Manual inspection PK wire rope NDT service

What are the defects of manual visual inspection compared with wire rope nondestructive testing services? Let's take a look with the editor!

1. Because the outer steel wire accounts for about 40% of the total metal cross-sectional area of the steel wire rope, only half of the area of these outer steel wires can be seen. Therefore, visual inspection and touch inspection only involve about 20% of the entire metal cross-sectional area. Visual inspection = 20% manual inspection + 80% estimated judgment.

2, internal defects manual detection can not be identified, there are potential risks.

3. Compared with wire rope nondestructive testing services, manual inspection cannot accurately quantify the degree of corrosion, especially internal corrosion, which cannot be judged.

4, wear, structural deformation, mechanical damage, loose wire, etc. are also unable to accurately identify and quantify.

According to the analysis of the whole rope breaking results of 8000 scrapped steel wire ropes by American research institutions, compared with the non-destructive testing service of steel wire ropes, the scrapped steel wire ropes under the condition of manual inspection are extremely dangerous: the breaking force is reduced by more than 30% (accident), accounting for about 2%;

Potential risks: the breaking force is reduced by more than 15% (accident hidden danger), accounting for about 10%;

Scrap state: breaking force reduced by 10%-15%, accounting for about 18%;

Safe state: the breaking force is reduced very little (waste of resources), accounting for about 70%.
