Ductile iron pipes are actually a type of iron pipe, an alloy of iron, carbon, and silicon. These water pipes are primarily composed of graphite material, existing in a spherical form with a grade of 6-7. The manufacturing materials have been significantly improved, combining the inherent properties of iron with the performance of steel. This type of iron pipe boasts numerous advantages, including excellent corrosion resistance, good sealing performance, easy installation, and is mainly used for municipal water supply, enterprise water supply, gas transmission, and more.
