Ductile Iron Pipe, manufactured via centrifugal casting and annealing, offers exceptional strength, corrosion resistance, and durability for global water, sewage, and industrial projects. Compliant with EN545/EN598 standards (C25/C30/C40 pressure classes), it features a nodular graphite structure that ensures high impact resistance and a 100+ year service life, minimizing maintenance costs. The pipe’s precision-engineered joints (e.g., push-fit or flanged) simplify installation, reducing labor and time. Coated with zinc, epoxy, or polyethylene, it withstands harsh soils, aggressive waters, and varying temperatures. Available in diameters from 80mm to 2,000mm, it adapts to diverse project needs—from municipal networks to industrial plants. Choosing this pipe guarantees reliability, safety, and long-term value, making it a trusted solution for clients seeking robust, cost-efficient, and sustainable piping systems worldwide.

Product line

The ductile iron used to manufacture the pipe is characterized by the spheroidal or nodular nature of the graphite within the iron. Typically, the pipe is manufactured using centrifugal casting in metal or resin lined moulds. Protective internal linings and external coatings are often applied to ductile iron pipes to inhibit corrosion: the standard internal lining is cement mortar and standard external coatings include bonded zinc, asphalt or water-based paint. In highly corrosive environments loose polyethylene sleeving (LPS) to encase the pipe may also be used.

Product testing

In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.

Product packaging

Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
