Embodiment Construction

[0028] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0029] Such as figure 1 As shown, the pipeline 1 is installed in the bulkhead of the ship, and the casing 3 is sleeved on the outside of the pipeline 1. The casing 3 is connected to the bulkhead through the outer plate 2, and the outer plate 2 and the casing 3 are welded. The inner wall of the pipeline 1 is coated with a protective layer (preferably a PE coating), and a cooling liquid (preferably water) is introduced into the pipeline 1 to control the inner wall temperature of the pipeline 1 to be less than the maximum temperature resistance of the protective layer during the welding process. The maximum temperature resistance of the PE coating in the present invention is 70°C. When there is a cooling liquid in the pipeline 1, it can ensure that the heat generated by welding is transferred to the p...

Abstract

The invention belongs to the technical field of ship construction and discloses an installation method of a ship pipeline. The installation method of the ship pipeline comprises the steps that a protection layer is coated on the inner wall of the pipeline; the pipeline is welded to an outer plate, a cooling liquid is introduced into the pipeline so that in the welding process, temperature of the inner wall of the pipeline is controlled to be lower than maximum temperature resistance of the protection layer. According to the installation method of the ship pipeline, by introducing the cooling liquid into the pipeline, in the welding process, temperature of the inner wall of the pipeline is controlled to be lower than the maximum temperature resistance of the protection layer; thus the protection layer inside the pipeline is effectively guaranteed not to be destroyed; subsequent supplementary coating cost is lowered; construction efficiency is improved; the construction period is shortened; and the problem that temperature of the inner wall of an existing pipeline cannot be effectively controlled is solved.

Description

technical field [0001] The invention relates to the technical field of ship building, in particular to a method for installing a ship pipeline. Background technique [0002] In the shipbuilding industry, in order to reduce the corrosion of pipelines, anti-corrosion paint is usually added to the pipelines or stainless steel pipelines are used. The anti-corrosion effect of the former is not ideal, and the anti-corrosion period is not long. higher. [0003] With the development of ship supporting industry and anti-corrosion materials, PE-lined pipes have been gradually applied in the field of ship construction. This pipe not only has good anti-corrosion effect, but also has low cost, and is more and more popular in the ship field. However, when the pipeline is welded and fixed, how to avoid damage to the PE coating by controlling the temperature of the inner wall of the pipeline is a major problem in this field, which seriously affects the construction efficiency of the ship. ...
