ABSTRACT:
The multiple wall angle connection allows to connect pipes and containers with great flexibility and a good compensation of the heat expansion. To connect two pipes (1, 2), for example, three coaxial angle connections (3, 4, 5) are interconnected. The internal connection (5) is connected to the first pipe (1) and the external connection (3) to the second pipe (2). The connections are interconnected by junction pieces (7) of semi-toric shape arranged at each side, at respective ends. Straight pipe portions (9-13 and 19-23) can be provided between the connections and the junction pieces. They can be cylindrical or conic. Control apparatus can be inserted within the space comprised between the different connections.
