Device and method for thermally insulating a region of connection of connection end fittings of two lagged underwater pipes

摘要

The thermal insulation device comprises a thermally insulating sleeve (15) covering at least a portion of the length of each connection end fitting (10) adjacent to the end flange (11) of said end fitting (10) and leaving said end flange (11) uncovered, and a removable thermal‑protection cover (20) covering the gap left between the two thermally insulating sleeves (15) after the end flanges (11) of the two end fittings (10) have been connected using connecting members (5), said removable cover (20) being fixed to each thermally insulating sleeve (15).
