Ako sa vyrábajú rúry z tvárnej liatiny? Slovensko

Have you ever been curious about the source of the pipes that bring the water to our homes? Ductile iron pipes play a huge role in this regard and are manufactured in specific type. Company Runhai: Ductile Iron Pipe Manufacturer. So, how are those pipes made and what makes them so unique? 

The Manufacturing Process of Ductile Iron Pipes

Trade name for pipes manufactured from iron (and other ductile materials) to provide additional flexibility and strength compared to standard cast iron pipes. These rúrka z tvárnej liatiny dn100 are cast, which is when the pipe is fabricated before being installed. Runhai melts scrap iron in a large furnace. This furnace is extremely hot, and it contributes to the melting of the iron into a liquid state. Once the iron is sufficiently melted, it is poured into a crucible known as a ladle. Next, the ladle is gently transferred to a part of the process called the casting machine. 

What Are The Specialties Of Ductile Iron Pipes? 

The unique nature of ductile iron pipes lies in their special materials. Besides iron, they also come with additional elements, especially magnesium and cerium. This gives the 2-palcová rúrka z tvárnej liatiny tremendous strength and flexibility compared to ordinary CI pipes. It means that they are unlikely to break or even bend, and there will be no risk of them breaking even under sustained pressure. That's a big deal because that means we can keep our water nice and clean but also flowy. 

How Ductile Iron Pipes are Made? 

Once the liquid iron is within the casting machine, it is poured into a pipe-shaped mold. The mold, which is composed of sand and resin, allows the pipe material to retain its shape when cool and hardened. The combination of sand and resin is utilized in making the casting mould which can withstand hot melted iron. Afterwards the iron is cooled and the pipe is cut up in the appropriate lengths, whereby an excessive metal that does not need is cut away. 

After the pipe is cut to temp, it is then sent to another process known as annealing. Through this step, the pipe is heated to a high temperature and allowed to cool slowly. This gradual cooling is significant because it enhances the metal's strength and ductility. This makes the pipe stronger under temperature and pressure so this pipe has the lesser chances of breaking. 

Machines And Techniques– Used In Pipe Manufacture

The pipework is put up by using technology and machinery. The melting of iron, dredging, is carried out by using large-furnaces to sustain the burning temperature of steel, and because of this, it is reasonable to combine the production process with foundry operations. The molten iron is poured into sand and resin molds that are probably going to be used to cast the pipes by the casting machines. 

After they are completed, the pipes are transferred to another plant for finishing treatments. Here, the pipes do not need to be painted to ensure top quality of the products, but special processes are required. For instance, shot blasting is a technology that is used to remove foreign substances that have deposited on the pipe’s outer surface. Cement is also post-lined onto the pipes to prevent the internal part of the pipe from rust and other forms of corrosion. This liner is rather critical as it aids in the prevention of water pollution in the pipes. 

In conclusion, the process of manufacturing ductile iron pipe is a complex procedure that entails many stages. All the stages including iron melting, pipe casting and pipe finishing require a high degree of precision. Here, Runhai is the company who make sure we get good and clean pipe lines so that we get lines of safe water every day. This also helps us to acquire water and ensures that all the pipes installed in the house are functional and in good condition. It also gives us an insight of how rúrka z tvárnej liatiny are manufactured and the effort placed in the transfer of water to our taps.
