Abstract:
Pipe cast iron water supply pipe is made by high-speed centrifugal casting of cast iron liquid with nodule agent. Ductile iron pipe has the characteristics of iron nature, steel performance, good ductility convenient installation, good corrosion resistance. Mainly used for transporting water, gas and oil in municipal, industrial and mining enterprise. Nodular cast iron pipe is the first choice for water supply pipeline with high cost performance. Ductile cast iron have a diameter of 80 to 2200mm and length of 5m,6m and 8m compared to grey cast iron pipe ductile cast iron pipe has the advantages of high strength, good toughness, thin wall and lower metal consumption and high pressure resistance. one of the advantage of cast iron pipes is their longevity With proper installation and maintenance they can last for decades, even up to a hundred years. They are also known for their sound dampening properties. which help in reducing noise caused by flowing water. However, cast iron pipes have disadvantages. They are heavy, making them difficult to transport and install. They are also prone to rusting and corrosion with time, particularly if not properly maintained. Furthermore, cast iron pipes have a smooth interior that can allow sediment and other material to accumulate, resulting in blockages and reduced flow. Corrosion of water pipelines is a serious issue that affects everyone. It's also a tough issue.. The complexity of understanding this topic stems from the diversity of materials used, the wide range in water chemistry that is considered potable, the variety of methods for mitigating corrosion, and the interplay of these factors As a result, it is difficult to develop specific guidelines that are applicable to all situations, materials, and water. These factors affect both the dissolution rate and the stability of the protective.
