Seamless steel pipe with hollow section is extensively used for conveying fluid pipelines, such as oil, natural gas, gas, water, and solid materials. Compared to solid steel, it offers light weight with equivalent bending and torsional strength, making it an economic cross-section steel. It is widely applied in structural and mechanical parts, such as petroleum drill pipes, auto transmission shafts, bicycle frames, and construction scaffolding.
