Abstract

a. Tuyau avec corps d'obturation externe. b. Le tuyau est en un matériau thermoplastique tel que le chlorure de polyvinyle, comportant extérieurement un corps d'obturation élastique en mousse de plastique, de préférence en mousse de polyuréthane déposée sur la face externe du tuyau, une couche de résine thermodurcissable contenant des particules électriquement conductrices, de préférence des particules de carbone par exemple des particules de suie, étant disposée entre le corps et le tuyau afin d'assurer une bonne conduction, le corps en mousse de plastique possédant une surface fermée solidaire du corps en mousse de plastique. c. Application dans l'industrie minière.
