Title (EN) MAKING MULTILAYER COMPOSITE PIPE FOR LIQUID CONVEYANCE
(FR) FABRICATION D'UN TUYAU POUR LE TRANSPORT DE LIQUIDES
Abstract: front page image
(EN)The invention relates to an apparatus for making a multilayer composite pipe. The multilayer composite pipe comprises an innermost layer (2) made of plastic. The pipe has a seamless metal layer (4) or a metal layer (4) having an axial, non-overlapping seam. The outer surface of the metal layer is treated for changing its outer appearance. There-after a transparent outermost layer (8) is provided on the outer surface of the metal layer. The structure of the pipe is such that the pipe can be permanently bent to certain angles without significant spring back.
(FR)L'invention concerne un équipement pour fabriquer un tuyau composite multicouche. Le tuyau composite multicouche comprend une couche la plus à l'intérieur faite de plastique. Le tuyau comporte une couche métallique sans soudure ou une couche métallique ayant une soudure axiale sans chevauchement. On traite la surface extérieure de la couche métallique pour modifier son apparence extérieure. Par la suite on dispose une couche la plus à l'extérieur, transparente, sur la surface extérieure de la couche métallique. La structure du tuyau est telle qu'on peut le cintrer de façon permanente à des angles donnés sans avoir de retour élastique notable.
