Product Description
Product Overview
Custom dimensions 6m and 12m DN400 ductile iron pipes manufactured using high-speed centrifugal casting technology with nodulizing agents added to cast molten iron. These pipes are ideal for municipal water supply, gas transmission, and industrial fluid transportation applications.
Key Features & Advantages
Superior Mechanical Properties
Spheroidal graphite structure (grade 6-7) with spheroidization level controlled to grade 1-3 (≥80% spheroidization rate), providing the strength of steel with the corrosion resistance of iron.
Excellent Corrosion Resistance
Multiple coating options available including epoxy resin, polyurethane, zinc-aluminum alloy, and PE film coatings for enhanced durability.
Reliable Performance
Safe and reliable operation in medium and low pressure networks (up to 6MPa) with low damage rates and easy installation.
Versatile Applications
Suitable for trenchless construction, river crossings, road crossings, and building pipeline networks.
Technical Specifications
Available in custom lengths of 6 meters and 12 meters with DN400 nominal diameter.
