Chalco streamlined aluminum tube production and processing

While traditional streamlined tubing is produced through a cold-drawn process in random lengths (typically 10 to 17 feet), Chalco’s high-performance tubing is roll-formed, where round tubing is passed through a series of progressive rollers and dies. This process results in a more consistent and repeatable shape.

Although cold drawing is an effective way to produce streamlined tubes, roll-formed tubes have tighter tolerances, avoid the bending problems common in cold-drawn tubes, and produce a straighter product. In addition, roll-forming allows the wall thickness of the parent round tube to be maintained, providing more wall thickness options.

Extruded flowline tube

Heating the material at high temperature and extruding it into a tube has the advantage of manufacturing seamless streamlined tubes, ensuring uniform structure, high strength and good compression resistance of the tube, which is suitable for high-strength applications.

Cold drawn streamline tube

By stretching the tube at room temperature, the tube dimensions are further precisely controlled in the mold, further improving its mechanical properties. With higher dimensional accuracy and surface finish, it is suitable for applications requiring tight tolerances.

Roller-formed streamlined tube

The tube material is processed into a streamlined shape through a rolling process. It can maintain the consistency of tube wall thickness, is suitable for medium and large-sized streamlined tubes, and has high production efficiency.

Welding flow line tube

Welding technology can connect plates or pipes into customized streamlined structures, which are suitable for large diameters or special shapes, have low production costs, and can flexibly meet non-standard specification requirements.
