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.
The UKB® LS comprises a customisable housing, a reverse acting rupture disc and a three-section knife. This design provides the lowest possible burst pressures while at the same time offering good vacuum resistance even up to high vacuum conditions. The rupture disc and housing are micro-welded and all elements are made of metal. This ensures maximum leak-tightness. Leakage rates of up to 10-10 are possible.
With a wide array of available connections, we supply the ideal pressure relief unit for every application – even for ultra-clean processes. Despite its individuality, a number of “standard” sizes have become established for UKB LS over the last few decades. These are for installation between industry standard flanges.
When the defined burst pressure is reached, the rupture disc is pressed against the knife and opens.
Like UKB LS, plug type rupture discs consist of more than just the rupture disc itself – the housing is also part of the product and can be adapted to an extremely wide range of connections and geometries. Above all, plug type rupture discs are used to protect applications with high pressures and connections with small nominal widths.
By modifying the design of our existing rupture discs, we have made a crucial improvement: Unlike other high pressure rupture discs, the weld seam is not subjected to shear and bending forces – only to pressure. Anyone with a technical knowledge of this area understands that this makes a major difference. Geometrically separating the area under peak stress and the weld seam makes the rupture disc more durable and able to comply with the tightest burst tolerances – tolerances of +/- 3 % and better, depending on the specified burst pressure.
The HPRD rupture discs provide long-term protection for processes with temperatures up to 400 °C and pressures up to 5000 barg and beyond. They have already proved themselves under real process conditions and in a wide range of customer applications. These include reactors, autoclaves and compressors in a variety of high pressure processes, such as LDPE production.
Extruder rupture discs are a reliable solution for relieving excessive pressure in plastic and food extruders. Like all our customised rupture discs, the length, geometry, (threaded) connections, temperature resistance and response pressure can be tailored to your specific requirements. The rupture disc is welded or soldered into the housing. The special gas-tight soldered or welded rupture disc membrane is installed directly in the area of the extruder screw. This eliminates the risk of dead spaces where residues can accumulate.
REMBE® extruder rupture discs can also be fitted with an integrated signalling device (optional), which informs the process control system about the response of the rupture disc. All standard connections/bores for pressure transducers or probes on plastic extruders can be fitted with REMBE® rupture discs.
