- Abstract:
- The anticorrosion treatment is an important content in the design of submarine outfall pipelines. It is difficult to repair the anticorrosive coating in the traditional sea discharge pipeline, due to great difficulty in quality control and long construction cycle, which cannot guarantee the service life of the pipeline. According to the characteristics of long distance submarine outfall pipeline, this paper puts forward the design scheme of canceling the internal anticorrosive coating and compensating the internal corrosion by appropriately increasing the corrosion allowance of the pipeline wall thickness, and selecting the appropriate corrosion allowance through the internal corrosion detection test of the pipeline in the new area pipeline project of Liaodong Bay. The project was completed in September 2017 and has been running well. The relevant test conclusions and design methods can provide reference for subsequent engineering design.
