The "B・B Unit (GX Type)" is a long bend that can bypass a wide variety of obstacles with its long L2 dimension. It allows for safe, quick, and economical construction with minimal materials and fewer joints. The interior coating is epoxy resin powder coating. The exterior coating is corrosion-resistant (zinc alloy injection + sealing treatment + synthetic resin coating in gray). 【Features】 ■ Long L2 dimension ■ Capable of bypassing a wide variety of obstacles ■ Safe, quick, and economical construction with minimal materials and fewer joints ■ Interior coating is epoxy resin powder coating ■ Exterior coating is corrosion-resistant (zinc alloy injection + sealing treatment + synthetic resin coating in gray) ■ Certified by the Japan Water Works Association *For more details, please refer to the PDF document or feel free to contact us.

• Fittings

"Kamik 90" is a disengagement prevention fitting for mechanical joints handled by Kurodaito. It exhibits a disengagement prevention performance of A grade, as defined in the technical standards (draft) for seismic joints of underground buried pipelines by the National Institute for Land and Infrastructure Management, with a performance of 3DkN or more. (D: nominal diameter) The contact ratio of the claw part of the fitting is over 90% with the outer circumference of ductile cast iron pipes, and it makes a soft touch with the ductile cast iron pipes, further reducing the impact on the mortar lining of the inner surface compared to conventional products (Kamik 80). The fitting and the pressing bolt are spherical, accommodating not only disengagement but also entry. [Features] ■ Exhibits disengagement prevention performance of 3DkN or more ■ Contact ratio of the fitting is over 90% ■ The fitting and pressing bolt are spherical, accommodating both disengagement and entry ■ The fitting and pressing bolt are made of corrosion-resistant alloy *For more details, please refer to the PDF document or feel free to contact us.

• Solar mounting brackets and fittings (solar fittings and protective sheets)

The "ABS Method" is a simple device that allows for localized water shut-off in pipelines without requiring special skills, enabling quick operation. We offer two different methods, "Method I" and "Method II," which use different saddles. These methods primarily contribute to leak repair work, installation of shut-off valves, and pipeline relocation projects. 【Lineup】 ■ Method I: Uses the "Stopper Saddle" developed by our company ■ Method II: Uses commercially available saddles with branch valves *For more details, please download the PDF or feel free to contact us.

The special-shaped pipe temporary water supply valve THB-10 requires very little excavation for grounding at the fire hydrant section, allowing for quick restoration work. It can be easily connected to temporary water supply pipes from any direction, is compatible with various sites, and has good workability, accommodating both 40mm and 50mm outlet diameters for temporary water supply pipes. It also allows for large temporary water supply. Even with the outlet installed, the total height remains below 280mm, making it a very compact design that can be installed even with shallow burial. The use of special flanges and bolts allows for both single and double outlet compatibility, making it economical. It is compliant with the inspection standards of the Japan Water Works Association.

• Piping and insulation

The airbag-type water-stopping method (ABS method) involves installing a saddle on the pipeline to be sealed, followed by drilling, and then inserting an airbag at a designated position within the pipeline using a specialized insertion machine. The airbag is inflated to create a localized water stoppage in the pipeline. This method utilizes a simple device that allows for quick localized water stoppage, and it can be used as part of a series of pipeline works rather than as an independent construction project. There are two variations of the method: Method I uses a stopper saddle developed by our company specifically for the ABS method, while Method II uses commercially available saddles with branch valves. It is ideal for reducing construction time and minimizing the area affected by water stoppage. For more details, please contact us or refer to the catalog.
