What is the Difference Between Ductile Iron Pipe and Seamless Steel Pipe?

As a Ductile Iron Pipe Suppliers, share with you.

Nodular cast iron pipe is a very common municipal water supply pipe, which can be used for municipal drainage and sewage drainage, etc. Anyang Yongtong cast pipe mainly supplies a large number of nodular cast iron pipes. Many people have been interested in nodular cast iron pipes and seamless steel pipes. The difference is not very clear. Let's take a look at how the ductile iron pipe manufacturer distinguishes the ductile iron pipe from the seamless steel pipe.

Ductile Iron Pipe

1. Ductile iron pipes and seamless steel pipes are of different materials. Fire-fighting ductile iron is iron, and No. 20 seamless steel pipe is steel; the production process is different, and the station is promoted. Ductile iron is poured by molten iron, and seamless steel pipe is processed by rolling mills. , The performance indicators are different. Ductile iron generally has a large diameter, a thick tube wall, a brittle texture, and heavier. For promotion forums, seamless steel pipes can be made of very small diameter, thin tube walls, good toughness, and lighter.

2. The tube is cast with cast iron. Cast iron pipes are used for water supply, drainage and gas pipelines, and include straight cast iron pipes and pipe fittings. The labor intensity is small. According to different forging methods, it is divided into continuous cast iron pipe and centrifugal cast iron pipe. Among them, centrifugal cast iron pipe is divided into sand mold and metal mold. According to different materials, it can be divided into gray cast iron pipe and ductile iron pipe.

3. The ductile iron pipe is formed by centrifugal force casting, the pipe wall is dense, the graphite shape is spherical, the matrix is mainly ferrite, the elongation is high, the strength is similar, the performance is similar to the steel pipe, it is flexible, and adapts to sudden forces And the bending strength is greater than that of steel pipes, and the pipe sections are not easy to bend and deform during use. It can withstand larger loads. The material has a corrosion resistance of 35% higher than that of gray cast iron. It does not need anti-corrosion treatment. Its interface is a flexible interface, which is flexible and tortuous, and adapts to uneven foundation subsidence. It is an ideal pipe.
