The invention concerns systems for connecting two connection pieces (1, 2) of tubes rotating about an axis (3), each comprising an inner passage (4, 5). Said system is essentially characterised in that the end (6, 7) of each connection piece (1, 2) has a ring-shaped bevel (8, 9) centred on the axis (3), the two circular edges (10, 11) of the two bevels (8, 9) being defined on the surface (12) of the wall (13, 14) of the passages (4, 5), the two connection pieces (1,2) being abutted such that the two circular edges (10, 11) merge, and it comprises means (20) for applying countering loads, on each connection piece respectively (1, 2) when they are abutted, said means (20) being arranged so that a molecular linkage is produced in the material at the two edges (10, 11) to result in a single sealed passage formed by the two passages (4, 5) of the two connection pieces thus connected. The inventive system is in particular advantageously used for connecting tubes or the like, such as conduits, piping systems and so on, which are designed to transport high purity fluids, of all types, whether industrial, chemical, pharmaceutical or food product fluids. |
