Bursting discs

Rupture discs are non-reclosing safety devices with precisely defined breaking points. They respond very quickly to pressure and can be used to implement pressure relief in many different applications. They protect plants, people, the environment and machinery against the dangers resulting from excessive overpressure or vacuum within a process. Rupture discs were originally a very simple solution. However, over recent years, designs have advanced significantly to accommodate changing system requirements, such as pressure cycling, higher process temperatures and the increasing role played by technology in many industrial processes. The greatest advantage of rupture discs over electronic and pneumatically operated safety systems is their reliability – this makes them one of the most important fail-safe safety devices in industrial operations.

Reverse acting rupture discs

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 in your rupture disc. Since REMBER 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 REMBER rupture discs offer maximum reliability, precision and manufacturing repeatability.

Types of reverse acting rupture discs:
  • KUB
  • KUB-V
  • KUB-F
  • IKB
  • UKB-LS

Forward acting rupture discs:

In forward acting rupture discs, the domed side of the disc faces away from the process. At REMBER 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.

Types of forward acting rupture discs:
  • STAR
  • ODV

Flat rupture discs

Flat rupture discs from REMBER offer you fragmentation-free opening across the full width of the vent. Can be produced in virtually any size from DN 20 to DN 1400, for very low pressures from 15 mbarg and with low burst tolerances.

Bespoke rupture discs for special applications

Bespoke rupture discs are used in applications in which individual parameters such as size, space restrictions, leak-tighteness or unusual connections require special consideration. Our specialists manufacture your rupture discs exactly to your specifications – for even greater safety in highly complex systems, special installations or specific OEM applications. We use a variety of materials to adapt our solution to your burst pressure, temperature and corrosion resistence requirements, e. g. stainless steel, nickel, Monel, Inconel, Hastelloy, tantalum, titanium, zirconium and precious metals or high performance plastics.

Breather valve

The ELEVENT pressure and vacuum relief valve provides optimum protection against overpressure and vacuum for vessels and tanks with low design pressures. It assures a constant and controlled level of pressure in the tank. ELEVENT not only prevents fugitive emissions of gas, or other pollutants, but also prevents the development of explosive mixtures of substances and eliminates the potential danger of air entering the system. The standard operating ratio is up to 95 % of the minimum response pressure. ELEVENT is used in the oil and gas industries, food processing, the chemical and pharmaceutical sectors and power plant technology. The optimised ”air cushion“ sealing principle provides a smooth valve stroke and an extremely reliable leak-tight seal. This prevents abrasion and valve chatter. The metal housing is made from deep-drawn stainless steel. For more information please download our new process safety brochure and do not hesitate to contact us!
