Hot rolled steel is steel that has been roll-pressed at very high temperatures—over 1,700, which is above the recrystallization temperature for most steels. This makes the steel easier to form, and resulting in products that are easier to work with. To process hot rolled steel, manufacturers first start with a large, rectangular length of metal, called a billet. The billet is heated and then sent for pre-processing, where it is flattened into a large roll. From there, it is kept at a high temperature and run through a series of rollers to achieve its finished dimensions. Steel shrinks slightly as it cools. Since hot rolled steel is cooled after processing, there is less control over its final shape, making it less suitable for precision applications. Hot rolled steel is often used in applications where minutely specific dimensions aren't crucial.

1、 High strengthCarbon steel pipes have high strength and can withstand large pressures and temperatures. This makes them have good durability and corrosion resistance when applied to heat exchangers. Due to the good durability of carbon steel pipes, maintenance costs and downtime of the heat exchanger can be reduced, greatly improving the operational efficiency and reliability of the heat exchanger.

2、 Lower costsDue to the mature production process of carbon steel pipes, the production cost is relatively low. Meanwhile, carbon steel pipes have good plasticity and processability, which can meet the needs of various complex shapes and are more suitable for mass production, resulting in lower costs.

3、 Good corrosion resistanceCarbon steel pipes also have good corrosion resistance, especially at low temperatures, which can effectively prevent corrosion and oxidation. This makes carbon steel pipes more suitable for use in harsh environments, such as in the marine and chemical industries.

4、 Widely usedThe excellent performance of carbon steel pipes makes them widely used in industrial production, not only for heat exchangers, but also in nuclear power plants, oil and natural gas transmission pipelines, shipbuilding and other fields. At the same time, carbon steel pipes can also be used as support and connecting components in building and bridge construction.
