For the manufacture of tubes with longitudinal welding, we use the best raw material available in the market. The main process is the transformation of materials, for which we have several bending machines, each one of these is used depending on the material.
We use Submerged Arc Welding (SAW), and it is carried out by means of a column, which allows the parameters to be constant during the entire process, and therefore an even and perfect seam is achieved.

Dimensional specifications

For this type of tube, the diameters are from 170 mm to 2000 mm, and the thickness is from 3mm to 12mm, besides the longitude may reach up to 14 m. In order to obtain a greater handling possibility, we also have packaging machines for packing tubes.

Bridge type filter

The production of bridge type filter tubes, that is to say, subtype tubes with longitudinal welding, practically uses an identical process as aforementioned.
