Anti-corrosion protection machining method for ship metal outboard plate with outboard pipe

Abstract

The invention discloses an anti-corrosion protection processing method for a ship metal outboard plate with an outboard pipe, and particularly relates to the field of ship corrosion prevention. The method comprises the following steps of: performing polyethylene rotational molding corrosion prevention on the outer surface of a ship outboard plate and the inner surface of an auxiliary pipe by adopting a rotational molding integrated forming lining process, assembling a stainless steel circular ring on the ship outboard plate in an overlapping manner, and forming the annular compression type protection ring of the ship metal outboard plate anti-corrosion layer with the outboard pipe. The ship metal outboard plate anti-corrosion whole body with the outboard pipe is designed and manufactured according to the size, the polyethylene rotational molding corrosion prevention is conducted on the outer surface of a ship outboard plate and the inner surface of an outboard auxiliary pipe through the rotational molding integrated forming lining process, and then the stainless steel pressure protection ring is assembled on the outer surface of the ship plate, therefore, the ship outboard plate and the outboard auxiliary pipe have excellent anti-corrosion performance, the anti-corrosion layer has a protection function, the convenient installation and construction are achieved, and economical and practical performance are achieved.

Description

technical field [0001] The invention relates to the technical field of ship anti-corrosion, and more specifically, the invention relates to a method for anti-corrosion protection processing of ship metal outboard plates with outboard pipes. Background technique [0002] The ship metal outboard plate with outboard pipe is the most important part in the process of discharge to the marine environment in ships and marine engineering. It has been immersed in seawater highly corrosive environment for a long time. At present, in the manufacture of ship overboard discharge pipes, they are generally produced in sections, and then sprayed with various types of traditional paint anti-corrosion coating, galvanizing and modified epoxy resin, and then welded and installed on the ship hull. [0003] At present, various manufacturers do not have a superior overall anti-corrosion process and installation method for ship metal outboard plates with outboard tubes; the traditional paint coating...
