Corrugated Tubes｜Causes of Brittleness and Cracking + 4 Fixes to Prevent Detachment

Corrugated tubes often become brittle, crack, or detach due to sunlight, heat, and vibration—posing risks in factory wiring systems. This article explains key causes and offers practical selection and installation tips to reduce failures.

■ Why Corrugated Tubes Fail in Industrial Environments
Corrugated tubes (สายร้อยสายไฟแบบลูกฟูก), also known as spiral conduits, are essential for protecting electrical wires in machinery, factory lines, and automotive systems. Yet, many factories face recurring issues:
・ Tubes become brittle and crack after prolonged use.
・ Tubes detach from mounting clips due to vibration.
・ Wires inside are exposed or damaged by heat or abrasion.
These problems compromise system safety, increase downtime, and raise maintenance costs.

■ 4 Common Causes of Corrugated Tube Degradation
1. UV Exposure: Outdoor use without UV protection leads to rapid tube deterioration.
2. Heat Buildup: Standard plastic tubes may deform or crack near engines, ovens, or welding stations.
3. Vibration: Inadequate fastening allows movement that wears out or detaches tubes.
4. Material Mismatch: Using PE tubes in oily or chemical-heavy zones causes faster breakdown.

■ 4 Solutions to Prevent Brittleness, Cracking, and Detachment
✅ Choose the Right Material:
・ PE (Polyethylene): Good for general use—flexible, impact-resistant.
・ PP (Polypropylene): Ideal for industrial use—resistant to heat and chemicals.
✅ Protect from Sunlight & Heat:
・ Use black UV-resistant tubes for outdoor or sunny areas.
・ Add heat-reflective sleeves in high-temperature environments.
✅ Secure Properly:
・ Keep clamp spacing within 30–50 cm.
・ Use lined clamps to minimize vibration and friction.
✅ Regular Maintenance:
・ Check tube condition and mounting clips every 3–6 months.
・ Replace worn sections and re-secure any loosened parts.
