, stainless steels of the highest purity, e.g. 1.4435 or 1.4404, nickel, monel, inconel, hastelloy, tantalum, titanium, zirconium as well as various precious metals and high-performance plastics. Possible connections: CF / KF flange, ISO-K / ISO-F flange, VCR screw connection, welding neck flange (also with tongue and groove), cutting ring connection, threaded connection.
Extremely corrosive media, low pressures and high temperatures.
REMBE® graphite rupture discs offer you the familiar REMBE® quality and reliability – even in extremely corrosive media, low pressures and high temperatures. The maximum working pressure is 80 % * of the minimum burst pressure. REMBE® graphite rupture discs are applicable for highest temperatures by using a unique chemical vapour deposition method (PyC coating). The rupture discs are applicable from -180 °C up to +500 °C under oxidizing and reducing atmosphere, +1,500 °C under inert conditions. * Depending on the specific application.
Rupture Disc Holder for the perfect Installation and performance for your rupture disc. The various REMBE® rupture disc holders are specially designed to make it impossible to install the corresponding rupture discs incorrectly. Signalling devices for the optimal adaptation of the rupture disc to your requirements. Automated processes use intelligent signalling systems to keep you informed at all times about the status of your entire plant and any faults that may arise.
