<p>Method for manufacturing sealed metal tubes, where the first end (2) of the tube (1) is placed in a rotor (5) of a grooving machine (4), and the second end (3) in a holding system (6) of said machine, positioning a rotary grooving tool (7) in a desired closed position (9), on the outside of the tube (1). Subsequently sealing means (8) are inserted inside the tube (1) in the desired closed position (9), the rotor (5) of the grooving machine (4) is activated which turns the tube (1), and the grooving tool (7) is actuated against the external surface of the tube (1), which by means of pressure creates a groove (10) reducing the diameter of the tube (1), and fixing the sealing means (8) to the internal surface of the tube (1) by pressure and sealing it.</p> |
