Surface treatment methods of high-frequency welded steel pipes

With the continuous advancement of China’s economy, the nation has vigorously promoted the development of the energy industry. Long-distance API oil and gas pipelines play a crucial role in ensuring energy security. In the anti-corrosion construction process of oil and gas pipelines, the surface treatment of high-frequency welded steel pipes is one of the key factors affecting the service life of the anti-corrosion coating. It is the fundamental condition for achieving strong adhesion between the coating and the steel pipe. According to research, the lifespan of the anti-corrosion layer is influenced by factors such as coating type, construction quality, and environmental conditions. Among these, surface treatment of the steel pipe accounts for approximately 50% of the impact. Therefore, it is essential to strictly adhere to the technical specifications for the surface of thick-walled steel pipes and to continually explore and refine surface treatment methods to improve coating performance and durability.
