Ductile iron pipes are formulated with carbon and other elements, making the finished product stronger, tougher and longer-lasting, two to three times longer than traditional steel pipes. The difficulty of producing this type of iron pipe increases exponentially as the diameter increases. The ductile iron pipe that went into production today has a processing and adjustment accuracy of less than 0.1 mm. my country is the only country that can produce ductile iron pipes with a diameter of more than 2.6 meters. How difficult is it to produce large-diameter ductile iron pipes? Let's take a look at the reporter's report.

How difficult is it to produce large-diameter ductile iron pipes? Let's take a look at the reporter's report.

After being cast at a temperature of over 1,300°C, the world's largest ductile iron pipe officially rolled off the production line. At this moment, I was more than ten meters away from it, and I could already feel the rolling heat wave.

The production line next to it casts iron pipes with a diameter of 1.4 meters, which weigh only 3.6 tons, while this large iron pipe with a diameter of 3 meters weighs 15 tons, equivalent to the weight of 10 family cars.

So how big is a 3-meter pipe? Let's take a closer look. After entering, I found that it was as high as a floor, and I couldn't reach the top even if I jumped. Although its diameter is only 2 meters larger than the 1-meter diameter pipe commonly used in water conservancy projects, the total water delivery capacity has increased by more than 20 times. There is no doubt that it will play a greater role in alleviating the uneven distribution of water resources.
