What are the principles for wire rope nondestructive testing and scrap determination? Let's learn about it together!

1. The number of broken wires on the surface reaches 10% of the total number of wires in the rope or 2 broken wires occur within one twist length. If the number of broken wires of steel wire rope lifting hot metal or dangerous goods reaches 5%, it will be judged as scrapped.

2. If there is obvious corrosion in the steel wire on the surface layer or inside of the steel wire rope, it will be judged to be scrapped.

3. If the wear of steel wire rope reaches 40% of the original wire diameter on the surface, it will be judged to be scrapped.

4. If the diameter of steel wire rope is reduced by 7% or the dimension core is increased by 5%, it will be judged as scrapped.

5. If the whole stock breaks or burns out, it will be judged as scrapped.

6. If the elongation of the local outer steel wire rope is "cage", it will be judged to be scrapped.

7, wire rope kink, extrusion, dead angle, hard bending, plastic deformation, hemp core out and other serious deformation is judged to be scrapped.

8, wire rope and joint parts crack or slip deformation, serious extraction, displacement and other extraction phenomenon is judged to be scrapped.
