2.Optimize the rolling process: The optimization of the rolling process includes selecting appropriate parameters such as rolling speed and rolling reduction. Reasonable rolling process can ensure that the steel pipe is evenly stressed during the rolling process and reduce the occurrence of surface defects.

3.Use advanced heat treatment technology: Heat treatment is an important means to improve the surface quality of seamless steel pipes. Through reasonable heat treatment process, the residual stress inside the steel pipe can be eliminated, the grains can be refined, the hardness and wear resistance of the steel pipe can be improved, thereby improving the surface quality.

4.Strengthen surface cleaning: In the production process of seamless steel pipes, surface cleaning should be strengthened. The cleanliness and surface finish of the steel pipe can be improved by removing impurities such as scale and rust on the surface of the steel pipe through pickling, shot peening and other methods.

5.Use high-quality lubricants: Using high-quality lubricants during the rolling process can reduce the friction between the steel pipe and the rollers, reduce the risk of surface scratches and wear, and thus improve the surface quality of seamless steel pipes. These methods can be used alone or in combination to achieve better results. In actual production, appropriate measures should be selected according to specific circumstances to improve the surface quality of seamless steel pipes.
