Ductile Iron Pipe (DN700)

Ductile Iron (DI) pipes have good mechanical properties, in addition to high durability and strength, making them ideal for high-pressure applications. Ductile Iron pipes are used extensively in systems transporting potable water, industrial water, irrigation water, and pressure sewage. Metallic pipes, primarily Cast Iron, had been used for over two centuries for water and wastewater transportation.

Ductile Iron pipes, belongs to the family of Cast Iron, is manufactured by treating the molten low-sulfur base iron with magnesium under closely controlled conditions. This process results in a startling change in the metal, characterized by the free graphite in Ductile Iron being deposited in the spheroidal or nodular form. This leads to maximum continuity of the metal matrix, thereby forming a stronger and tougher ductile material with high ductility and impact strength.
