Ductile Iron Pipes
The origin of Kubota's ductile iron pipes goes way back to 1890's. At that time, there were various infectious diseases spread within Japan. This triggered Gonshiro Kubota, our founder, to produce the first iron pipes in Japan. Since then, our long technical experience realized ductile iron pipes with excellent strength, durability and corrosion resistance, which today became the key components of water supply infrastructure.
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 (DN80—DN2,600), highly functional joints such as earthquake resistant joints and restrained joints. It is our Centrifugal Casting technology, first in the world to put it into a practical use, which led to the success of providing high quality large scale ductile iron pipes and their stable production.
These pipes were exported outside of Japan early on, to contribute to stable water supply. We have exported iron pipes to more than 70 countries in the world today. In the Middle/Near East, a major destination of world longest nine-meter pipes, Kubota products are appreciated for their quality and workability. In the rapidly growing Southeast Asia, Kubota is contributing to the improvement of infrastructure through ODA projects.
Also, by taking full advantage of the experience and expertise acquired in Japan, we actively work not just only as the supplier of the pipes but also as the designer of pipelines. Kubota will continue contributing to more reliable and efficient water supply infrastructure worldwide.

Overwhelming Strength and High Durability
Kubota's ductile pipes are known for its excellent strength and high durability. Their strength and ductility offer high level safety against internal and external pressure. Also, centrifugally mortar lining cast and epoxy resin enamels and varnishes realize high durability.
Wide Variety of Joints and Thickness
Kubota offers wide variety of joint and thickness to meet various needs and conditions. Thanks to our richness of joint format and pipe variations, including such unique products as restraint joints and earthquake resistant joints, Kubota is able to plan economic and rational pipeline architecture.
Our ductile iron pipes enjoy low rate of accidents based on per buried distance as well as very few accidents during the earthquake. The pipes are very easy to maintain and even when they are faced with accidents, they can be repaired in short time.
Kubota's ductile iron pipes are available in variety of size and for various needs.
