Our ductile iron pipes combine the strength of steel with the corrosion resistance of cast iron, making them ideal for modern water and wastewater systems. Through advanced spheroidization treatment, our pipes achieve high tensile strength and excellent impact resistance, ensuring reliable performance under high-pressure conditions. The pipes are internally lined with cement mortar or epoxy resin for enhanced flow efficiency and corrosion protection, while the external zinc coating with anti-corrosion finish provides long-term durability. Available in various classes (K7/K8/K9) and diameters, our products meet demanding municipal water supply, drainage, and industrial applications.

Our ductile iron pipes are produced using state-of-the-art centrifugal casting technology with computer-controlled molding and pouring systems. The production line features automated annealing furnaces for precise heat treatment, real-time nodularity monitoring equipment to ensure graphite spheroidization rates exceed 90%, and CNC machining centers for accurate socket and spigot processing. Integrated testing systems including hydrostatic pressure testing, ultrasonic thickness measurement, and coating adhesion checks guarantee consistent quality throughout the manufacturing process. Our smart factory supports customized lengths, thickness classes, and special lining requirements to meet project-specific needs.

In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.

Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
