Application of carbon steel pipes in boiler field

As the core equipment in industrial production, the selection of structural materials is crucial. Among them, carbon steel pipes (CS pipe) occupy a pivotal position in boiler manufacturing due to their unique physical and chemical properties.

The application of carbon steel pipes in boiler field is mainly reflected in the following aspects:

1. Heating surface: Carbon steel pipes are often used for the heating surface of boilers, such as water-cooled walls, superheaters and other parts. These components are directly subjected to the erosion of high-temperature flue gas, and the high temperature resistance of carbon steel pipes makes them perform well in these positions.

2. Support structure: Carbon steel pipes are also used to construct the support structure of the boiler to ensure the stable operation of the boiler. Its good strength and toughness make carbon steel pipes perform well when bearing the weight of the boiler and vibration during operation.

3. Connecting pipes: In the boiler system, carbon steel pipes are also used to connect various components, such as pipes for conveying steam or water (boiler tube). Its excellent pressure resistance ensures the stable operation of the system.

Specific application examples of carbon steel pipes in boilers include:

1. Water-cooled wall: The water-cooled wall is an important part of the boiler. The water-cooled wall made of carbon steel pipes can effectively absorb the radiant heat in the furnace and protect the furnace wall from high temperature damage.
2. Superheater: The superheater is used to heat saturated steam into superheated steam. The superheater made of carbon steel pipes can work stably in a high temperature environment to ensure the quality of steam.
3. Economizer: The economizer is used to preheat the cold water entering the boiler. The corrosion resistance and high temperature resistance of carbon steel pipes make it perform well in this process.

The advantages of carbon steel pipes in boilers include:

1. Material characteristics: Carbon steel pipes, mainly composed of carbon and iron elements, are mainly made into tubular shapes through two production processes: seamless and welding. This material has good strength and toughness, especially carbon steel seamless pipes, which can withstand the high temperature and high pressure environment when the boiler is working.

2. High temperature resistance: Carbon steel pipes can maintain stable physical and chemical properties in high temperature environments, are not easy to deform or damage, and are suitable for use in high temperature environments such as boilers.
‌

3. Corrosion resistance: Through special surface treatment, carbon steel pipes can effectively resist the corrosion of gases and moisture generated by fuel combustion to materials, extending the service life of boilers. ‌

4. Cost-effectiveness: The manufacturing cost of carbon steel pipes is relatively low, making them more economical in boiler manufacturing.

Conclusion:
The application of carbon steel pipes in boilers is mainly reflected in the following aspects: First, as the heating surface of the boiler, such as water-cooled walls, superheaters, etc., directly bear the scouring of high-temperature flue gas; second, it is used to build the support structure of the boiler to ensure the stable operation of the boiler; third, as a connecting pipe, it transports steam or water required for the operation of the boiler.

In short, carbon steel pipes for boilers play an important role in the boiler industry with their excellent performance. In the future, with the advancement of science and technology and the improvement of technology, the performance of carbon steel pipes will be further improved, bringing more possibilities for boiler manufacturing.
