The history and price of ductile iron pipes date back to their use of these pipes as pressure corrugated pipes to transport water, gas, and sewage and to drain water from pipes. Many suppliers work on this product per meter and because These pipes are basically gray cast iron, they are usually used uncoated, although coatings reduce the risk of corrosion in these pipes and improve hydraulics. The advantages of cast iron pipes are: Thicker than ductile or steel pipe wall Corrosion rate similar to a ductile iron pipe and galvanized steel pipe Most pipes built after 1950 have a cement mortar coating.
They have no elastic behavior and their mechanical strength is low. Cast iron pipes are iron-carbon alloy pipes with a carbon content of more than 2%. They are widely used in water supply, sewage, and gas pipeline networks. Return. The structure of these types of pipes is mainly made of graphite iron or gray iron, which is basically the same as gray iron, and mostly uncoated in the beginning. Later, to improve the hydraulic properties and increase resistance to erosion and corrosion, the coating operation of the inner and outer walls of the pipeline was added during production. There are different types of cast iron pipes on the market, each with its own characteristics and different uses based on those characteristics. Gray cast iron and white cast iron are the two most commonly used cast iron alloy pipes.

ductile iron pipe price per meter
Ductile iron pipes are priced per meter and it can be said that these pipes, as the name suggests, are made of ductile iron and have unique properties for transporting water under pressure and for transportable water distribution. Among the advantages of using ductile iron pipes, the following points can be mentioned: High resistance to expansion pressure and strong impact Low pumping costs Easy to install and test these tubes Anti-blasting and ground movement Can work continuously in hydraulic flow Sizes vary from 50 to 2000 
Cast iron pipes are generally manufactured using a pit, horizontal or centrifugal methods. In the vertical pit method, the mold is made by tamping sand around the pattern and drying the mold in an oven. Put the core in the mold and pour molten iron between the core and the mold. In the horizontal method, a device is used to move sand around in a horizontal shape with a mandrel. The molten iron is poured from the manufactured multi-layer spoon into a mold so that the iron is collected from below, which eliminates the ingress of impurities. In the centrifugal method, sand-coated molds are used, which are placed horizontally in a centrifugal casting machine. As the mold rotates, a precise amount of molten iron is introduced, which distributes into the mold walls under the influence of the speed of rotation, producing tubes in seconds. Cast iron pipes have advantages such as damaged walls, lack of elastic behavior, low mechanical strength, and ISO certification compared to steel and ductile pipes. 
In addition, their corrosion rates are similar to galvanized steel pipes and ductile pipes. Cast iron pipes, while having many uses in various projects, are inexpensive to install and easy to supply and install. Other benefits of using cast iron pipes include: Reduced sound transmission due to thickness The price and cost are lower than iron pipes Durability and high performance Diversity of connections and adaptability High resistance and strength to pressure applied to external walls Less wear and tear than metal pipes Blockages in pipes can be removed using compressed air The versatility of the project Abundance and availability

Many customers ask the supplier for the installation of ductile iron pipes as well. If you look at them you can see how they function when it comes to the installation part. How to install cast iron pipes The heads of the cast iron pipes are designed to be male and female and placed on top of each other. These tubes are available in two types of ball ends and two types of flat ends. Typically, the installation of ductile iron pipes is done with hemp and lead, while the installation of flat iron pipes uses special washers and fasteners. Always try to get the size of the pipe and its location right at the start of the work and measure the conditions at that location correctly. This way you can choose the standard size to buy the connection you want.

ductile iron price per meter ductile iron pipes are cast iron products that are widely used in plumbing and ventilation systems. The price of these products is calculated per meter. There are many varieties of these pipes, which are related to their size, shape, and alloy type, and are generally divided into two types: ball head and flat head. Today, in various industries, cast iron fittings are widely used for roof or garden waste discharge, sewer pipes, and residential ventilation.

