Corrosion & Aging Prevention
Scientific protection strategies to extend service life — safeguarding metal surfaces against environmental erosion
Surface Coating Protection
- High-performance anti-corrosion coatings applied on external walls — UV‑resistant & chemically inert formulations.
- Thorough surface preparation — rust removal, degreasing, and cleaning ensure maximum coating adhesion.
- Barrier against moisture & oxygen — isolates metal from aggressive atmospheric agents.
- Regular patch repair — immediate fixing of damaged paint prevents rust propagation and preserves structural aesthetics.
Cathodic Protection Technology
- Sacrificial anodes or impressed current — turns the tank bottom into a cathode, drastically reducing oxidation.
- Ideal for buried sections & humid zones — protects areas most vulnerable to electrochemical corrosion.
- Regular potential monitoring — ensures uniform current distribution and optimal protection level.
- Extends asset lifespan — proven technique for below‑grade tank bottoms and ring walls.
Environmental Humidity Control
- Ventilation & dehumidification systems — maintain dry, circulating air in storage premises.
- Prevent surface condensation — reduces moisture retention time, eliminating a key corrosion driver.
- Relative humidity thresholds — keeping RH below 50% drastically slows electrochemical corrosion rates.
- Atmospheric control — minimizes hygroscopic salt deposition and dew formation on tank exteriors.
Regular Inspection & Maintenance
- Thickness gauging & ultrasonic testing — quantifies wall loss and detects weld cracks at early stage.
- Bottom sediment & water removal — prevents localized under‑deposit corrosion from escalating.
- Systematic repair protocol — immediate correction of anomalies ensures continuous integrity.
- Risk-based inspection (RBI) — schedules non‑destructive tests to maximize reliability and minimize downtime.
