  • 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.

  • Patent number: 9217520
    Abstract: Method to make a curved tubular element in order to convey abrasive materials such as concrete or suchlike, which comprises a first step of making at least a curved component made of a material highly resistant to wear, having an arched transverse development comprised between 90° and 360°, a second step of inserting the curved component into a shaping mold with a molding surface with a shape mating with the outer surface of at least a part of the curved tubular element to be made, so that, together with the molding surface, the curved component defines a casting chamber, and a third step in which material with a low resistance to wear is cast in the casting chamber in order to make, externally to the curved component, at least a part of a tubular body of the curved tubular element.

  • Publication number: 20140283942
    Abstract: A method to make a curved tubular element comprising obtaining a first external curved tubular component, and a second internal curved component made of a material with a greater resistance to wear than the first external curved tubular component, and having a cross section which covers a portion of the internal surface of the first external curved tubular component. The first external curved tubular component includes at least two parts. Each of the parts has a cross section which is a respective portion of the complete tubular section of the first external curved tubular component; to bring the at least two parts near each other along respective connection edges, disposing the second internal curved component internally in contact with at least one of the two parts; to weld the at least two parts to define the first external curved tubular component and to enclose therein the second internal curved component.