ductile iron price supplier
There are many suppliers of steel products in the market and they have different prices as well. Ductile iron is just one of the products that need a good supplier to support and give the best quality product because if the product is just a little under the quality they need it may break or have fractures. Ductile iron or ductile iron is a special form of cast iron that is transformed into a material of infinite strength by adding magnesium and alloys to a metal with high electrical resistance and resistance to brittleness. The difference between ductile iron and gray iron: The addition of magnesium to cast iron melts with flake graphite (gray iron) results in the transformation of these materials into spherical graphite, the spherical structure of these graphite increases the tensile strength and also increases the bearing capacity Weight ratio Gives three times the strength and durability of this cast iron compared to gray cast iron. Advantages of ductile iron: Compared to gray cast iron, the weight-to-strength ratio of ductile iron allows the production of parts with a weight reduction of approximately 50% and higher compressive strength. 
The inherent high resistance of ductile iron not only minimizes the risk of valve failure but also reduces the likelihood of breakage during shipping and handling. In a market where all products are expected to reduce manual handling risks and reduce shipping costs, weight reduction of manufactured components with greater efficiency during installation and use is considered a key and important feature. Anti-theft of the valve: a) Ductile iron's high impact resistance and brittleness prevent the hinge part of the door and the valve from breaking, thieves cannot separate the door and the coil (frame) and steal it. b) In addition, these valves have hidden hinges that are welded into the assembly and not closed with bolts and nuts like the old ones. c) The valve coil is also designed so that it is completely fixed in the concrete and cannot be separated from asphalt and concrete (net spiral). Presence of gaskets in valves: The spool seats of the above ductile iron valves are all equipped with gaskets complying with EPDM standards to prevent noise pollution due to vehicle movement and its impact on the doors of the spool (frame). 
iron price supplier
In every industry, the ex-work price or the price of the supplier is the best price because it’s the price of the factory. Iron and iron products are not exceptions as well. Most of the ore from which iron is extracted is in the form of iron oxides, such as magnetite or hematite, with 2 to 20% impurities (such as silicates and aluminates). These impurities are separated from the iron in the furnace and come out as slag. Refined and concentrated ore enters the furnace in powdered or granulated form. The most suitable particle size is between 6 and 25 mm. Today, natural iron sulfide (pyrite) is not used for iron extraction but is mostly used for sulfuric acid. Iron minerals are divided into four parts: oxide minerals carbonate minerals sulfide minerals silicate minerals 
The main iron minerals used in the iron and steel industry are 72% iron magnetite Fe3O4 and 70% iron hematite Fe2O3, which can be extracted from the mine. The size and type of iron ore granulation are very important to use the required quality steel in the blast furnace, in order to fully recover the iron ore, the minimum particle size used in the blast furnace should be 10mm. Every day, 2000 tons of iron ore are pelletized by three vibrating screening machines in a special place, and then sent to the sintering section and blast furnace section. There are two ways of producing iron in different countries of the world: blast furnace (converter) Direct regeneration or electric furnace For iron production, the specific conditions of the individual countries also depend on the type of raw material and the available energy. In countries with high-quality coal resources, the blast furnace method is cost-effective, and in countries with abundant natural gas resources, the direct regeneration method is cost-effective. blast furnace iron production 
The production of iron using traditional methods has a long history. The first ovens were produced in England in 1600 AD, and from 1800 AD were they used commercially by heating the incoming air. For steel production, after the iron ore is extracted from the mine using the traditional blast furnace method, it is crushed and screened to the desired size and transferred to the iron ore stockpile. After crushing, the iron ore and some coke fines are first transferred to the coke department and from there into the blast furnace. The blast furnace is charged in the form of layers of iron ore, coke and limestone, and hot air is blown into the furnace through a blower pipe. Therefore, while flowing in the furnace, the regenerated iron ore melts due to high temperature and accumulates in the lower part of the furnace. The molten iron is discharged from the furnace after a certain period of time and then transferred to the converter together with scrap iron. The molten pig iron in the converter achieves the required temperature and composition by blowing oxygen.
