How To Distinguish True And False Stainless Steel Mirror Tubes

How to distinguish true from false Sanitary Valve

1. Comparison items: tooth edge and tooth pitch:

2. Standard naked eye sees sharp tooth edge, uniform tooth pitch and bright.

3. Hand feel: smooth tooth edge, standard processing depth, straight core and uniform wall, smooth flow.

4. Mechanical treatment before leaving the factory, no clamps or debris on the surface.

5. Low carbon content, corrosion resistance, oxidation resistance, strong toughness, strong pressure resistance.

6. Roughly made, unfavorable and thick tooth edge, irregular tooth pitch, tooth edge is sometimes damaged, easy to leak

7. The thread cannot see the luster, gray and poor hand feel,

8. The core is crooked, the wall thickness is uneven, and the fluid is easy to block after passing.

9. Roughly made, the surface is not treated, and it is easy to be oxidized

10. High carbon content, not corrosion-resistant, poor toughness, weak tensile strength.
