Corresponding to a high standard of sanitary measures.

KUB Clean has set a new standard in the field of sanitary rupture disks. KUB Clean completely eliminates leaks and boasts excellent durability, resulting in a product that is impeccable for sanitary use. The most outstanding feature: KUB Clean can be easily installed on existing Tri-Clamp flange systems, meeting all requirements for sanitary design and is ideal for CIP and SIP. The surface of the sealing membrane is smooth, and it can be directly attached to the Tri-Clamp flange system with the seal integrated, eliminating any grooves, recesses, or notches that could trap dirt or production residues during production or cleaning cycles. Therefore, KUB Clean is ideal for aseptic and sanitary applications.

High airtightness and a design that is difficult to leak! A suitable inverted rupture disk for isolating safety valves.

The "KUB V-type" protects safety valves from corrosive or sticky process media by installing a rupture disk before the inlet of the safety valve. It has been certified for durability against back pressure of up to 135% of the specified burst pressure (*), and it allows for safety valve testing on-site without the need for removal for maintenance. During normal operation, the safety valve is isolated from the process media, allowing for the use of safety valves made from inexpensive materials. 【Features】 ■ Extended lifespan of safety valves and longer intervals between after-service ■ Reduced maintenance inspection costs for safety valves ■ Use of safety valves made from inexpensive materials is possible ■ High airtightness and a design that minimizes leakage * This varies depending on each application. * For more details, please refer to the PDF materials or feel free to contact us.

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.

Protecting low-pressure design tanks in the pharmaceutical, food, and chemical industries from excessive pressure and vacuum. Capable of handling an extremely low pressure range, with a standard operating pressure ratio of 95% of the minimum burst pressure!

The ELEVENT pressure and vacuum relief valve protects low-pressure designed tanks and containers from excessive pressure and vacuum, while maintaining the pressure inside the tank or container at a constant level. ELEVENT not only prevents the leakage of gases and other contaminants but also eliminates the potential danger of air intrusion into the equipment while suppressing the generation of substances that could lead to explosions. The standard operating pressure ratio is 95% of the minimum burst pressure. ELEVENT is used in the oil and gas industry, food processing, chemical and pharmaceutical fields, and power plant technology. The optimized "air cushion" airtight principle enables smooth valve strokes and the highest level of airtightness, preventing wear and valve chattering. The metal housing is made of deep-drawn stainless steel. ▶ Benefits of Use ▸ Capable of handling extremely low pressure ranges (±2 mbarg) with a compact size for overpressure and vacuum protection ▸ High reliability of airtightness ▸ Pressure setting changes can be made later ▸ Excellent corrosion resistance with E-CTFE and PFA coatings, making it suitable for corrosive atmosphere applications *For more details, please download the materials or feel free to contact us.

In civil engineering work conducted near residential areas, schools, hospitals, and stores, consideration for noise and neighboring properties is essential. In particular, the sound generated during vehicle passage and the installation and removal of temporary roads, access routes, and heavy machinery work yards can be concerning. Hyper CLT sheets are civil engineering materials that utilize wood CLT. As wooden sheets, they can be used as alternatives to steel plates, for muddy ground measures, ground protection, heavy machinery scaffolding, and worker pathways. Due to the unique properties of wood, they provide a different experience compared to metal sheets, making them easy to recommend in sites where reducing metal noise and considering neighboring properties are priorities. Additionally, the texture of wood can soften the impression of the site, contributing to the creation of environments that emphasize environmental consideration and safety awareness. The 5×10 sheet weighs approximately 230 kg, and the 5×20 sheet weighs about 460 kg, making them lightweight and easy to handle even with small machinery. They can also be utilized as a registered technology under the Ministry of Land, Infrastructure, Transport and Tourism NETIS "TH-250021-A" for innovative ideas, safety measures, and neighbor considerations in public works. We also accept requests for materials and consultations for implementation.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding methods for repairs can cause changes in the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even 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 or download the catalog.
