A Proven Standard for Modern Water Infrastructure

Water transmission systems require materials that are strong, durable, corrosion-resistant, and economically viable over decades. Ductile iron pipe (DIP) has consistently outperformed alternatives in large-scale water supply networks across the globe — and for good reason.

At Pipekom, we specialize in supplying ductile iron pipes for water supply projects throughout the Middle East and Africa, ensuring maximum lifespan, minimal maintenance, and full standards compliance.


📌 What Is Ductile Iron Pipe?

Ductile iron pipe is a type of cast iron known for its high tensile strength, impact resistance, and flexibility under pressure. It combines the corrosion resistance of cast iron with the ductility and toughness of steel, making it an ideal choice for:

  • Long-distance water transmission

  • Urban and municipal water supply networks

  • Pressurized pipelines and pumping systems


📈 Global Demand & Market Data

  • 🌍 Over 600,000 km of ductile iron water pipelines have been laid globally.

  • 💰 The global ductile iron pipe market is projected to reach USD 18.2 billion by 2030, with a CAGR of 5.1%.

  • 💧 In the Middle East and North Africa (MENA), water transmission losses are as high as 30% — prompting governments to invest heavily in leak-resistant materials like DIP.
