Patent attributes
A cladding tube (1) for enveloping an underwater conduit (2), such as a pipeline or a cable line, has at least one clamping portion (6), which comprises at least one deformation portion (6A, 6B, 6C) being integrally manufactured with the cladding tube (1), which deformation portion (6A, 6B, 6C) is a first wall portion of the cladding tube (1), which has a larger thickness in the radial direction than at least one second wall portion (8) of the clamping portion concerned, in such manner that by the larger thickness the first wall portion is, and the at least one second wall portion (8) is not, pressed against the underwater conduit (2) by a tensioning strap (7) being tensioned all round. The deformation portion concerned is easy to produce, durable and reliable. Thanks to the at least one clamping portion the cladding tube can be designed in harder and lower-cost materials than the soft, flexible poly urethane, which is usually applied nowadays.
