The present invention relates to an insulated pipe or piping system with a pipe (1) covered by at least one layer of insulation. A first sheet metal cladding element (2) surrounds the insulation-covered pipe (1). At least one band surrounds the first sheet metal cladding element. A longitudinal seam in the cladding element (2) includes a first edge (16) and a second edge (17). The first edge (16) is folded to form a Z-joint (22) shaped as a flattened Z with an opening (25) towards the joint and a bottom where the flattened Z is folded. The second edge (17) extends into the opening (25). A bead (11) is located along the circumference of the first sheet metal cladding element (2) between a reduced diameter, corrugated area (13) surrounding the first end portion (27), and the second end portion (28)The the corrugated area (13) forms a joint area (29). A second sheet metal cladding element includes an end portion surrounding the corrugated area (13) of first sheet metal cladding element (2) and abuts the bead (11) along the circumference of the first sheet metal cladding element (2). |
