Roller pipe
Unlike honed pipes, the processing principle of rolled pipes is: it is a type of pressure fine machining that utilizes the cold plastic characteristics of metals at room temperature. It applies a certain pressure on the surface of the workpiece using rolling tools, causing the metal surface to undergo plastic flow, filling the original grooves and reducing the surface roughness of the workpiece. The processing time for rolled pipes is greatly shortened, and the speed of mass production is faster. The straightness and precision of rolled pipes are far superior to honed pipes. The surface hardness of rolled pipes is higher than that of honed pipes, which improves their service life. Rolled pipes are widely used in many markets, and we will analyze and introduce the characteristics that allow for their extensive application. Firstly, due to their corrosion resistance, as they are made using a galvanizing process, the corrosion resistance of rolled pipes can be greatly improved. The surface after galvanization appears smoother, making it very suitable for any occasion. Secondly, their toughness allows them to be buried underground without deforming or breaking, regardless of whether vehicles or people walk on the ground, demonstrating excellent compressive strength.
