Ductile Iron Sewer Pipe with High Alumina Cement Lining and Zinc Coating
Brand TOPSUN
Product origin China
Delivery time 30 days
Supply capacity 10,000 tons per year
Ductile Iron Sewer Pipe is specifically engineered for aggressive sewer environments, featuring a robust zinc coating and an internal high alumina cement lining. This dual-protection system offers superior resistance to hydrogen sulfide corrosion, microbial-induced corrosion, and abrasive wastewater flows, making it the ideal choice for municipal sewage force mains, industrial effluent lines, and wastewater treatment plant networks where durability is critical.
We utilize advanced centrifugal casting technology to ensure pipe wall consistency and high structural integrity. Our high alumina cement lining is rigorously formulated to withstand low pH conditions and chemical attacks that degrade standard linings. This technical focus, combined with our high-volume production lines, allows us to maintain consistent quality across large orders and execute major projects for municipal authorities and international engineering contractors.
Supported by significant production capacity and strategic raw material reserves, we keep substantial inventory of finished pipes and specialized components. This enables direct factory shipments and reliable lead times for global projects. Our products are trusted in demanding applications worldwide, from coastal city sewer systems to industrial park discharge networks, ensuring long-term performance with minimal maintenance.

The Ductile Iron Sewer Pipe with High Alumina Cement Lining and Zinc Coating is engineered for exceptional performance in aggressive environments. Its key feature is the superior internal protection provided by the **high alumina cement lining**, which offers outstanding resistance to acidic conditions, hydrogen sulfide corrosion, and abrasive wastewater flows. Externally, a robust **zinc coating** acts as a sacrificial layer and effective barrier against soil corrosion and electrochemical attack.
This pipe combines the inherent strength and impact resistance of **ductile iron** with this advanced dual-layer protection system. The result is a product with exceptional load-bearing capacity, perfect for deep-bury applications and installations under roads. The combination of the hard, smooth interior lining, which maintains flow efficiency and resists buildup, and the tough external coating ensures a long service life with minimal maintenance, providing a cost-effective and reliable solution for the most demanding sewer and industrial effluent applications.
Ductile Iron Sewer Pipe with High Alumina Cement Lining and Zinc Coating is specifically engineered for demanding wastewater applications. It is ideally suited for municipal sewage force mains and gravity sewer systems, particularly in areas with aggressive soils or where hydrogen sulfide corrosion is a concern. The pipe's superior corrosion resistance also makes it perfect for industrial effluent lines, wastewater treatment plant intake and discharge networks, and coastal sewer outfalls.
This specialized pipe excels in challenging environments where standard concrete or PVC pipes may fail. Its robust construction is specified for deep-bury installations, crossings beneath railways and highways, and in aggressive soil conditions. The combination of high alumina cement lining and zinc coating provides long-term protection in applications involving chemical plants, mining operations, and municipal systems conveying abrasive or temperature-fluctuating wastes, ensuring reliable performance and extended service life.
