Cast iron pipe is pipe made predominantly from gray cast iron. It was historically used as a pressure pipe for transmission of water, gas and sewage, and as a water drainage pipe during the 17th, 18th, 19th and 20th centuries.
In many modern applications, cast iron pipe has been replaced by ductile iron pipe, but this newer product is still often loosely referred to by the older historical name.
Cast iron fittings, especially ductile iron pipes, are widely used in various scenarios due to their excellent performance characteristics. The following are the main scenarios where cast iron fittings are applicable:
1. Urban water supply and drainage system
Water supply system : Ductile iron pipes have become the preferred material for urban water supply pipeline systems due to their excellent corrosion resistance, compressive strength, and low water transmission resistance. It can ensure the safety of water quality and stable flow rate, while the inner wall is smooth and not easy to scale, which helps to improve the quality of water supply.
Drainage System : In the drainage system, ductile iron pipes can withstand the impact of high-pressure water flow and the erosion of corrosive substances, and are widely used in rainwater and sewage discharge systems to ensure the smooth operation of the drainage system.
2. Gas pipeline system
The application of ductile iron pipes in gas pipeline systems is becoming increasingly widespread. Its corrosion resistance can resist corrosive substances in gas, its compressive strength can withstand the pressure inside and outside the pipeline, and its sealing performance ensures the safe transportation of gas, ensuring the safety and reliability of gas supply.
3. Industrial piping system
In the industrial field, ductile iron pipes also have wide application value. In industries such as chemical, metallurgical, petroleum, and pharmaceutical, ductile iron pipes can meet the needs of various complex working conditions, such as transporting various fluids and gases. Its excellent corrosion resistance, high pressure resistance, high temperature resistance, as well as good rigidity and toughness, enable it to work stably in various industrial production environments.
4. Bridge and Road Engineering
In bridge and road engineering, ductile iron pipes are commonly used in drainage systems. Due to its high strength and impact resistance, it can withstand the heavy pressure of vehicles and pedestrians, and its smooth interior is not easily blocked, making it an ideal choice for drainage systems in bridge and road engineering.
5.Water supply and fire protection system of buildings
Ductile iron pipes are also widely used in the water supply and fire protection systems of buildings. The water supply system needs to ensure the safety of water quality and stable flow, while the fire protection system needs to supply water quickly and effectively in emergency situations. The excellent performance of ductile iron pipes enables them to meet these requirements, providing reliable support for the water supply and fire protection systems of buildings.
6. Agricultural irrigation system
In agricultural irrigation systems, ductile iron pipes also play an important role. The agricultural irrigation system needs to transport a large amount of water resources to farmland and also needs to withstand various complex environmental factors. The corrosion resistance, compression resistance, and impact resistance of ductile iron pipes enable them to meet the needs of agricultural irrigation systems. At the same time, their smooth inner walls and resistance to scaling also help improve the quality and flow rate of irrigation water.
In summary, cast iron fittings, especially ductile iron pipes, play an important role in modern industry and social life due to their excellent performance and wide application fields. Whether in urban water supply and drainage, gas transmission, industrial production, or agricultural irrigation, the presence of ductile iron pipes can be seen.
