Title (EN) METHOD FOR COATING THE INNER WALL OF A TUBE
(FR) PROCÉDÉ DE REVÊTEMENT DE LA PAROI INTERNE D'UN TUBE
Abstract:
(EN) The invention relates to a method for forming a coating in the inner wall of a tube, including the following operations: - moving a segment of a liquid composition of coating particles in suspension inside the tube at a constant controlled speed at least equal to 2 cm/s, so as to drive a homogeneous liquid film over the inner wall of the tube, and - allowing the solvent of the liquid composition to evaporate and the coating particles in suspension to be deposited on the inner wall of the tube.
(FR) L'invention concerne un procédé de formation d'un revêtement dans la paroi interne d'un tube, comprenant les opérations suivantes, consistant à : - déplacer un segment d'une composition liquide de particules de revêtement en suspension à l'intérieur du tube à une vitesse régulée constante au moins égale à 2 cm/s, de manière à entraîner un film liquide homogène sur la paroi interne du tube, et - laisser le solvant de la composition liquide s'évaporer et les particules de revêtement en suspension se déposer sur la paroi interne du tube.
