Problems solved by technology
[0002] At present, in operating ships, the seawater cooling system is frequently used, but it is still highly corrosive. As a result, seawater pipelines are often leaked due to seawater corrosion, which has certain safety hazards.
In the prior art, the surface of the seawater pipeline is generally painted with anti-corrosion materials, such as polyethylene, epoxy paint and other materials, to isolate the contact between the seawater and the seawater pipeline to prevent the seawater pipeline from being corroded, but the above method Complicated operation and difficult maintenance
Or set up a branch road on the main road of the seawater pipeline. The branch road and the main road of the seawater pipeline are connected by welding, and zinc blocks are installed on the branch road to prevent the seawater pipeline from being corroded. The volume of the branch is limited by the diameter of the branch. At the same time, the length of the zinc block is too long to affect the liquid flow in the main pipeline of the seawater pipeline.

Embodiment Construction
[0042] A preferred embodiment will be given below, and the present invention will be described more clearly and completely in conjunction with the accompanying drawings.
[0043] Such as Figure 1-3 The anti-corrosion device for the main pipeline of the seawater pipeline includes a main pipeline of seawater pipeline 600 , a blind flange 100 , a screw part 200 and an anti-corrosion zinc part 300 . For clarity, figure 1 and figure 2 Only part of the main seawater pipeline 600 is shown.
[0044] Wherein, the seawater pipeline main pipe 600 is fixed with a main pipe flange 610. In this embodiment, the main pipe flange 610 is fixedly connected with the seawater main pipe 600 by welding, and the main pipe flange 610 is connected to the blind plate through bolts and nuts. Flange 100 connection.
[0045] The screw part 200 is fixed on the surface of the blind flange 100. In this embodiment, the screw part 200 is welded to the center of the blind flange 100, such as figure 2 sho...
