Description

Technical Field

[0001] The utility model relates to the technical field of pipeline protection, and specifically to a pipe sleeve for ship electrical pipelines. Background Technique

[0002] The pipe sleeve (marine sleeve) of ship electrical pipelines is an important protection device. Its main functions include protecting pipelines, wires and mechanical components from external influences. The sleeve can also protect the circuit connection points, preventing failures and malfunctions caused by reasons such as abrasion, vibration, thermal expansion and cold contraction. By sleeving an additional layer of sleeve on the pipe, it can play a role in absorbing vibration and reducing pressure, keeping the pipe in a relatively stable state.

[0003] In a ship pipeline insulation sleeve disclosed in the existing patent publication number CN214175786U, it includes a ship pipeline body. An adhesive layer is provided on the outer surface of the ship pipeline body. An insulation layer is wrapped outside the adhesive layer. A core material insulation layer is wrapped outside the insulation layer. A hard pipe shell layer is wrapped outside the core material insulation layer. A flame retardant layer is wrapped outside the hard pipe shell layer. An anti-corrosion layer is wrapped outside the flame retardant layer. A fiberglass cloth is wrapped outside the anti-corrosion layer. The inside of the hard pipe shell layer is cavity-shaped, and an inert gas is filled inside the hard pipe shell layer. A plurality of air guide pipes are provided on the outer surface of the hard pipe shell layer. The top ends of the air guide pipes are at the same horizontal plane as the outer surface of the fiberglass cloth, and sealant is filled inside the top ends of the air guide pipes.

[0004] The above-mentioned sleeve can protect the pipeline, but it is fixed on the pipeline, which is not convenient for protecting the pipeline connection points, and it is not convenient to separate from the pipeline subsequently, so it needs to be improved. In view of the above problems, a pipe sleeve for ship electrical pipelines is proposed. Content of the Utility Model
