  • Patent number: 10689211
    Abstract: A method and apparatus for producing a curved tubular segment includes obtaining a curved external tubular element and a curved internal tubular element. The curved internal tubular element is made of a material having a resistance to wear greater than that of the curved external tubular element and has a cross section such as to cover at least part of the internal surface of the curved external tubular element. The curved internal tubular element is inserted inside the curved external tubular element after heating the latter by a heating unit. To form the curved external tubular element on the exact geometry of the curved internal tubular element, a molding unit and a cooling unit are used to obtain a curved tubular segment without spaces between the curved external tubular element and the curved internal tubular element.
