The water supply ductile iron pipes, fire protection ductile iron pipes, drainage ductile iron pipes, and ductile iron pipe fittings produced by the company all comply with the ISO2531-98E standard. They are made of low phosphorus and low sulfur cast iron produced by ironmaking blast furnaces. The ductile iron pipes are cast using the current centrifugal casting and annealing process using a water-cooled metal type centrifugal casting machine. After annealing, socket trimming, hydrostatic testing, inner wall lining cement, cement lining, water milled cement lining, outer wall coating with asphalt paint, asphalt paint baking, socket rust prevention treatment, marking spraying, and packaging, the steel bars and iron bones have high elongation and corrosion resistance. The price interface form of ductile iron pipes is T-shaped, with standard wall thickness grades of K9, 10 or higher, and a standard effective length of 6 meters.
All ductile iron pipes in the company are produced in accordance with the quality management system, and the product quality has reached the standard. For many years, the company has aimed to build a well-known brand and has won unanimous praise from a large number of users with reasonable prices, good reputation, a sound quality assurance system, and a product after-sales tracking service system.
