A pipe thread with strong joint strength! Achieves excellent earthquake resistance, pressure resistance, and durability!

The "Rolling Nipple" is a pipe thread that has strong bonding strength with fittings and excels in earthquake resistance, pressure resistance, and durability. Traditionally, pipe threads used in piping fittings were mainly produced through cutting processes, but this led to various issues in performance due to the reduction of effective pipe thickness and inconsistencies in thread precision and surface smoothness. Our product achieves a high-precision and smooth thread surface through rolling, improving the adhesion between male and female threads. It resolves the issues associated with cutting threads. 【Features】 ■ Earthquake resistance ■ Pressure resistance ■ Durability ■ Sealing performance *For more details, please refer to the catalog or feel free to contact us.

Custom-made insulating bolts and nuts.

The bolts and nuts are manufactured and sold not only based on the distinction between iron and stainless steel but also according to specifications regarding material, strength, and plating. Since they are made to order, there is flexibility in the shape of the bolt body and insulating parts. The bolts and nuts can comply with not only JIS standards but also ASTM and ANSI/ASME, and various test certificates can be issued.

We will be exhibiting at the "Construction Technology Fair 2025 in Chubu," which will be held at Port Messe Nagoya on December 4th (Thursday) and 5th (Friday) of the 7th year of Reiwa. The Nepurasu Method National Association will showcase the "Nepurasu Method" for ditch renovation. If you have any issues with ditch repair or improvement work, please stop by our booth. We will provide various proposals based on past cases. Additionally, the Nepurasu Method National Association is looking for product manufacturing partners and construction partners in the Chubu region. We welcome companies that want to "manufacture and sell products for the Nepurasu Method" or "try their hand at construction" to visit us. In addition to the ditch renovation method, we will also be displaying newly developed flood control products.

We are pleased to announce a web seminar hosted by our company. 【Generative AI Utilization Seminar: The First Step to Starting with Generative AI Together】 The currently popular generative AI (such as Copilot and ChatGPT) is a new technology that is useful in various everyday and work situations, including writing, information search, and translation. Unlike previous AI, it has evolved to suggest ideas that humans may not think of and to offer greater flexibility in operation. However, many people may feel that it seems "difficult" or "I don't know where to start." In this seminar, we will start with the basics of generative AI and clearly explain practical utilization methods through examples and demonstrations. We will also carefully introduce points to be aware of when using it. After participating, you should be able to take the first step in mastering generative AI as your "partner." Would you like to experience the future of work with your own hands? We look forward to your registration. 【Timetable】 - Basics of Generative AI Utilization - Introduction of FCS Utilization Examples - Demonstration of Office Product Integration Using Copilot - Q&A Session
