Roller pipe

Unlike honing pipes, the surface of rolled pipes undergoes plastic deformation of the metal due to rolling, and the surface structure is processed by cold quenching, forming a dense fibrous structure, creating a residual stress layer, increasing hardness and strength, thereby improving the wear resistance, corrosion resistance, and compatibility of the rolled pipe surface. Rolling is a non-cutting plastic processing method. Large-diameter rolled pipes often encounter some issues during use. Generally speaking, the pipes that cause problems are inferior products. They not only affect installation but can also cause significant harm during use. For better procurement and use, today, Dawang Steel Pipe will tell us how to distinguish the advantages and disadvantages of large-diameter rolled pipes. First, we need to look at the surface; if there are scars on the surface, it indicates that the raw materials used for this square pipe are poor, with a high impurity content, leading to the appearance of scars. This phenomenon can only be discovered by careful observation. Second, look at the surface of the large-diameter rolled pipe; high-quality products have a more uniform line distribution and will not have cracks. If cracks are found, it indicates that the quality of the raw materials used is too poor, unable to withstand high temperatures during the production process, ultimately leading to cracks.
