Description

TECHNICAL FIELD

[0002] Pipeline anticorrosion refers to measures to slow down or prevent pipeline corrosion and deterioration under the chemical and electrochemical effects of internal and external media or due to metabolic activities of microorganisms. Pipelines for transporting oil and gas are mostly in complex soil environments, and the transported media are mostly corrosive, so the inner and outer walls of the pipeline can be corroded. Once the pipeline is corroded and perforated, oil and gas leakage will occur, which not only disrupts transportation but also pollutes the environment and may even cause fires and harm. The anticorrosive pipeline conveying device is mainly used for conveying anticorrosive materials in the inner diameter of the anticorrosive pipeline to achieve more uniform anticorrosive coating.

[0003] In the prior art, during the process of spraying anticorrosive coating on the anticorrosive pipeline, the device will come into contact with the anticorrosive pipeline. In addition, the anticorrosive pipeline may fall into impurities during storage, transportation, and related processing, which may cause damage to the inner surface of the anticorrosive pipeline. For example, the patent "Anticorrosive Pipeline Conveying Device" (Authorization Announcement No. CN215141301U) is designed for diameter spraying without impurities, and the "auxiliary rolling column" and "roller" will come into contact with the anticorrosive pipeline, which may also cause damage to the inner surface of the anticorrosive pipeline.

[0004] Therefore, an anticorrosive pipeline conveying device capable of avoiding damage is proposed to solve the above problems. INVENTION CONTENTS
