Precision Seamless Steel Tube: Delving into the Manufacturing Process

2.1 Initial Steps: Piercing and Extrusion

The manufacturing process of precision seamless steel tube commences with piercing, where a hole is created in a solid round billet to form a tube. This tube then undergoes either extrusion or rotary piercing, shaping the tube and beginning the journey toward precision.

2.2 Mid-Process: Elongation and Reducing

Subsequently, the tube experiences elongation, a process where its diameter is reduced while its length is increased. The reducing stage follows, ensuring that the tube attains the desired diameter and wall thickness, aligning with the specifications required for its intended application.

2.3 Final Stages: Heat Treatment and Cold Working

Post the initial shaping, the tube undergoes heat treatment through annealing, a step pivotal in enhancing its mechanical properties. Following this, the tube is subjected to cold working, involving cold drawing or pilgering, to achieve tighter tolerances and improve dimensional accuracy.

2.4 Completion: Final Processing

The concluding step in the manufacturing process involves final processing, which includes cutting, inspection, and finishing of the tubes. This ensures that the tubes produced by Xuzhou Global Precision Steel Tube Co., Ltd meet the highest quality standards and are ready for deployment in various applications.
