Due to the high temperature resistance of 2520 high-temperature stainless steel pipe, it is widely used in high-temperature environments, such as furnaces, heat pipes, boilers, heat exchangers and other fields. The following will be introduced in detail from the characteristics, application scenarios, production process and future development of 2520 high-temperature resistant stainless steel pipe.
1. Characteristics of 2520 high-temperature resistant stainless steel pipe.
2520 high-temperature stainless steel pipe is a high-alloy austenitic stainless steel seamless steel pipe, the main components are chromium, nickel, titanium, niobium and other elements. The steel pipe has good resistance to high temperature oxidation, corrosion and creep resistance, and can maintain excellent mechanical properties at higher temperatures, with a long service life. Its excellent high-temperature resistance is mainly due to the addition of metallic elements such as titanium and niobium, which can stabilize the microstructure of steel and improve its resistance to high-temperature oxidation.
2. Application scenarios of 2520 high-temperature resistant stainless steel pipes.
Because 2520 high-temperature resistant stainless steel pipe has excellent high-temperature resistance and mechanical properties, it is widely used in equipment manufacturing in various high-temperature environments. Specific application scenarios include:
1.Furnace: It is used to manufacture various industrial furnaces, such as oil refinery heating furnaces, steel mill rolling heating furnaces, etc.
2.Thermal pipeline: used to manufacture high-temperature steam pipes, such as high-pressure superheater pipes in the utilization system of flue gas waste heat in thermal power plants.
3.Boiler: High-temperature superheater piping and main steam piping used in the manufacture of high-pressure boilers to extend the service life of the boiler and ensure its safe operation.
4.Heat exchanger: used to manufacture various high-temperature heat exchangers, such as heat exchangers and condensers in oil refineries.
3. Production process of 2520 high-temperature resistant stainless steel pipe.
The production process of 2520 high-temperature resistant stainless steel pipe mainly includes smelting, rolling and annealing. In the smelting process, high-purity raw materials are used, and processes such as vacuum induction melting and electroslag remelting are carried out to ensure the purity of the steel and the uniform distribution of alloying elements. In the rolling process, it is necessary to adopt precise control rolling technology and special rolling process parameters to ensure the dimensional accuracy and mechanical properties of the steel pipe. In the annealing process, a high-temperature annealing process is required to eliminate the internal stress generated during the rolling process and improve the plasticity and toughness of the steel pipe.
Fourth, the future development of 2520 high-temperature resistant stainless steel pipe.
With the continuous development of industrial technology and the improvement of environmental protection requirements, the requirements for materials in equipment manufacturing in high-temperature environments are getting higher and higher. Therefore, the demand for 2520 high-temperature stainless steel pipes will continue to increase in the future. At the same time, with the continuous improvement of the production process and the emergence of new materials, the performance of stainless steel pipes will also be further improved. In the future, the application field of 2520 high-temperature stainless steel pipe will be further expanded, and make greater contributions to the development of industrial production and environmental protection.
