<p>This device for jump jointing piping elements (10, 12) having relative movements at least along one direction, comprises a sealing sleeve tube (16) made of deformable plastic material to be sealingly fixed on the end zones opposite said piping elements. It further comprises a pipe lining (24) forming piping element located in the sleeve tube (16) with its opposite end zones (26, 28) mounted each in a piping element (10, 12) with clearance for absorbing the relative displacements of said piping elements, said pipe lining (24) comprising an intermediate portion (30) extending between its end zones (26, 28) and defining externally a supporting surface for said sleeve tube (16).</p> |
