Advantages of Seamless Aluminum Tubing
No welds, the first choice for pressure vessels
More uniform anodized appearance, especially on heavier wall sections
No welds that could split during forming operations
Improved structural integrity
Applications of Seamless Tubing
Seamless aluminum tubes are usually used for pressure vessels, hydraulic cylinders, compressed gas cylinders, drive shafts, lighting applications and bus conductors.
The Difference between Seamless Tube and Structural Tube (Slit Tube)
● Different tooling: the seamless extrusion tube is extruded over a mandrel utilizing a hollow billet and is the only tubular product recommended for pressure applications. The structural tube is extruded over a bridge or porthole die.
● Seamless extruded tube doesn't have any welding joint, but the structural tube has an indistinguishable weld seam.
● Compared to an extruded seamless tube, a structural tube is more able to use multi-hole dies for smaller diameter sizes to improve productivity and decrease costs.
● There’s a little difference in appearance. For seamless tubing, the seamless tube’s inner and outer walls are smooth and clean-burning or cracking on the surface; The appearance of the slit tube is generally smooth.
