Corrosion-Resistant FBE Tanks for Wastewater Treatment - China Suppliers & Factory
Description
The epoxy coated steel bolted tanks are made of steel panel which coated with the fusion bonded epoxy internally and externally. High-strength bolts were used for on-site connection and sealing assembly, so that it can achieve efficient corrosion protection and rapid construction, and is widely used in the field of wastewater treatment.
The epoxy coated bolted steel tank is mainly consisted of steel panel that has been internally and externally coated with a layer of epoxy-based protective paint. Fusion bonded epoxy is an electrostatically applied coating system with superior coverage and uniform coating thickness.

Advantages of Epoxy Coated Steel Tanks
🛡️ Excellent Corrosion Resistance
Resists corrosion from a wide range of acids, alkalis, salts, organic solvents and oxidizing agents — ideal for chemical, electroplating, and pharmaceutical industries. Not easily aged or degraded in complex chemical environments, resulting in a long service life.
💪 High Mechanical Strength & Wear Resistance
Epoxy resin exhibits high hardness, favorable impact resistance and compressive strength, capable of bearing external mechanical loads. Endures corrosion from diverse acids, alkalis, salts, and solvents — suitable for storing corrosive media across multiple industries.
🔒 Excellent Sealing & Leak-Proof Performance
Integral winding or casting processes eliminate weld seams or gaps, removing leakage risk. Combined with high-performance seals, volatile or hazardous substances are fully contained.
⚡ Lightweight & Easy to Install
Weighs significantly less than steel or concrete tanks of the same volume, reducing transportation and installation costs. Modular design allows on-site assembly, adaptable to large or special site requirements.
⚙️ Excellent Insulation Properties
Non-conductive properties make it suitable for electronics and power industries, including insulating oil and electrolytes. Anti-static function can be achieved by adding conductive materials, suitable for flammable and explosive environments.
🔧 Flexible Customization & Adaptability
Vertical, horizontal, and irregularly shaped structures can be customized for different spaces. Can be composited with fiberglass (FRP) or modified resin to further improve temperature and pressure resistance.
💰 Low Maintenance Costs
No regular anti-corrosion coating required, unlike metal storage tanks. The smooth inner wall prevents material buildup, making cleaning simple and reducing residue.
🌿 Environmental Protection & Safety
Food-grade epoxy resin is suitable for storing drinking water and food additives. Flame retardant performance can be obtained via formula modification to satisfy fire safety standards and requirements.
Uses of Epoxy Coated Steel Tanks
Epoxy coated steel tanks are used in a wide range of industries for their durability, corrosion resistance and versatility. They are often used in applications requiring moderate corrosion resistance and lower cost:
- 🫙 Edible / Vegetable Oils
- 📦 Dry Bulk Solids
- 🌾 Farm Digesters
- 🔥 Fire Water
- 💧 Potable Water
- 🔵 Filter Tanks
- 🏙️ Municipal Sludge Storage / Treatment
All applications must take chemical concentration and temperature into account. All specifications apply only to the contact surfaces. Detailed specifications can be provided upon request.
Overall, epoxy coated steel tanks represent a durable, long‑lasting and corrosion‑resistant solution for water storage. They adapt to diverse application scenarios and come in multiple sizes to satisfy the specific requirements of different projects.
Frequently Asked Questions
Q What is fusion bonded epoxy (FBE) coating and how is it applied to steel tanks?
Fusion bonded epoxy (FBE) is an electrostatically applied powder coating system. The steel panels are pre-heated, and the epoxy powder is sprayed onto the surface where it melts and bonds to form a uniform, continuous protective layer — both internally and externally. This process ensures superior coverage and consistent coating thickness, typically ranging from 80 to 450 microns.
Q What pH range can epoxy coated steel tanks handle?
Standard grade epoxy coated steel tanks can handle a pH range of 3 to 11, making them suitable for mildly acidic to moderately alkaline environments. For more demanding applications, special grade tanks are available to handle a pH range of 1 to 14, covering highly acidic and highly alkaline conditions.
Q How long is the service life of an epoxy coated bolted steel tank?
Epoxy coated bolted steel tanks are designed for a service life of more than 15 years under normal operating conditions. Their longevity depends on the stored medium, operating temperature, and proper maintenance. Because no regular anti-corrosion recoating is required, overall lifecycle costs remain low.
Q Are epoxy coated steel tanks suitable for drinking water storage?
Yes. Food-grade epoxy resin formulations are available and are suitable for storing potable (drinking) water and food additives. These formulations are non-toxic and environmentally friendly, meeting relevant food safety and water quality standards. Always confirm the specific grade and certification with the manufacturer for your application.
Q How are epoxy coated bolted steel tanks assembled on-site?
Epoxy coated bolted steel tanks use a modular panel system. Pre-coated steel panels are transported to the installation site and assembled using high-strength bolts along with high-performance sealing materials. This bolted construction method enables rapid on-site assembly, minimizes heavy equipment requirements, and makes the tanks adaptable to locations with limited access or unusual site conditions.
Q Can epoxy coated steel tanks be customized in size and shape?
Yes. Epoxy coated bolted steel tanks offer flexible customization in terms of capacity, diameter, height, and configuration — including vertical, horizontal, and other structural forms. They can also be composited with fiberglass (FRP) or modified resin linings to further enhance temperature and pressure resistance, meeting the specific requirements of different industrial and municipal projects.
