The quality of the steel pipe is not only related to its service life, but also related to its use efficiency. Then when we are buying steel pipes, we can roughly distinguish the quality of the steel pipes by the appearance of the steel pipes. If the surface of the steel pipes has numbness and is not smooth, then the quality of such steel pipes is relatively poor. And when buying, pay attention to observe whether there are scratches or cracks on the surface of the steel pipe. If this is the case, then the steel pipe is a poor quality product. And the inferior steel pipes are not metallic luster, and the color will be irregular light red or similar to the color of cast iron. Secondly, we can also take a look at the cross section of the steel pipe. If the cross section is uneven, it is likely to be a poor quality steel pipe.
