Abstract
(EN)
Method and device for fitting an inner tube in an existing pipeline, using air venting means, and also pipeline with inner tube of thermoplastics fitted in a stretched state therein. Lining of a pipeline (1) by placing therein an inner tube (2) of thermoplastic plastic and inflating it by medium pressure, thus forming an inner tube lining (2'), and subsequently cooling it under medium pressure. In order to prevent the inclusion of air between inside of pipeline (1) and outside of inner tube (2) to be inflated, longitudinal ribs of low height are provided on the outside (2a) of the inner tube (2). During the inflation the inner tube (2) also forms a sealing flange (20) extending over the end face (26) of the pipeline (1). A device for inflating the inner tube (2) comprises a coupling piece (17) which can be connected in a tension-resistant manner to the pipeline (1) and is provided with a connection (16) for introducing a pressure medium into inner tube (2).
(FR)
On effectue le revêtement d'un conduit (1) en y introduisant un tube intérieur (2) en thermoplastique, en le gonflant sous une pression moyenne, ledit tube intérieur constituant le revêtement (2'), et en le refroidissant ensuite sous une pression moyenne. Afin d'éviter le gonflement de l'air situé entre l'intérieur du conduit (1) et l'extérieur du tube intérieur (2), des nervures longitudinales de faible hauteur sont placées à l'extérieur (2a) du tube intérieur (2). Pendant le gonflement, le tube intérieur (2) forme également une bride d'étanchéité (20) s'étendant sur la face d'extrémité du conduit (1). Dispositif servant à gonfler le tube intérieur (2) et comprenant un élément d'accouplement (17) qu'on peut brancher sur le conduit (1) pour résister à la pression et qui est pourvu d'un raccord (16) servant à introduire un milieu sous pression dans le tube intérieur (2).
