Webinar: "Clean Pressure Release"

Attention engineers and production managers in the oil, gas, chemical, and petrochemical fields! *White paper available for distribution.

Our company is a manufacturer of explosion protection and pressure relief products headquartered in Germany. Engineers in the oil, gas, chemical, and petrochemical sectors have relied on rupture discs for many years to quickly and reliably relieve unwanted and excessive pressure or vacuum within production processes. However, the early rupture discs were very simple, consisting of a flat metal piece installed between flanges that was weakened at a predetermined point using a mechanical scoring method (grooving) to open. Advancements in technology and design have dramatically improved quality and reliability, eliminating long-standing concerns such as pinholes, leaks, premature failures, and frequent replacements. *We are also offering a white paper in addition to our product catalog. The white paper discusses the challenges faced with rupture discs in the past and the current rupture discs that have resolved those issues. [Past Challenges] - Frequent leaks - Many premature failures (ruptures) - Need for frequent replacements

Reusable rupture disk. [Exhibiting at INCHEM TOKYO 2025]

The KUB type is a long-lasting rupture disk. The KUB type is a special rupture disk that is extremely robust and high-performance, with the burst pressure defined by the Euler formula's buckling load calculation method. Unlike rupture disks manufactured by weakening part of the material, it is a product of REMBE's unique high technology that incorporates a buckling pin for precise full bore opening. Additionally, it features a smooth surface without weakened areas in the disk material, making it very robust and eliminating the risk of damage from misoperation, incorrect installation, or drops (from a height of about 1 meter). With a two-layer structure consisting of a seal membrane layer and a burst layer, the surface of the seal membrane layer that comes into contact with the process medium is smooth and free of scratches. It uses a highly sealable diaphragm, minimizing the risk of damage due to corrosion. The KUB type, with a maximum operating pressure ratio of 98%*, is designed to be strong against metal fatigue not only for high-pressure applications but also under harsh process conditions for gas, steam, liquid, and two-phase flow applications. Its unique manufacturing method allows it to be used even for liquid-only applications, greatly diversifying installation locations and simplifying installation, maintenance inspections, and procurement processes. *Varies by application.

2-in-1 Rapture Disk

The two-direction rupture disk type ZW opens in one direction in the case of specified excess pressure and in the other direction in the case of vacuum. It is primarily used in storage tanks for processes involving gases or liquids. The rupture disk allows for an operating pressure ratio of 80% (*) in the excess pressure direction and 70% (*) in the vacuum direction. The ZW type can be equipped with an optional burst signal device that includes a proximity sensor. When the rupture disk bursts in one of the two directions, it sends a burst signal to the process control system connected to the SNR. By combining the function principle of the buckling pin inverted rupture disk type KUB and the three-layer tensile rupture disk type ODV, one rupture disk can respond to two different pressure values. * This varies depending on each application.
