Stainless steel seamless pipes are long steel products with a hollow cross-section and no seams around their periphery.
1. Manufacturing Process and Flow of Seamless Pipes:
Smelting > Ingot Casting > Rolling > Sawing > Peeling > Piercing > Annealing > Pickling > Sizing > Cold Drawing > Cutting Heads > Pickling > Storage 
2. Characteristics of Seamless Steel Tubes:
From the above process flow, it is evident that:
I. Thicker wall thickness enhances the product's cost-effectiveness and practicality, while thinner walls significantly increase processing costs;
II. The manufacturing process imposes limitations: generally low precision, including uneven wall thickness, low surface brightness on both inner and outer surfaces, high fixed-length cutting costs, and persistent surface imperfections like pitting and black spots that are difficult to remove;
III. Inspection and reshaping must be performed offline. Consequently, it demonstrates superior performance in high-pressure, high-strength, and mechanical structural applications.
