Anti-corrosion pipeline production forming method

Abstract

The invention relates to an anti-corrosion pipeline production forming method. The method mainly comprises the following steps of equipment inspection, pipeline mounting, surface spraying and pipelinestorage. Anti-corrosion pipeline surface spraying equipment comprises a mounting base plate, a supporting external member and a spraying external member, the supporting external member is mounted onthe mounting base plate, and the spraying external member is mounted on the supporting external member in a sliding connection manner. The method can solve the following problems that when anti-corrosion materials are smeared on the surface of an existing pipeline, a, the outer side of the pipeline needs to be clamped when the anti-corrosion materials are smeared on the surface of the existing pipeline, the situation of missing spraying often occurs when the surface is sprayed, manual re-spraying is needed, the workload of staff is increased, and an anti-corrosion solution on the surface of the pipeline is sprayed unevenly; and b, after the anti-corrosion materials are smeared on the surface of the existing pipeline, the anti-corrosion solution on the surface of the pipeline needs to be dried, an anti-corrosion layer is prone to being scratched in the transportation process, consequently, the anti-corrosion effect of the pipeline is reduced, and the quality of the pipeline is influenced.

Description

Technical field[0001]The invention relates to the technical field of pipeline production, in particular to a method for forming anticorrosive pipelines.Background technique[0002]Anti-corrosion pipeline refers to the pipeline that has undergone anti-corrosion processing and treatment, which can effectively prevent or slow down the corrosion caused by chemical or electrochemical reactions during transportation and use. Most of the pipelines that transport oil and gas are in a complex soil environment. The medium is also corrosive, so the inner and outer walls of the pipeline may be corroded. Once the pipeline is corroded and perforated, it will cause oil and gas leakage, which will not only interrupt the transportation, but also pollute the environment, and may even cause fires and cause harm. Therefore, preventing pipeline corrosion is an important part of the pipeline process. The surface of the pipeline is evenly and densely coated with anti-corrosion materials to isolate the pipel...

AI Technical Summary

Problems solved by technology

[0003] The following problems often exist when the existing pipeline surface is smeared with anti-corrosion materials: a: when the existing pipeline surface is smeared with anti-corrosion materials, it is often necessary to clamp the outside of the pipeline. In the event of spraying leakage, manual re-spraying is required, which greatly increases the workload of employees, and after multiple sprayings, it is easy to cause uneven spraying of anti-corrosion solution on the surface of the pipeline; b: the existing pipeline is being sprayed After the surface anti-corrosion material is applied, it is often necessary to move the pipeline to an oven to dry the anti-corrosion solution on the surface of the pipeline. During transportation, it is very easy to cause scratches on the anti-corrosion layer, thereby reducing the anti-corrosion effect of the pipeline and affecting the quality of the pipeline
