Product Description
Carbon Steel Pipe

Seamless steel pipe features a hollow section and is extensively used for conveying fluid pipelines, including oil, natural gas, gas, water, and various solid materials. Compared to solid steel like round bars, seamless pipes offer lighter weight with high torsional strength, making them an economical choice for structural and mechanical components such as drill pipes, automotive shafts, and construction scaffolding.
