Under normal circumstances, small holes will appear on its surface. These small holes are mainly caused by the hot rolling of the material during the processing. The high surface temperature of the part will cause the part to produce pores, and thus the surface of the part Leave a lot of pitting.
In response to this phenomenon, we have to choose a pipe with a low degree of corrosion, and the inner wall of the pipe should be as thick as possible, so that the hot-rolled pipe can be processed to reduce the generation of pores and increase the production quality of the steel pipe. Pitting and pores on the surface of the pipe are also related to the defects of the pipe itself. We should try to avoid the problems caused by the pipe itself, and try to further process the pipe to reduce the occurrence of defects such as pores and pits, and increase the production of pipes. Efficiency and quality.
