Description

Technical Field

[0001] This utility model relates to the field of oil pipeline protection technology, specifically to an external anti-corrosion coating equipment. Background Technology

[0002] Currently, steel pipes are commonly used for oil pipelines, primarily for transporting crude oil and petroleum products. They offer advantages such as large transport capacity, good sealing, low cost, and high safety. To improve the corrosion resistance of oil pipelines, it is typically necessary to coat the outer wall of the manufactured steel pipes with anti-rust oil. This prevents or slows down corrosion caused by chemical or electrochemical reactions during transportation and use, extending the service life of the steel pipes and reducing operating costs. Anti-corrosion steel pipes are typically coated with anti-corrosion materials on their outer wall during processing. However, existing steel pipe coating methods require workers to hold spray guns and apply the anti-rust oil to the outer wall of the pipe. During the coating process, workers must constantly change positions to ensure complete coverage, which is extremely time-consuming and labor-intensive. Therefore, this project was developed to address these issues. Utility Model Content

Based on the working groove 1 and the portal truss, a bracket 3 and a support roller 4 are set in the working groove 1 to provide temporary support for the steel pipe to be coated with oil. Horizontal moving components are set on both sides of the working groove 1, which can push the support 5 to move, thereby inserting the inner support fixing component at one end of the rotating table 6 into the end of the steel pipe and fixing the inner wall of the steel pipe. Then, under the cooperation of the drive control component, the rotation control of the steel pipe is realized. During the rotation of the steel pipe, the booster pump 9 is started, and the booster pump 9 is used to extract the rust-preventive oil in the rust-preventive oil storage tank 10 and further supply it to the position of the oil spray nozzle 8 through the flexible connection pipe. Under the action of pressure, the rust-preventive oil is sprayed onto the outer wall of the steel pipe. At the same time, the setting of the screw module 7 can realize the horizontal position adjustment of the oil spray nozzle 8, so that the entire oiling operation is automatic and continuous. In addition, a hot air drying mechanism is set at the top of the portal truss, which can make the rust-preventive oil dry quickly and improve the overall oiling operation efficiency.
