??? What Causes Tube Failures?

1. Corrosion ??: Exposure to corrosive fluids can degrade materials over time.
2. Fouling ??: Build-up of dirt, biofilms, or chemical deposits reduces efficiency.
3. Thermal Fatigue ??: Repeated heating and cooling cycles weaken the material.
4. Erosion ?: High-velocity fluids cause mechanical wear.

?? Solutions for Prevention

?? Routine Inspections: Regular NDT (Non-Destructive Testing) to catch issues early. ?? Proper Cleaning: Schedule chemical or mechanical cleaning to prevent fouling. ?? Material Upgrades: Use corrosion-resistant alloys or coatings where needed. ??? Optimize Flow Rates: Prevent erosion with better flow management. ?? Monitoring Systems: Install sensors to track temperature, pressure, and flow.

?? Spotlight: Common Causes of Failure

1?? Corrosion: Chemical reactions weaken tube material. ?? Prevention Tip: Use corrosion-resistant alloys and apply protective coatings.

2?? Erosion: High-velocity fluids cause wear and tear. ?? Prevention Tip: Optimize flow rates and use hardened materials.

3?? Thermal Fatigue: Frequent temperature changes lead to cracks. ?? Prevention Tip: Improve operational procedures to minimize sudden temperature shifts.
