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.

Helium leak tested high airtightness rupture disk.

The UKB LS consists of a customizable housing, an inverted rupture disk, and a three-section knife. When the specified burst pressure is reached, the rupture disk bursts open towards the knife. This design allows for the lowest burst pressure while also enabling high vacuum conditions. The rupture disk and housing are micro-welded, and all components are made of metal, ensuring maximum airtightness. A maximum leakage rate of 10^-10 is achievable. With various types of connections available, we provide pressure relief units that perfectly fit any application, including high-purity processes. Despite the numerous variations, several "standard" sizes have been established over the past few decades for installation between commercially available flanges.

Long-selling classic Rapture Disc

This is a representative rupture disk developed several decades ago. Even today, this tension-type rupture disk is widely used in simple applications that handle medium to high pressure, such as pumps in the hydraulic, chemical, and petrochemical industries. The standard operating pressure ratio is 70%* of the minimum burst pressure. The burst pressure is determined by the thickness of the material and its tensile strength. It also accommodates the incorporation of a vacuum support layer with full vacuum resistance. 【Benefits of Use】 ★ Easy to use ★ Wide range of materials can be used *It may vary for special applications.

Protective for CBS type intermodal transport tank container with a tension type rupture disk.

The CBS type rupture disk protects intermodal transport tank containers, which have particularly high demands for heat resistance, corrosion resistance, and airtightness in pressure relief devices (rupture disks). It is used additionally below safety valves (e.g., valves manufactured by Fort Vale) to protect the safety valve from corrosion caused by the product and to ensure the airtightness of the safety valve. The operating pressure ratio of the rupture disk is 80% of the minimum burst pressure*, and it can be directly mounted between flanges, opening in a star shape with no fragment dispersion. It is fully compatible with vacuum and overpressure applications and can be used with liquid or gaseous media. The CBS type design has the highest level of airtightness and is mounted with a protective ring located below the outlet gasket. To enhance corrosion resistance, it is also possible to add a lining on top of the inlet gasket if necessary. *This may vary for special applications.

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.
