The invention relates to an anti-vibration plug for machining tubes and to a method for placing said plug inside a tube, wherein the plug comprises a central body (2) with arms (3) that open radially outwards intended to come into contact with the inside of the tube (1), a blocking screen (4) being arranged between the central body (2) and the arms (3), which blocks the inside of the tube (1) in the open position of the arms (3), whereas the central body (2) has an axial hole (5) wherein there is housed a piston (6) which movably acts on a peripheral part (8) which surrounds the central body (2) and generates the movement of the arms (3), the peripheral part (8) being subjected to a pushing force exerted by an elastic element (10) in the opposite direction to that in which the piston (6) pushes. |
