Title (EN) IMPROVEMENTS IN AND RELATING TO TUBING
(FR) AMELIORATIONS RELATIVES A DES TUBES
Abstract:
(EN) A braided or knitted flexible textile tube (4) is provided with a flexible foamed polymeric lining (17) over the inner surface thereof, preferably of a silicone elastomer. The tube (4) is preferably made of glass or polyester fibre and, optionally, has a further flexible textile tube (12) as a liner, the flexible foamed polymeric material (17) being enclosed between the outer (4) and inner (12) tubes.
(FR) Un tube en textile flexible tricoté ou tressé (4) est pourvu, sur sa surface interne, d'un revêtement intérieur polymère en mousse flexible (17), de préférence composé d'un élastomère de silicone. Le tube (4) est de préférence composé d'une fibre de verre ou de polyester, et, éventuellement, comprend un autre tube en textile flexible (12) comme revêtement interne, le matériau polymère flexible en mousse (17) étant enfermé entre les tubes externe (4) et interne (12).
