In-depth analysis of international benchmark cases, cost optimization formulas and future trends of zero-carbon aluminum, and now explore the new "aluminum" process of chemical containers!
International application scenarios
1. Chemical storage and transportation
European Hydrochloric Acid Storage Tank (BASF, Germany): 3003 aluminum plate lined with PTFE coating, resistant to 30% HCl (40°C), with a life of 20 years and a 50% reduction in maintenance costs.
North American liquid chlorine shipping tank: anodized surface treatment, passed the NACE TM0177 hydrogen sulfide corrosion test, replacing stainless steel and reducing costs by 35%.
2. Petrochemical energy
Middle East Crude Oil Separator (Saudi Aramco): sulfide resistant (H₂S>1000ppm), salt spray > 3000 hours (ISO 9227), 60% less cost than titanium.
Australian LNG storage tank: -162°C low temperature crack resistance, weld impact energy ≥ 30J (EN ISO 148-1).
3. Environmental protection and pharmaceuticals
Japan's nuclear wastewater treatment tank: resistant to radiation oxidation, passed IAEA nuclear grade certification, and the life cycle is extended to 30 years.
Pharmaceutical reactor in India: Epoxy coating meets FDA 21 CFR standards and is resistant to 50% NaOH solution.
Core Advantages: Corrosion Resistance and Cost Reduction "Double Engine"
Corrosion-resistant crushing
3 times higher corrosion resistance: Compared with 1000 series pure aluminum, 3003 aluminum coil salt spray test > 3000 hours (ISO 9227), and the pitting resistance is increased by 200%.
Broad-spectrum media resistance: Suitable for pH 2-12 environment (10% H₂SO₄, 40% NaOH), passed ASTM G31 acid immersion test.
Lifecycle cost optimization
Lightweight and weight reduction: the density is 2.73g/cm³, which is 50% lighter than stainless steel containers and 30% less energy consumption for transportation.
Maintenance-free design: the coating life is > 15 years, and the comprehensive cost is 40% lower than that of FRP.
Green manufacturing compatibility
100% recyclable, carbon emissions 95% lower than primary aluminum (Hydro CIRCAL technology).
Comply with the EU CBAM carbon tariff standard (carbon footprint<4tCO₂e/ton) to avoid trade barriers.
Future Trend: Technology Iteration and Market Explosion
