Product Introduction:

Qingdao Century Ductile Iron Pipe Industry's drainage ductile iron pipes are a top choice for urban drainage network construction. The product range covers DN80 to DN2600mm, with ample stock to meet various engineering requirements. Employing advanced centrifugal casting technology, combined with professional internal and external anti-corrosion treatment, the cement mortar lining on the inner wall significantly enhances its corrosion resistance, effectively withstanding the erosion of acidic and alkaline substances in sewage.

The product combines the corrosion resistance of cast iron with the toughness and strength of steel pipes, achieving a tensile strength of over 420MPa and an elongation exceeding 10%. It is less prone to fracture under external soil pressure, traffic loads, or foundation settlement. The pipe ends feature a flexible joint design, providing excellent sealing and accommodating complex terrain installation needs, significantly reducing the risk of leakage, and ensuring convenient and efficient installation.

Produced in strict compliance with the national standard GB/T 13295—2013, the product has passed dual certifications of the ISO9001 Quality Management System and ISO14001 Environmental Management System. With its exceptional performance, reliable quality, and comprehensive pre-sales and after-sales service, this Ductile Iron Pipe is widely used in municipal sewage, pressure drainage, and sewage lifting projects, providing a solid guarantee for the stable operation of urban drainage systems.
