Storage Tank Comparison
Structural Design
- Self-Bunded Tanks: Double-shell design with inner and outer shells forming a sealed interlayer space. Integrally molded structure without weak points.
- Ordinary Storage Tanks: Mostly single-shell structures relying on a single tank body. Simpler design with fewer protection layers, vulnerable to external damage.
Safety Protection
- Self-Bunded Tanks: Secondary sealing protection; leaks are contained in the interlayer. Monitoring devices enable timely warnings, comprehensively avoiding leakage risks.
- Ordinary Storage Tanks: Lack secondary protection structures. Corrosion or breakage likely leads to leakage, causing pollution, fire hazards, and other safety issues.
Applicable Scenarios
- Self-Bunded Tanks: Suitable for corrosive, flammable, explosive, and low-temperature environments. Meets high safety requirements in chemical, pharmaceutical, and new energy industries.
- Ordinary Storage Tanks: Suitable for non-corrosive, low-risk media like water and neutral solutions. Used in civilian and simple industrial scenarios with lower safety requirements.
Maintenance Costs
- Self-Bunded Tanks: Made of corrosion-resistant materials with stable structure. Routine maintenance involves periodic inspections and monitoring, resulting in low frequency and controllable long-term costs.
- Ordinary Storage Tanks: Susceptible to corrosion and environmental erosion, requiring frequent anti-corrosion and repair work. Maintenance is cumbersome and may cause production downtime, leading to higher overall costs.
Key Consideration
When selecting between tank types, assess the specific operational environment, safety requirements, and long-term maintenance implications. Self-Bunded Tanks offer enhanced protection for hazardous materials, while Ordinary Storage Tanks may suffice for benign substances in controlled settings.
