<p>Method for the implementation in situ of the three-layer coating with thermoplastic materials for the anticorrosive protection of welding joints of coated metal pipes, and/or of damaged coating areas, by wrapping up a ready-to use sheathing/band or tape, made of thermoplastic materials. The application of the sheathing/band or of the tape onto the joint is carried out mechanically by means of a suitable roll, e.g. in silicone rubber, said roll, carried by a suitable device placed on the pipe in the area to be coated, turning around the pipe wrapping and pressing with the desired pressure the sheathing/band/tape onto the pipe itself and ensuring a strong adherence to the support/pipe and the absence of air bubbles entrapped between the sheathing/tape and the pipe. <IMAGE></p> |
