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.

Contributing to reduced downtime through the use of cutting-edge CPL technology.

The SFD type (S = Sublimated; FD = Forward) is a versatile rupture disk suitable for use under various process conditions. It is manufactured using REMBE's proprietary "Contour Precision Laser Ring (CPL) technology," which eliminates common industrial concerns such as early rupture due to mechanical scoring, corrosion of the scored area, and pinholes. If unexpected issues arise, costly downtime may occur. The CPL technology extends the lifespan of the rupture disk, ensuring the highest quality and precise rupture operation control even under the most severe environmental conditions. 【Benefits of Use】 ★ Low burst pressure design – Excellent protection for safety valves ★ Suitable for gas, two-phase flow, and viscous media, maximizing the number of installation locations ★ Capable of accommodating a wide range of process conditions – Using the same type of rupture disk leads to significant benefits in installation, procurement, and maintenance inspections ★ The manufacturing method using precision laser technology reduces downtime caused by early rupture due to mechanical scoring, corrosion of the scored area, and pinholes.

High performance for low pressure applications

The ODV type is a three-layer structure tensile rupture disk designed primarily for low to medium pressure applications. The three-layer structure consists of an upper rupture layer (O), a seal membrane layer (D), and a vacuum support layer (V) facing the process. It provides a high level of performance and durability, making it a cost-effective solution for a wide range of process conditions. The rupture layer, which plays a crucial role in determining the rupture pressure for accurate full-bore rupture release, is manufactured using REMBE's unique production process with precision laser technology. The ODV type is an excellent pressure relief solution for process conditions across various industries. It can operate under conditions with a relief pressure as low as 0.05 bar g, making it suitable for gas, vapor, liquid, and two-phase flow applications. The tensile rupture disk ODV type, which can be mounted at a seat angle of 30°, features a design that prevents fragment dispersion and is available in nominal diameter sizes from DN20 to DN600 (3/4"-24"), making it an ideal solution to meet various process conditions. 【Applications】 ★ Power plants, turbines, condensers, chemical industry, petrochemical industry, process vessels, chemical reactors, storage tanks, refineries, etc.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

In facilities operating nurse call systems, we have made the bed exit sensor wireless, allowing it to notify in conjunction with the nurse call system. By simply connecting the mat sensor "Foldable Thin Matt-kun," the body movement call "Ugo-kun," and the wheelchair body movement call "Ayumi-chan" to the transmitter HB-RS, you can make the bed exit sensor wireless. The infrared sensor "Just Place Pole-kun" has the transmitter HB-RS built-in. This helps prevent accidents caused by falls, slips, or wandering, contributing to the efficiency of medical operations. 【Features】 ○ Wireless conversion by simply connecting existing sensors to the transmitter HB-WSK. ○ The bed exit sensor notifies wirelessly in conjunction with the nurse call system. ○ Up to 5 transmitters can be registered with a single receiver. ○ The communication distance between the transmitter and receiver is approximately 10 meters. ◎ For more details, please contact us or download the catalog.
