This advanced Ductile Iron Pipe combines multiple protective technologies for superior performance and longevity. The pipe's core is manufactured from high-strength ductile iron, providing exceptional impact and load-bearing resistance. Its key innovation is the internal lining of High Aluminum Cement (HAC) mortar, which offers outstanding resistance to acid, sulfate, and aggressive water conditions, ensuring long-term water quality and flow efficiency.
Externally, a robust zinc coating is applied, forming a metallurgical bond with the iron substrate. This layer acts as a sacrificial anode, providing effective cathodic protection to prevent pitting corrosion. This zinc layer is typically further enhanced with a bituminous or polymer seal coat for additional passive protection. The combination of the cement mortar lining and the dual-layer external coating ensures exceptional durability, making it the ideal choice for challenging environments, including corrosive soils and industrial areas.
This specially engineered ductile iron pipe is designed for demanding environments where standard piping solutions may fail. Its high-performance internal lining, made with High Aluminum Cement (HAC) mortar, makes it ideal for conveying aggressive fluids, including sulfate-laden potable water, moderately acidic or alkaline industrial effluents, and softened water. This superior corrosion resistance is critical for pipeline longevity in coastal areas, reclaimed lands, and industrial zones with corrosive soils.
Externally, the synergistic zinc coating and seal coat provide robust protection against severe soil conditions, including stray current electrolysis and acidic soils. Consequently, it is the preferred choice for critical infrastructure projects such as main water transmission lines, sewer force mains, industrial process lines, and subaqueous installations. Its durability ensures a reliable, long-service life with minimal maintenance, offering a cost-effective and resilient solution for municipal and industrial engineers.
This product represents a premium-grade Ductile Iron Pipe engineered for maximum durability and service life in the most demanding environments. The pipe is constructed from high-strength ductile iron, which provides inherent mechanical robustness, excellent impact resistance, and high load-bearing capacity.
The key differentiator of this pipe is its advanced, multi-layered protection system. The interior is lined with a built-in cement mortar formulated with High Aluminum Cement (HAC). This specialized lining offers superior resistance to chemical attack, particularly from sulfates, chlorides, and acidic waters, ensuring long-term hydraulic efficiency and preserving water quality by preventing internal corrosion.
Externally, the pipe features a dual-protection coating system. A primary layer of high-purity zinc is metallurgically bonded to the iron substrate. This zinc layer acts as a sacrificial anode, providing active cathodic protection that effectively prevents pitting corrosion. This primary layer is typically sealed with a final coating, such as a bituminous or epoxy finish, which serves as a durable, passive barrier against abrasion and a wide range of aggressive soil conditions.
In summary, this pipe combines the structural benefits of ductile iron with the exceptional chemical resistance of a High Aluminum Cement mortar lining and the proven, active corrosion defense of a zinc-coated exterior. It is the definitive solution for infrastructure projects requiring unparalleled performance and longevity.
