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.

Wall thickness
The wall thickness of the tubes shall be in the range of 1.2 - 6.0mm as required. typically as follows:
Thickness in mm | Tolerance in mm |
1.5 to 2.0 | ± 0.15 |
>2.0 to 2.5 | ± 0.18 |
>2.5 to 4.0 | ± 0.20 |
>4.0 to 6.0 | ± 0.28 |
Mechanical Steel Tube industrial applications-from bearings to cylinders and gears-toughness is an essential function. Oil and gas exploration is another common use of seamless mechanical tubing, and its durability and component life are vital below the surface.Special products include aircraft, anti-friction bearings, artillery steel, missiles and steel with high lateral mechanical properties.
