The promotional video for the super-efficient construction Grojo Joint has been renewed!

Turn it and click, connection complete! Are you familiar with stainless steel piping that thoroughly reduces labor on-site? We have a wide range of sizes from 40A to 250A.

In response to the requests from many customers, we are expanding the campaign target areas and duration! We have prepared a "20% off the regular price" campaign exclusively for equipment construction companies that are adopting the Groojoint for the first time. ■ Application Period: February 3, 2025 - End of February 2026 ■ Eligibility Conditions: Projects that will begin delivery by the end of March 2026 (Ongoing projects and projects with confirmed adoption are not eligible for this campaign) ■ Limited Conditions: Exclusively for equipment construction companies located in Hokkaido, Tohoku, Kyushu, the Nagoya area (Aichi, Gifu, Mie), and the Kansai area (Osaka, Kyoto, Hyogo, Nara, Shiga, Wakayama) that are adopting Groojoint for the first time. Please take this opportunity to utilize the stainless steel piping "Groojoint 2.0MPa (250A is 1.0MPa)," which has achieved outstanding labor-saving capabilities for a wide range of applications such as industrial plants and high-rise buildings. We also have Groojoint 3.5 (3.5MPa specification) available.

We support various processing methods such as flange processing and roll grooving! We propose shapes suitable for your application.

"Stainless Prefab Processed Pipe" is made of stainless steel with excellent corrosion resistance, lightweight, and offers superior workability on site. It can be used for a wide range of applications, including building equipment piping, plant piping, and water supply and drainage piping. Since all components are produced in our factory, we can accommodate custom processing requests, and we provide high-quality and uniform products through strict inspections. Please feel free to contact us when you need our services. 【Features】 ■ Reduces labor hours for construction, shortening the construction period ■ On-site work is easier and faster compared to on-site processing ■ Savings on fittings through branching processing (including small diameters) ■ Quality is stable as processing is done in the factory ■ Piping with excellent corrosion resistance that considers the global environment *For more details, please refer to the PDF document or feel free to contact us.

Significantly reduces the effort required for cleaning and inspection compared to conventional bucket strainers!

The Glow Bucket Strainer is a product that allows for easy and safe cleaning and inspection. When opening the upper cover, there is no need for any bolt or nut tightening work, and the upper cover can be removed with a single touch. Maintenance can be performed without tools for body diameters up to 150A. The product weight has been reduced to about one-third compared to conventional flange types, making it easier to handle. Since the face-to-face dimensions and filtration area can be customized, it can be replaced in existing spaces. 【Features】 ■ Easy and safe cleaning and inspection ■ Upper cover can be removed with a single touch ■ Safety is ensured during opening operations from the top ■ Lightweight and compact ■ Face-to-face dimensions and filtration area can be customized *For more details, please refer to the PDF materials or feel free to contact us.

A shape born from the idea of easy inspection. Maintenance can be performed without tools.

The "Glow Bucket Strainer" is a groundbreaking strainer that maximizes the performance of our "Glow Joint." During open cleaning and inspections, it requires no bolt or nut tightening work, and maintenance can be performed without tools up to a main body diameter of 150A. The product weight has also been reduced to about one-third compared to conventional flange types, making it easier to handle. 【Features】 ■ Adoption of the Glow Joint System ■ Cover removal time is less than about 1/10 compared to flange types ■ Safe and easy work can be performed by carrying out open operations from above *For more details, please refer to the external link page or feel free to contact us.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

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 to 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 you require a detailed technical explanation, please contact us.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.
