Applications of the seamless aluminum tube

· Aerospace: aircraft fuel lines, engine conduits and fluid transfer, etc.
· Automotive: cooling systems, hydraulic systems and fuel delivery systems, etc
· Outdoor equipment: fishing rods, tent poles, golf club, bicycle frame, etc.
· Oil tanker pipeline
· Geophone sensor
. etc..

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

The Differences between Seamless Tube and Structural Tube (Welded 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.
