High pressure boiler tubes are mainly used for high-pressure and high-temperature industrial applications, usually in the following fields:Boiler system: High pressure boiler tubes are widely used in thermal power plants, nuclear power plants, and other types of boiler systems. They transport hot water or steam to generate steam power for power generation.Chemical industry: High pressure boiler tubes are used for high-temperature and high-pressure fluid transportation in the chemical industry. They can transport chemicals, petroleum products, natural gas, and other hazardous substances.

In summary, there are some differences between precision steel pipes and ordinary steel pipes in terms of production process, physical properties, and application scope. Precision steel pipes have high process accuracy, physical properties, and dimensional accuracy, making them suitable for fields with high material performance requirements. Ordinary steel pipes are mainly used in general construction, transportation, and support fields. The different application scenarios and requirements determine the characteristics and scope of use of these two types of steel pipes, and suitable steel pipes need to be selected based on specific needs.

Extrusion or rolling: The blank tube is formed into the final shape of a seamless tube by gradually reducing the outer diameter and wall thickness through an extrusion or rolling machine. This step requires a high degree of control to ensure that the size and quality of the pipeline meet the specification requirements.Annealing: Annealing is an important heat treatment step that eliminates residual stress and improves the mechanical properties and toughness of pipelines by annealing them at high temperatures.

Smooth surface: The inner and outer surfaces of high-pressure boiler pipes need to be polished and cleaned to ensure smooth surface and reduce resistance and friction losses. A smooth surface is conducive to the flow of water vapor or other media and reduces fluid friction losses within the pipeline.5. High corrosion resistance: High pressure boiler tubes usually need to work in corrosive media, so they must have good corrosion resistance. Different media have different corrosiveness to pipeline materials, so when selecting materials for high-pressure boiler pipes, it is necessary to make reasonable choices based on specific working conditions. Some corrosion-resistant alloy steels and stainless steels have high corrosion resistance and are suitable for working environments with corrosive media.
