Abstract

Se suministra una manguera flexible mejorada que tiene unamanguera interior corrugada con una pluralidad de proyecciones convexas y recesos abiertos alternados. Cada proyección tiene un vértice. Un manguito de refuerzo que tiene una pluralidad de aberturas que lo atraviesan se encuentra ubicado sobre el caño corrugado interior. El manguito de refuerzo se extiende entre los vértices de las proyecciones de la manguera interior corrugada, por encima de los recesos. Una capa exterior se coloca sobre el manguito de refuerzo. La capa exterior está conectada con las proyecciones del tubo corrugado interior a través de las aberturas del manguito de refuerzo anclando el manguito de refuerzo en su lugar y formando una pluralidad de huecos cerrados, de forma general anular de los recesos abiertos. Se describe también una manguera flexible con contención secundaria que presenta la construcción de manguera flexible, así como un método para producir la manguera flexible y la manguera de contención secundaria flexible.An improved flexible hose is supplied having a corrugated inner hose with a plurality of convex projections and alternating open recesses. Each projection has a vertex. A reinforcing sleeve having a plurality of openings running through it is located above the inner corrugated pipe. The reinforcing sleeve extends between the vertices of the projections of the corrugated inner hose, above the recesses. An outer layer is placed over the reinforcing sleeve. The outer layer is connected to the projections of the inner corrugated tube through the openings of the reinforcing sleeve by anchoring the reinforcing sleeve in place and forming a plurality of closed voids, generally annular of open recesses. Also described is a flexible hose with secondary containment featuring the flexible hose construction, as well as a method of producing the flexible hose and the flexible secondary containment hose.
