Ductile iron pipe is a kind of cast iron, belongs to alloy of iron, carbon and silicon. Ductile iron graphite is in the form of spherical, the general size of graphite 6-7 grade, the quality requirements of the cast pipe of the ballification level control for the 1-3 (ball rate ≥ 80%), thus the material itself machinery performance has been improved better, with the nature of iron, steel performance, mechanical properties are better.
In the low-pressure pipe network, ductile iron pipe has safe and reliable operation, low damage rate, construction and maintenance convenience, excellent anti-corrosion performance.
