Description
Bolted Tanks are modular, factory-manufactured storage tank systems assembled on site using high‑strength bolted connections. They are widely used in municipal, industrial, and environmental engineering projects where large storage capacity, fast installation, and long service life are required.
Compared with traditional welded tanks or concrete structures, bolted tanks offer superior construction flexibility, controlled manufacturing quality, and lower total lifecycle cost. Panels are prefabricated under strict quality control, transported efficiently, and assembled at the project site without heavy civil works, making them ideal for remote locations or fast‑track projects.
Our Bolted Tanks product line covers a wide range of materials and configurations, including Glass‑Fused‑to‑Steel (GFS) Tanks and Epoxy‑Coated Steel Tanks, enabling optimal solutions for different media, corrosion environments, and budget requirements.
Key Advantages
- Modular & Scalable Design–Tank capacity can be expanded or reduced by adding or removing panels.
- Fast On‑Site Installation–Short construction period with minimal site disruption.
- Factory‑Controlled Quality–Steel panels are manufactured and coated under controlled conditions.
- Flexible Transportation–Flat‑packed panels reduce shipping volume and cost.
- Wide Application Range–Suitable for water, wastewater, sludge, chemicals, and industrial liquids.
- Long Service Life–Designed for long‑term operation with low maintenance requirements.
Typical Applications
Bolted Tanks are commonly applied in:
- Municipal water storage and wastewater treatment projects
- Industrial process water and cooling water storage
- Sludge thickening and sludge storage systems
- Chemical and industrial liquid storage
- Environmental protection and energy projects
Tank Materials & Coating Options
- Glass‑Fused‑to‑Steel (GFS) Bolted Tanks
A durable coating formed by fusing glass to steel at high temperature, providing excellent corrosion resistance and chemical stability.
- Epoxy‑Coated Steel Bolted Tanks
Steel panels coated with advanced epoxy systems, offering a cost‑effective solution for moderate corrosion environments.
