Ductile Iron Pipes: Reliable Infrastructure for Modern Water Systems

In today’s rapidly growing urban environments, reliable and long-lasting infrastructure is essential. Ductile iron pipes offer an ideal solution for modern water, sewage, and drainage systems, thanks to their strength, corrosion resistance, and design flexibility.

Comprehensive Product Categories

Our ductile iron pipe offerings cover a wide range of applications:

·  Water supply and drainage pipes

· Thermal pipes

·  Sewage and jacking pipes

·  Polyfluoroester, argon resin, and epoxy ceramic lined pipes

·  PE-lined and zinc-aluminum alloy coated pipes

·  Self-anchored and drag-resistant pipes

Each product is available with matching pipe fittings to ensure seamless integration into various municipal and industrial systems.

Global Standards and Customization Options

We manufacture ductile iron pipes according to international standards such as ISO 2531, EN 545, and EN 598, offering K class and C class strength grades to meet the diverse needs of construction projects around the world.

Pipes are available in diameters ranging from DN80 to DN2600, and standard lengths of 8.15m, 6.0m, or 5.7m — with other options available upon request.

Flexible Connection Systems

Our ductile iron pipes support multiple connection types, including:

·  T-type interface for simple push-on joints

·  GT-type interface for enhanced sealing

·  Self-anchor interface for high-pressure or unstable ground conditions

These options make installation faster and more adaptable to various environments.

Advanced Coating Systems

To meet environmental and operational demands, we provide a variety of internal coatings such as:

·  Ordinary, high-sulfur, or high-alumina cement

·  FBE epoxy powder

·  Polyurethane (PU) or Polyethylene (PE) lining

For outer coatings, options include:

·  99.99% zinc + black asphalt (70 microns)

·  Zinc-aluminum alloy + epoxy paint

·  PU outer coating or fully customized solutions

These coatings provide superior corrosion resistance and ensure extended service life in aggressive soils and water conditions.

With proven durability, a wide range of specifications, and full compliance with international standards, our ductile iron pipes offer the strength and reliability essential for today’s infrastructure. Whether you’re planning a new water network or upgrading an existing system, we offer the flexibility and performance your project demands.
