钢管的表面处理是控制防腐层质量的关键环节,通常都是在工厂生产线上进行的,抛射除锈因其除锈效率高、磨料利用率高、更适合大规模作业,所以在管道防腐领域应用广泛。文中结合生产实际,阐述了抛射除锈作业中磨料使用需要注意的几个问题。
Surface treatment of steel pipe is the key to control the quality of anti-corrosion coating. Usually it is carried out in the factory production line. Because of its high derusting efficiency and abrasive utilization rate, it is more suitable for large-scale work. Therefore, it is applied in pipeline anticorrosive field widely. In this paper, with the actual production, elaborated several issues that need to be noticed when using abrasives in projectile descaling.
