What factors cause surface problems of honed and rolled pipes?

Many people do not pay much attention to the surface problems when choosing honed and rolled pipes. In fact, surface problems also have a great impact on the use of honed and rolled pipes, which will affect the future use and life of the honed and rolled pipes. What factors cause surface problems of honed and rolled pipes?
1. Quality of material selection
Under normal circumstances, small holes will appear on the surface of our honed and rolled tubes. These small holes are mainly caused by the hot rolling of the material during processing. When the surface temperature of the parts is high, pores will appear on the parts, leaving a lot of pitting on the surface of the parts. Therefore, we must choose pipes with low corrosion degree, and the inner wall of the pipe should be as thick as possible. Only by processing such hot-rolled pipes can we reduce the occurrence of pores and improve the production quality of steel pipes. Imitation marble decorative board
2. The shape of the steel pipe
Generally we use honingRolled tubeThey are relatively thin, which causes the pores to be on the surface of the pipe. We can increase the thickness and diameter of the pipe to reduce the attachment points of the pores and prevent them from appearing on the surface.
3. Dealing with defects in the pipe itself
The appearance of pits and pores on the surface of honed and rolled pipes is also related to the defects of the pipe itself. We should try to avoid the problems caused by the pipe itself, try to further process the pipe, reduce the occurrence of defects such as pores and pits, and improve the production efficiency and quality of the pipe.
