Abstract
A device for descaling a metallic membrane of a tank for transporting and/or storing gas in liquid form includes: a rail secured to the metallic membrane; a head projecting a laser beam to descale the metallic membrane; a support interposed between the projection head and the rail and traveling along the rail; and a device allowing a movement with respect to the metallic membrane of a point of impact of the laser beam on the metallic membrane, the movement being different from the travel effected by the support on the rail.
Claims19
A descaling device for descaling a metal membrane of a tank for at least one of transporting or storing gas in liquid form comprising:
- a rail configured to be secured to the metal membrane,
- a projection head for projecting a laser beam configured to descale the metal membrane, and
- a support interposed between the projection head and the rail and configured to be continually displaced along the rail,
- wherein the descaling device comprises a means allowing a movement, with respect to the metal membrane, of a point of impact of the laser beam on the metal membrane, the movement being distinct from a displacement applied by the support on the rail, and
- wherein the means allowing the movement of the point of impact is configured to incline the projection head according to an angle of incidence of between 5° and 70° with respect to a normal to the metal membrane.
