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

Automatic reclosing and reusable explosion-proof door

▶ Purpose In the drying process of the food industry, explosive atmospheres often occur. Due to the high likelihood of embers and hot surfaces, the preparation of explosion-proof devices is essential. The ring-type dryer has a functionally elongated design, so if the pressure relief device remains open after an explosion, the so-called chimney effect can exacerbate post-explosion fires. REMBE's explosion-proof door model ETX automatically closes after the explosion pressure is released, preventing post-explosion fires, that is, stopping the inflow of oxygen into the device. The ETX model remains undamaged after pressure relief and is reusable. ▶ Benefits of Use ▸ Prevention of post-explosion fires due to chimney effect ▸ Automatic re-closing ▸ Reusable ▸ High discharge efficiency ▸ Heat tracing for snow melting and freeze prevention (optional)

With Q-Rohr, we provide the best possible explosion safety guarantee while using the optimal layout for your production facility.

Safety and operational efficiency can coexist. Q-Rohr enables explosion venting without flames or dust in a sealed indoor environment. There is no need for complex ducting and the associated rearrangement of production equipment for outdoor venting. With Q-Rohr, we provide the best possible explosion safety guarantee while utilizing the optimal layout for your production facility. Furthermore, Q-Rohr is also very advantageous in terms of running costs. By eliminating vent ducts, you can save not only on installation costs but also on maintenance and upkeep expenses. ▶ Applications Q-Rohr is ideal for indoor installations where there is a risk of dust or gas explosions. It offers a wide range of flexible installation options, so many new plants are directly equipped with Q-Rohr. Modifications are also easily possible. Q-Rohr can be used to protect filters, dryers, and cyclones, and is applicable for gases, hybrid mixtures, metal dust, molten dust, fibers, and more. ▶ Mechanism Flame gases reaching up to 1,500°C are cooled very efficiently within a specially developed stainless steel mesh filter inlet by REMBE. This reduces the amount of gas discharged and helps to quell explosions.

Economic shutdown of filters, dust collectors, and raw gas lines.

**Application** In the event of an explosion, the Q-Flap RX explosion isolation flap valve effectively protects plant components in almost all industrial sectors. Additionally, the Q-Flap RX is ideal for suction lines of filter dust collectors and intake lines of mills. Piping with a nominal diameter of DN400 is primarily used in decentralized extraction systems in the pharmaceutical and chemical industries, while piping with nominal diameters from DN450 to DN710 is used in centralized dust collectors in the grain and food industries. Piping with nominal diameters from DN800 to DN1250 is used in the wood and heavy industries. To meet the highly diverse demands of various industries, the Q-Flap RX product range offers three design versions. Products up to nominal diameter DN710 are equipped with inspection flaps, while products above that size feature a modular design. This allows for easy maintenance and servicing for any pipe size.

Elevator explosion vent - lightweight with high discharge efficiency

The Q-Ball E type ensures safe release of explosion pressure within the operating area. Flames are efficiently cooled and extinguished inside the Q-Ball E type, eliminating pressure effects from explosions. The Q-Ball E type is suitable for frameless explosion venting of low-strength designed mechanical conveyors, such as bucket elevators. It can handle explosion indices based on KSt values of up to 200 bar x m/s. The installation nominal diameter of the Q-Ball E type is designed to perfectly fit the standard sizes of mechanical conveyors like elevators. There is no need for flange adjustment work. The Q-Ball E type is lightweight, so reinforcement of the conveyor shaft is also unnecessary. A new frameless explosion venting principle has been developed for all surfaces, ensuring the Q-Ball E type provides the highest venting efficiency. As a result, it is possible to minimize the required explosion venting space.

Frame-less explosion vent for dynamic vibrating machines such as vibrating screens.

【Lightweight and High Dissipation Efficiency】 The Q-Ball S type guarantees safe indoor explosion dissipation within the operating area. It effectively cools the interior of the Q-Ball S type, preventing the effects of flame propagation and explosion pressure. The Q-Ball S type can accommodate up to 265 bar*m/s (Kst value) and is a frameless explosion dissipation outlet specially developed and customized for plant components with high dynamic requirements for vibration and oscillation. With its specially designed lower structure and minimal output-to-weight ratio, the Q-Ball S type can be directly mounted onto vibration systems. By applying the newly developed spherical extinguishing efficiency, there are no costs incurred for modifications or changes. The Q-Ball S type guarantees maximum dissipation efficiency while minimizing the required dissipation area.

Explosion venting port resistant to low to medium vacuum and pressure fluctuations.

The dome-shaped single-layer explosion vent type EDP is suitable for use in processes involving medium vacuum or overpressure (up to 70% of the minimum pressure (Pstat) when the explosion vent is open), as well as some pressure fluctuations. It is mainly suitable for air-filled devices, filters, cyclones, and containers that operate under strong vibrations. The standard burst pressure is 0.1 bar (22 °C). 【Mechanism】 As the pressure increases, the explosion vent will rupture at the designated rupture point at the specified pressure, releasing the pressure and flames from within the container or device to the outside.

Recently, fine bubbles, which are tiny bubbles smaller than 100 μm and are referred to as "fine bubbles," have attracted attention in various fields such as the environment, agriculture, food, fisheries, and medicine, due to their ability to impart various functions to liquids. Fine bubbles are classified into two types based on their size: microbubbles and ultrafine bubbles. Recently, there has been a growing interest in ultrafine bubbles, which have a lifespan of several weeks to months. However, listening to the voices of researchers and users reveals some skepticism, which has become one of the issues hindering the spread of fine bubble technology. On the other hand, we have challenged the elucidation of the stabilization mechanism of ultrafine bubbles from a new perspective by enabling the control of number density exceeding 10 billion particles/mL without pressure or concentration operations using our ultrafine bubble generation technology. In this seminar, we will provide a fundamental explanation of fine bubble technology, including the basic physical properties, characteristics and functions, device technology, measurement and evaluation methods, and case studies, to promote research and utilization of fine bubbles based on a correct understanding.

Sekiguchi Iron Works Co., Ltd. will exhibit at the "Minami-Shinshu Environmental Messe 2025" held at S-Bird in Iida City, Nagano Prefecture. This exhibition will be held simultaneously with the "Environmental Industry Trade Fair" taking place the day before. It will be held over the weekend, with many family-friendly events planned. We encourage those who usually find it difficult to visit to take this opportunity to come. Our product exhibition area is located about 10 minutes from the venue. We sincerely look forward to your visit.
