During the use of pipelines, the daily maintenance of steel pipes and pipe fittings is very important. Through regular maintenance and inspection, the service life of pipelines and pipe fittings can be prolonged.

With the sustainable development of China's economy and the vigorous development of the energy industry, long-distance oil and gas pipeline is an important way of energy transportation. In the construction of oil and gas pipeline, steel pipe surface treatment is one of the key factors determining the service life of the pipeline, and it is the premise of whether the coating can be firmly combined with the steel pipe.

According to the verification of the organization, in addition to the factors such as coating type, coating quality and construction environment, the impact of steel pipe surface treatment on the coating life accounts for about 50%. Therefore, it is necessary to continuously explore and summarize and constantly improve the steel pipe surface treatment method in strict accordance with the requirements of coating specification for steel pipe surface.
