Product description
For sizes below DN300, high-pressure molding and resin sand core casting are employed, while sizes above DN300 are produced using lost foam vacuum casting. The advanced wire feeding nodularization process, combined with rational and advanced production techniques, ensures excellent surface quality, high dimensional accuracy, and superior overall mechanical performance.
Customer challenge
While traditional steel pipes offer high strength, their corrosion resistance is poor, making them prone to rust. This necessitates frequent maintenance and replacement, resulting in a shorter service life.
Extended Service Life of Pipelines
Traditional welding methods often present challenges during construction. Welding requires significant labor and time, and the quality of the weld is heavily dependent on the skill level of the operator, leading to potential issues with substandard welding quality.

The interior walls are coated with anti-corrosion materials such as cement mortar, while the exterior walls are protected by zinc spraying and additional anti-corrosion coatings (e.g., zinc spraying + asphalt paint coating, epoxy coal tar coating, etc.). These measures provide excellent corrosion resistance, ensuring long-term durability and reliability.
Ductile iron pipes are the primary conveyance pipelines in water supply and drainage systems. They are capable of carrying various fluid media, and their stable performance and reliable connection methods ensure smooth and efficient transportation of fluids within the pipeline.
Value advantage
