The Advantages of Kurimoto Ductile Iron Pipe ©Strength J ©Corrosion Resistance / Manufacturing Line and Quality Control Lots of pipes run deep underground and crawl across the surface of the land. Pipes carry critical drinking water, beneficial irrigation water, and gas that serves as an energy source, supporting our everyday lives. And it is not only water and gas that they carry. There are pipes to keep rivers from overflowing their banks, and pipes to provide water after earthquakes or other disasters occur. Pipes support our society simply and in a wide variety of fields. It is safe to say...

The Advantages of Kurimoto Ductile Iron Pipe The Advantages of Kurimoto Ductile Iron Pipe #Strength of Ductile Iron Pipe. Ductile Iron Pipe far outshines other pipe materials in terms of strength; this owes to the spherical shape of the graphite in its composition. The spherical shape minimizes the surface area, maintaining the connectivity of the iron base, which yields our superior strength ratings. Spherical graphite crystals are made by adding small amounts of magnesium and cerium during the casting process. The resulting stress on the graphite is low, even when focused, yielding remarkable...

The Advantages of Kurimoto Ductile Iron Pipe Pipes not only need to be strong and water-tight, they need to resist corrosion. Given that much pipe is laid underground, it is critical to prevent the onset and spread of corrosion. This leads to a longer lifecycle for pipe. Pipes and FittingsSPECIFICATION BS EN 545/598 ISO 2531•Tensile strength and elongation of pipes and fittings Is it possible to prevent the onset and spread of corrosion? The electrical resistance of Ductile Iron Pipe is very high; this is one factor helping to prevent corrosion. In addition, the carbon and silicon molecules within...

FITTINGS •Dl Fittings Simply by inserting the outlet pipe into an inlet pipe with a rubber ring attachment, the connection is made easily, quickly and completely. With just a rubber ring to connect the pipes, our process is much more economical. By inserting the outlet pipe, the valve of the rubber ring is contracted, maintaining a water-tight seal. The heal portion of the ring adheres to the convex portion of the inlet pipe, which prevents the ring from coming loose. The outlet has a gradient, which makes it easy to lay pipe. If the internal pressure increases, the rubber ring becomes even —Q...
