The axes of the end sectors of two pipes which are to be connected usually coincide. The device allows connections, when these axes make a certain angle between them, which can be oriented at will in space. The adjacent ends of the two pipes (1, 2) are cut obliquely in planes making the same angle with the longitudinal axes (3, 4) of the end sectors. Since the inner profile of this oblique section is elliptical to start with, it is made circular by a suitable thinning of the wall of the pipe. By virtue of this circular cross-section, the pipes may, before permanent connection, be oriented with respect to each other by simply rotating one with respect to the other, without there being any cranking inside the connection. A pipe thus connected can be used for drain water and water containing products in suspension. <IMAGE> |
