Abstract
(EN)
Means for applying a finishing layer of plastic material to the surface of a pipe, comprising a ring (1) of which the inlet diameter (2) is larger than its outlet diameter (3), the internal surface (4) of said ring further providing for a degressive variation of the inner diameter between its inlet and its outlet; method for applying a finishing layer wherein these means are used, and pipe thus coated.
(FR)
Moyens pour l'application d'une couche de finition de matière plastique à la surface d'un tuyau, comprenant une bague (1) dont le diamètre d'entrée (2) est supérieur à son diamètre de sortie (3), la surface intérieure (4) de ladite bague assurant en outre une variation dégressive du diamètre intérieur entre son entrée et sa sortie; procédé d'application d'une couche de finition dans lequel ces moyens sont utilisés et tuyau revêtu.
