The horse and push bolt are made of corrosion-resistant alloy! They demonstrate disengagement prevention performance of 3D kN or more!
"Kamik 90" is a disengagement prevention fitting for mechanical joints handled by Kurodaito. It exhibits 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 soft contact 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 penetration. 【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 penetration ■ 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.

Company information
The era is now in a state of upheaval. From the individual to the whole, from development to harmony, and then back from the whole to the individual, human thought is also expanding from the local to the global, and then to the universe. Accordingly, companies are dynamically changing their management strategies. The "Kurodai Group," amidst such trends, continues to pursue the ideal form of a company—its role in society. In other words, companies cannot survive in isolation; they must act as members of society, manage with respect for nature, and consider how they can contribute to society as businesses. We aim to build true prosperity through coexistence, deepening our connections with each employee, each product, each customer, each company, and society as a whole.
