Water pressure test detection

High pressure water phosphorus removal is an important process in steel rolling. Its working principle is to use the rapid cooling of water to create a temperature difference between the oxidized steel skin and the billet, causing the surface oxide skin to crack and fall off mechanically. 2. Use the impact force generated by high-pressure water to remove the oxide steel scale on the surface of the billet. Avoiding the oxidation skin carried on the outer surface from embedding into the outer surface of the steel pipe to form a slight pitting during rolling, while improving the smoothness of the outer surface, reducing secondary oxidation, improving the quality of the outer surface of the steel pipe, reducing costs for subsequent precision processing, and improving overall quality, providing an important condition.
