Considering replacing your plumbing, or upgrading your sewer lines? Not sure what kind of pipe to use? In certain situations, there are many benefits of ductile iron pipes that you can gain for your property. While ductile iron pipes are normally used for transporting potable water, they can also be the material of choice for home plumbing and sewage systems. Read on to learn more!
One of the benefits of using ductile iron is that these pipes can provide well over 100 years of high-quality performance. There are ductile iron pipes all over the world that are still in service even after 150 years. One of the biggest examples of ductile iron pipe&#;s longevity can be found in the fountains of Versailles, France &#; they were used by the palace for over 300 years before needing to be replaced and repaired.
What makes ductile iron so long-lasting? The answer lies in ductile iron&#;s ability to avoid common metal weakness and degradation over time. Most materials (such as cast iron or PVC) suffer from structural issues known as &#;creep&#; and &#;stress regression.&#; These can cause materials to degrade and lose strength over time. Creep and stress regression are also worsened by constant changes in temperature, pressure, and other performance factors.
How does ductile iron manage to overcome the constant changes in temperature, pressure, and environment? It can do so due to its higher levels of ductility. Ductility refers to a metal&#;s ability to be drawn, extruded, and deformed without becoming damaged. It is a good indicator of how malleable and formable the metal is.
This type of pipe gets its name from how easily formed the iron alloys are. This means that ductile iron pipes are quickly manufactured, and it is likely that each pipe would be made without any fractures, dents, or similar defects. It also means it can withstand additional stress and pressure without breaking or fracturing either.
Despite ductile iron pipes having similar chemical properties to cast iron pipes, ductile iron has superior strength and resistance. This comes from the significant casting requirements, metallurgical processes, and improved quality control in its manufacturing.
When creating ductile iron, there is an improved manufacturing process that changes the structure of the graphite in the iron. In cast iron, this graphite would be in a flake-like shape. In ductile iron, this graphite is changed into a spheroidal or nodular shape. This is achieved by adding an inoculant (usually magnesium) into molten iron during manufacture.
Due to this new graphite structure, ductile iron has almost twice the strength of cast iron. This is shown by the improved results of ductile iron in tensile, beam, ring bending, and bursting tests. Additionally, ductile iron&#;s ability to withstand impact and elongation is many times greater than cast iron.
Ductile iron pipes are much lighter and easier to lay into sewer lines than most other pipes &#; such as grey iron or cast iron pipes. Additionally, they require no additional treatment or encasements to be laid directly against soils.
However, you can choose to use polyethylene encasements to enhance the pipe&#;s corrosion resistance against moisture and soils. This process is also economical &#; the pipes are simply wrapped with sheets or tubes before installation, and the pipes remain easy to carry and lay into sewer systems.
Additionally, on the off chance that a leak occurs, repairs can be done quite easily. A majority of the time, leaks can be addressed without needing to replace whole sections of the ductile iron pipe. Instead, repairs can be done in-place using resin repair sleeves to effectively block all leaks.
Joints for ductile iron pipes are also much more simple than those used for other piping options. This means that joints are easier to install and repair for ductile iron pipes. Additionally, these joints are capable of more deflection than other pipe joints. Ductile iron pipe joints can be deflected by up to 5 degrees, while other pipes are often unable to be deflected at the joints. This means that ductile iron pipes reduce the need for pipe bending, which reduces the chances of stressing or fracturing the metal.
Ductile iron pipes have larger inside diameters compared to other pipe options. This means that water systems can achieve maximum water flows through these pipes. As a result, your pumping mechanisms need to work less to pump water throughout your whole plumbing system. In the end, you will experience lower pumping costs due to the ductile iron pipe&#;s larger inside diameter. As a plus, it also has better burst strength, which helps it resist high-pressure water flows and sudden pressure surges.
Ductile iron is fabricated using recycled steel and iron scrap metals. These recycled materials make up about 95% of the ductile iron composition. The high level of recycled components also makes ductile iron pipes 100% recyclable itself. What this means is that the costs of ordering and manufacturing ductile iron are reduced, and even if your pipes get damaged, you can have them recycled into new pipes for your home.

7 Benefits of Using Ductile Iron Pipes
Apr. 09,
Ductile Iron which is also known by the name of the Spheroidal graphite iron or Nodular Cast Iron was invented in . This material retains the corrosion resistance of cast iron but has more than double tensile strength, i.e, Cast Iron -180 MPa (min), Ductile Iron &#; 420 MPa (min). The main difference between cast iron and ductile iron is characterised by the shape of the graphite in the microstructure of the metal. In the case of cast iron, graphite is present in sheet-like flakes, which makes the cast iron brittle, but in the case of ductile iron, the graphite takes the shape of spherical nodules, which increases the tensile strength and makes the ductile iron-strong and impact resistant.
Considered the most preferred pipe material for water supply and pressure sewerage application, ductile iron pipe and ductile iron fittings are used all over the world. They offer higher tensile strength and diametral stiffness than Mild Steel and retain the inherent corrosion resistance of cast iron. Substantial benefits can be obtained from Ductile Iron Pipes in terms of pressure bearing ability, impact resistance and capacity to sustain external static/dynamic loading. Modern DI Pipes are made to last over 100 years, and is an environmentally preferable product due to their recycled content, energy savings, while in service, their durability, their own recyclability and the commitment of the pipe industry.
According to reports, the projected service life for modern ductile iron pipe fittings is at least 105 years and due to its longevity, there is more iron pipe in service today than any other pipe material.
Made up of around 98% recycled content, they are themselves a 100% recyclable material.
Significant energy savings are obtained during the pipe&#;s lifetime in service due to lower costs from increased flow capacity.
These pipes are extremely strong and can easily withstand the most severe conditions ranging from high-pressure applications to heavy earth and traffic loads, to unstable soil conditions.
They are resistant to corrosion in most soils.
Ductile Iron Pipes and Fittings is the pipe of choice to protect against surges and increased pressure loadings because of their strength, durability, and conservative design.
The installation is very much easy&#;it is safe for workers as they can cut and tap these pipes on site.
It is rugged and resists damage during handling and installation. Due to their metallic nature, these pipes can be easily located underground with conventional pipe locators.
Ductile Iron pipes normally possess thicker pipe walls and are generally stiffer than steel pipes. As such, it relies less on side fill soils to support external loads so it is necessary to achieve highly-compacted soils for ductile iron pipes for sustaining external loads.
For black iron pipes, owing to less stiffness associated with thinner pipe walls, it relies heavily on the stiffness of backfill soils in resisting external loads. So to enhance the external load carrying capacity of steel pipes, the most convenient methods are to improve the quality of backfill materials and to increase the level of soil compaction.
So it can be concluded that, for various piping projects, ductile iron is the most beneficial choice which may offer high performance for a long time and can also help to save on other additional costs. Are you looking for ductile iron pipes and fittings suppliers in China? Welcome to contact us.
