FAQ
How to distinguish the quality of seamless steel pipe?
Views: 7118 Update Date: Sep 13 , 2017
Good quality seamless steel pipe is uniform in composition, the cut head looks very structured, feeling is lubricated, rather than the feeling of burr thorns. So if it is residual quality, the cut head is uneven, and all the steel pipe looks dull. If it is poor quality seamless steel pipe, then there will be particularly significant in the color, showing a light red color, the temperature also can not be up to the standard.
The cross-section of poor seamless steel pipe is not a circular, may be oval or other shapes, which results in steel pipe manufacturers decrease materials. So it will not require the specification. In addition, if there is the appearance of scar, residual seamless steel pipe is very easy to see this appearance, high quality seamless steel pipe is not allowed.
