[0002] Seamless steel pipes have hollow cross-sections and are widely used as pipelines for conveying fluids, such as pipelines for conveying oil, natural gas, coal gas, water and some solid materials. Compared with solid steels such as round steel, steel pipes are lighter in weight when the bending and torsional strengths are the same. They are an economical cross-section steel and are widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, bicycle frames, and steel scaffolding used in construction. Using steel pipes to manufacture annular parts can improve material utilization, simplify manufacturing processes, save materials and processing time, and steel pipes have been widely used.
