Ductile iron pipes are key components in water supply infrastructure, thanks to their excellent strength, durability and corrosion resistance. Kubota makes full use of its proprietary casting technologies, rooted in more than a century of experience, in offering an extensive lineup of products: ductile iron pipes of diverse nominal diameters (75–2,600 mm) and highly functional joints, designed to ensure earthquake resistance and prevent disengagement. Kubota began exporting early on, to contribute to stable supplies of water outside Japan. Nine-meter pipes (world's longest) and other highly competitive products have been exported to more than 70 countries in the world. In 2007, Kubota established the first ductile iron pipe manufacturing and sales company in India to better meet local needs. This company delivers quality products not just in India, but also to countries in Southeast Asia and the Middle East that must address pressing needs for water infrastructure to cope with rapid economic growth. While taking full advantage of the experience and expertise Kubota has acquired in Japan, an advanced nation in water infrastructure, the Company doesn't just supply products, it also actively works to design pipelines used in building highly reliable infrastructure for efficiently delivering clean water.
