Abstract

Sistema de fabricación de tubos reforzados interiormente de material sintético, caracterizado porque en un proceso de fabricación del tubo partiendo de pletinas metálicas empiladas o enrolladas y durante la operación de doblado de la pletina para conformar el tubo, se inyecta material sintético expansible del tipo de poliuretano o polietileno o mismo PVC, que se adhiere perfectamente a las paredes del tubo, que se acaba de fabricar, y que se dilata fuertemente alcanzando su máximo volumen después de llenado el tubo, con lo cual se consigue un perfecto recubrimiento interior del mismo, pudiendo ser el tubo cilíndrico, ovalado, de sección cuadrada, rectangular o cualquier tipo de perfil.
