Description

Technical Field

[0001] The utility model relates to the technical field of water supply equipment for ships, in particular to a seawater main pipe for ships with an anti-corrosion function. Background Art

[0002] The seawater main system on the ship is mainly used to provide cooling water, fire fighting water, ballast water, sanitation and deck washing water to the ship. The seawater enters the seawater main pipe of the seawater main pipe system after being filtered by the seawater main pipe system filter, and then distributed to various water supply pipelines through the water outlet of the seawater main pipe. The seawater main pipe system is directly related to the normal operation of the ship.

[0003] Due to the long-term exposure to humid and corrosive environments, the seawater main system needs to be protected by sacrificial anodes. However, sacrificial anodes are prone to wear and tear and need to be replaced regularly. When replacing sacrificial anodes in the existing seawater main system, water supply needs to be suspended, which will have an adverse impact on the normal lives of crew members and passengers, as well as the safety of ship personnel. Summary of the invention
