How to judge the quality of anticorrosive spiral steel pipe
The corrosion-resistant spiral steel pipe material will produce different sparks through contact with the grinding wheel. We can tell what kind of anticorrosive spiral steel pipe is made by observing the spark. Can check 301 anticorrosive spiral steel pipe belt, anticorrosive spiral steel pipe plate, anticorrosive spiral steel pipe rod, anticorrosive spiral steel pipe line, anticorrosive spiral steel pipe ...
1. The sparks emitted by SKH2 steel are arc-shaped.
2.304 The anti-corrosion spiral steel pipe sprayed sparks are relatively short
3.20C steel sparks are long and scattered
4. Sparks from SK5 steel are far and disorderly
Through such different sparks, it can be judged whether it is a 304 anticorrosive spiral steel pipe belt. The characteristics of the sparks are chrysanthemum-shaped, spear-shaped, white jade sparks, and split sword sparks. The results obtained by testing steel are not uniform. Under different conditions, there will be some interference, but in general, the basic situation will not change greatly.
