Mechanical Steel Tube is one of the most commonly used types of seamless steel tubes. The seamless steel pipe has a hollow section and no welds from beginning to end. Compared with solid steel such as round steel, seamless steel pipe is lighter in flexural and torsional strength. It is a kind of economical cross-section steel, which is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, bicycle frames and Steel scaffolding used in building construction, etc.
