Insulation pipes need to be anti-corrosion. First of all, anti-corrosion is a very important part of pipeline engineering, which can protect the pipeline from corrosion and damage, thereby prolonging the service life of the pipeline.
Although the main function of the insulation pipeline is to keep warm, in the process of long-term use, the pipeline will be eroded by various environmental factors, such as acid, alkali, salt, oxygen, etc., which will cause corrosion to the pipeline, thereby affecting the service life of the pipeline. Therefore, in order to protect the insulated pipes, anti-corrosion treatment is required.
Secondly, the anti-corrosion treatment of insulated pipes needs to be selected and designed according to the material, use environment and engineering requirements of the pipeline. Commonly used anti-corrosion methods include coating anti-corrosion, electrochemical anti-corrosion and thermal spraying anti-corrosion. Coating anti-corrosion is to coat a layer of corrosion-resistant paint on the surface of the pipeline to form a protective film to isolate the contact between the pipeline and the external environment, so as to achieve the purpose of anti-corrosion. Electrochemical corrosion protection is a method of reducing the corrosion rate by applying an applied current to change the corrosion potential. Thermal spraying anti-corrosion is to spray the molten spraying material on the surface of the pipeline through high-speed air flow to form a dense protective layer, so as to achieve the purpose of anti-corrosion.
Finally, the anti-corrosion treatment of the insulated pipeline needs to be inspected and controlled during the construction process to ensure that the quality and thickness of the anti-corrosion layer meet the requirements to ensure the service life and safety of the pipeline. At the same time, regular inspection and maintenance are also required during use to find and deal with corrosion problems in time, so as to ensure the normal operation and service life of the pipeline.
To sum up, insulated pipes need to be treated with anti-corrosion to protect the pipes from corrosion and damage and prolong the service life of the pipes. Insulated pipes
