机械加工用无缝钢管是最为常用的无缝钢管种类之一。无缝钢管具有中空截面，

Seamless steel pipe for machining is one of the most commonly used types of seamless steel pipe. 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.

Seamless steel pipe for machining is one of the most commonly used seamless steel pipe types. Seamless steel pipes have a hollow cross-section with no welds from start to finish. Seamless steel pipe compared with solid steel such as round steel, when the same strength of anti-bending, light weight, is an economic cross-sectional steel, widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, bicycle racks and steel scaffolding used in construction.
