DUCTILE IRON PIPES

 

Ductile Iron Pipe: A Reliable Choice for Water Transportation

Introduction: Ductile iron pipe, also known as ball pipe or ductile cast pipe, is manufactured through high-speed centrifugal casting of centrifugal ductile iron machine. This process involves casting molten iron above No. 18 with the addition of nodularizer, resulting in a durable and versatile pipe.
Features & Benefits:
  • Strength and Durability: Ductile iron pipes are known for their high strength and durability, making them ideal for long-term use in water transportation.
  • Corrosion Resistance: These pipes are highly resistant to corrosion, ensuring a longer lifespan and minimal maintenance requirements.
  • Flexibility: Ductile iron pipes are flexible, allowing for easy installation and adaptability to various terrain conditions.
  • Cost-Effective: Despite their initial cost, ductile iron pipes offer a cost-effective solution due to their long lifespan and low maintenance needs.
Applications:
  • Municipal water supply systems
  • Industrial water transportation
  • Irrigation systems
  • Sewage and drainage systems
  • Fire protection systems
