The first steps are coils made of different steel grades, which quality and properties have been tested and recorded.
Coil slitting
In the slitting lines, the coil becomes strip coils.
Once they are properly classified, the coils are mounted in the tube mills.
Forming
The strip is bended by means of forming rolls until the edges are making contact.
Welding
By means of High Frequency welding both edges are joined.
Sizing
Those rolls give shape and accurate dimensions to the tube.
Cutting
The cutoff cuts the tube to the desired length.
The tube bundles are carried to the store ready for delivery.
Threading
The pipes for conduction may be threaded.
Cut to fix length
For tubes unded 4 m.
Hot galvanizing
It can be done upon request.
Packaging
The tubes are packed in bundles and label for its storage.
