Plastic coated wire rope scrapping standard

1. Broken Wires

• Description: The appearance of broken wires, even in small numbers, indicates high stress on the wire rope. This could be due to improper installation or excessive wear.
• Actions: Identify the cause of damage. If the rope's length permits, remove the damaged section and reinstall the rope properly. If broken wires persist, the wire rope must be scrapped to ensure safety.

2. Decreased Diameter from Core Damage

• Description: A noticeable decrease in wire rope diameter often signifies damage to the fiber or steel core, or fractures in the internal strands of multi-layered ropes.
• Actions: Scrapping is necessary when the diameter reduction is due to core damage. Subtle damage, even if not immediately visible, can drastically reduce the rope’s strength. Conduct thorough internal inspections. If damage is confirmed, discard the wire rope.

3. External and Internal Corrosion

• Description: Corrosion is common in marine environments or areas with industrial pollution. It reduces the metal cross-sectional area, leading to a lower breaking strength. Corrosion can also cause surface roughness and accelerate fatigue cracking, potentially reducing the rope's elasticity.
• Actions: Regular inspection is crucial in corrosive environments. Severely corroded ropes must be scrapped to avoid potential failures.

4. Internal Wear and Pitting

• Description: Internal wear and pitting occur due to friction between strands and wires, particularly under bending stress. This friction weakens the rope over time.
• Actions: Inspect for signs of internal wear during regular maintenance. Replace the wire rope if wear or pitting compromises its structural integrity.

Notes:

• Regular maintenance and inspections are essential to prolong the life of wire ropes.
• Always follow the manufacturer’s guidelines and industry standards for wire rope inspection and replacement.
