1
Impact of Media Corrosion
- The corrosivity of stored media is a core factor affecting tank service life.
- Acidic, alkaline, or chloride-containing media continuously erode the metal surface, causing pitting and uniform corrosion.
- High impurity content accelerates local corrosion rates, potentially leading to leaks and shortened equipment lifespan.
- Appropriate protective processes should be selected based on media characteristics to reduce corrosion impact.
2
Effect of Operating Temperature
- Operating temperature changes significantly impact the service life of carbon steel tanks.
- Prolonged high temperatures accelerate steel oxidation, reduce material toughness and strength, and cause creep deformation.
- Low temperatures may cause brittle transformation, making steel prone to cracking under external impact.
- Frequent temperature fluctuations cause thermal stress, leading to weld fatigue damage and shortening equipment lifespan.
3
Manufacturing and Installation Quality
- Quality control during manufacturing and installation directly determines the foundational service life of storage tanks.
- Improper steel selection and insufficient processing precision can result in inherent performance defects.
- Non-standard welding processes can lead to slag inclusions and porosity, creating stress concentration points.
- Inadequate installation leveling causes uneven stress distribution, leading to structural deformation and accelerated wear.
4
Daily Operation and Maintenance Level
- Standardized daily operation and maintenance are crucial for extending tank service life.
- Delayed periodic inspections prevent early detection of corrosion and leakage issues.
- Inadequate maintenance of protective layers accelerates tank corrosion rates.
- Improper operations like overpressure and overtemperature exacerbate equipment wear and performance degradation.
