APPARATUS FOR THE ANTICORROSION COATING AND THE THERMALLY INSULATING COATING OF TUBULAR BODIES AND CONDUITS FOR THE TRANSPORT OF FLUID

摘要

Method for the anticorrosion and thermally insulating coating of tubular bodies and conduits for the transport of fluids, comprising the following stages in sequence. a) positioning on a tubular body (1, 17, 17', 17'') requiring coating a series of devices (2, 4, 5, 5', 5'') for automatic coating of such tubular body (1, 17, 17', 17'') provided with suitable means (6, 7, 8, 9, 10, 11) for movement along such tubular body (1, 17, 17', 17'') and/or moving supporting equipment (18, 21) capable of permitting such tubular body (1, 17, 17', 17'') to move and if appropriate rotate in such automated coating devices (2, 4, 5), b) sandblasting of the surface of such tubular body (1, 17, 17', 17'') using a suitable granular metal material, c) heating the surface of such tubular body (1, 17, 17', 17''), d) applying an epoxy resin and an adhesive resin to such tubular body (1, 17, 17', 17''), e) final coating of the tubular body (1, 17, 17', 17'') with thermoplastic, thermohardening or the like coating material.
