Description

Technical Field

[0001] The utility model relates to the technical field of conveying pipelines, in particular to an anti-corrosion coated metal pipeline. Background Art

[0002] As a common mode of transportation, pipeline transportation has the advantages of good sealing and strong stability. Since the connections in the pipeline system are sealed, it can effectively prevent fluid or gas leakage, which can not only reduce the waste of energy and resources, but also improve the safety of operation. At the same time, pipeline transportation can maintain the stable flow of fluid or gas, reduce pressure loss and flow resistance, and reduce energy consumption. In addition, pipeline transportation also has high transportation efficiency and operational reliability, can meet the transportation needs of a large number of fluids or gases, and can be transported over long distances. Therefore, pipeline transportation is widely used in industrial production, including oil, natural gas, chemical industry, water treatment and other fields.

[0003] In the prior art, pipelines usually do not have anti-corrosion properties, which means that pipelines are susceptible to corrosion during long-term use, resulting in damage to the pipelines and functional failure. In addition, pipeline connections in the prior art are usually unable to monitor water leakage in real time. Pipeline connections are the most prone to leakage in the pipeline system. Pipeline leakage may occur due to loose connections or external forces. However, traditional pipeline connection methods make it difficult to monitor and detect leakage in real time.

[0004] Therefore, those skilled in the art provide a metal pipeline with an anti-corrosion coating to solve the problems raised in the above background technology. Utility Model Content
