Ductile Iron Sewer Pipe with High Alumina Cement Lining and Zinc Coating

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.
