The application discloses an anti-corrosion device for a weld joint of a natural gas pipeline and a method for anti-corrosion construction thereof, which relate to the technical field of pipeline construction and include a base, a first cover assembly, a second cover assembly, a telescopic member, and a water-retaining agent. The interior of the base is provided with a cavity, the first surface of the base is provided with a water seepage hole, and the water seepage hole communicates with the cavity, the first protective cover is opposite to the inner concave surface of the second protective cover to form a channel for placing the pipeline, and the telescopic element is arranged on the first In the cavity, the first end of the telescopic element is connected to the first push plate, and the second end of the telescopic element is connected to the second surface of the first cavity. The water retaining agent is filled in the cavity and located on the first surface of the first push plate and the base between and between the second push plate and the second surface of the base. In this application, through the water absorption and release of the water retaining agent, the anti-corrosion of the pipeline is adjusted accordingly under the influence of different environmental factors, and the protective cover is driven by the support to realize the abutment coating and separation and ventilation of the welding joint of the pipeline, which improves the anti-corrosion Effect.
Description
technical field [0001] The application relates to the technical field of pipeline construction, in particular to a natural gas pipeline welding joint anti-corrosion device and a method for anti-corrosion construction. Background technique [0002] Oil and gas gathering and transportation is the whole process of collecting oil, associated natural gas and other products produced by scattered oil wells, and after necessary treatment and preliminary processing, qualified oil and natural gas are exported to refineries and natural gas users respectively. During the transportation process, if the pipeline is corroded and damaged, it will cause leakage during the external transportation. Pipeline corrosion is based on the specific pipeline environment, chemical reactions, electrochemical reactions and microbial erosion that occur in all metallic and non-metallic materials in the pipeline system, which can lead to damage and loss of pipeline structures and other materials, and, in ad...
