Description

Technical Field

[0001] The utility model relates to the technical field of pipeline installation, in particular to a heat-insulating pipeline through-cabin structure. Background Art

[0002] There are generally two types of watertight pipeline through-tank structures for ships and offshore engineering platforms: casing through-tank and double-plate through-tank. The problem is that both of these through-tank structures use pipelines directly connected to the hull bulkhead, which causes the heat of the pipelines to be easily transferred to the hull bulkhead, especially high-temperature pipelines, which will bring great safety hazards to ships and offshore engineering platforms.

[0003] After searching, Chinese patent application number (CN205978843U) discloses a heat-insulating pipeline through-cabin structure. Although the device in the application avoids the heat transfer of the high-temperature pipeline to the hull structure, when the pipeline is repaired and replaced, it is not necessary to destroy the hull bulkhead, and only the bolts need to be removed. However, the high-temperature pipeline is separated from the bulkhead by a sleeve, and the heat dissipated by the high-temperature pipeline is still accumulated between the sleeve and the high-temperature pipeline, resulting in poor cooling effect. At the same time, the high-temperature pipeline and the sleeve are fixedly connected by bolts, which makes it inconvenient to disassemble after long-term use. Therefore, the utility model provides a heat-insulating pipeline through-cabin structure to solve the above-mentioned problems. Utility Model Content
