Chemical Storage FBE Bolted Tanks: Safeguarding Hazardous Liquids with Zero-Leak Technology
Discover how FBE-coated bolted tanks store aggressive chemicals safely for decades. Compliant with ASME, API 650, and REACH standards.
Chemical manufacturing and processing industries lose $12 billion annually due to storage tank failures, per the American Chemical Council (2023). Traditional solutions like rubber-lined or stainless steel tanks struggle with:
- Permeation Leaks: Organic solvents diffuse through polymer liners.
- Stress Corrosion Cracking (SCC): Chlorides in HCl or NaClO degrade stainless steel welds.
- Thermal Degradation: Thermal cycling (-50°C to 200°C) delaminates coatings.
FBE (Fusion-Bonded Epoxy) bolted tanks overcome these risks through non-porous molecular barriers and modular, crevice-free designs, making them the gold standard for sulfuric acid, caustic soda, and VOC storage.
Engineering Excellence: How FBE Bolted Tanks Work
Tank Architecture & Materials
- Panels: ASTM A516 Gr.70 carbon steel (ultimate tensile strength 70 ksi) coated with 80-200 μm FBE.
- Coating Process:
- Surface Prep: Abrasive blast-cleaned to Sa 2.5 (ISO 8501-1).
- Electrostatic Spray: 95% transfer efficiency ensures zero holidays.
- Thermal Cure: 200°C curing forms cross-linked epoxy matrix.
- Bolting System: 316L stainless steel bolts with FFKM gaskets (Chemraz® 505 for pH 0-14).
