Problems solved by technology
[0002] The drain pipe is used to discharge seawater from the ballast tank during the shipping process. The ballast tank in the ship is an isolated indoor space. The depth of the draft is controlled by the switch, thereby increasing the draft of the ship to achieve balance. The length of the ballast tank After time is used, the interior of the ballast tank is prone to corrosion, which leads to the accelerated aging of the ballast tank, and when the seawater is discharged, it is necessary to discharge the seawater inside the ballast tank through the drain pipe, so as to ensure the stability of the ship In the process of discharging seawater, the internal pressure of the drain pipe increases due to the passage of high-speed water. After a long period of use, it is easy to cause cracks in the drain pipe, thus affecting the draft of the ship.

The invention relates to the technical field of ships, in particular to an anti-corrosion PE pipe for ship drainage, which comprises a ship, a seawater ballast tank is fixedly mounted in an inner cavity of the ship, a drainage pipe is fixedly mounted on the front surface of the seawater ballast tank, and an anti-corrosion coating is fixedly mounted on the inner wall of the seawater ballast tank. The inner wall of the drainage pipe is fixedly provided with a buffer device, the anti-corrosion coating comprises organic silicon resin paint, perchloro-ethylene paint, rich primer, epoxy glass flakes and vinyl resin, and the bottom of the organic silicon resin paint is fixedly connected with the inner wall of the seawater ballast tank. Seawater easily corrodes the inner cavity of the seawater ballast tank, after the anticorrosive coating is added, the corrosion degree of the seawater to the inner wall of the seawater ballast tank can be reduced after long-time use, the aging time of the interior of the seawater ballast tank is greatly delayed, the service life of the seawater ballast tank is prolonged, meanwhile, the maintenance frequency of workers is reduced, and the service life of the seawater ballast tank is prolonged. And the labor intensity of workers is reduced.
