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.

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.
