Corrosion-Resistant FBE Tanks for Wastewater Treatment - China Suppliers & Factory Quality Epoxy Coated Solutions
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
Excellent chemical resistance: It resists corrosion from a wide range of acids, alkalis, salts, organic solvents and certain oxidizing agents, making it ideal for the storage of corrosive media in chemical, electroplating, pharmaceutical and other industrial applications.
Long-term stability: It is not easily aged or degraded in complex chemical environments, resulting in a long service life.
High Mechanical Strength & Wear Resistance
Sturdy construction: Epoxy resin exhibits high hardness, favorable impact resistance and compressive strength, and is capable of bearing certain external mechanical loads.
Superior chemical resistance: It can endure corrosion caused by diverse acids, alkalis, salts, organic solvents and several oxidizing agents, thus being suitable for storing corrosive media in industries including chemical, electroplating and pharmaceutical.
Excellent Sealing & Leak-Proof Performance
Seamless molding: Often uses integral winding or casting processes, with no weld seams or gaps, eliminating the risk of leakage.
Sealing design: Combines high-performance seals to ensure no leakage of volatile or hazardous substances.
Lightweight, High-Strength & Easy to Install
Lightweight: Weighs significantly less than steel or concrete tanks of the same volume, reducing transportation and installation costs.
Modular design: Partially assembleable on-site, adaptable to large or special site requirements.
Excellent Insulation Properties
Good electrical insulation: It features non-conductive properties, making it suitable for special storage scenarios in the electronics and power industries, including insulating oil and electrolytes.
Anti-static design: Anti-static function can be achieved by adding conductive materials, suitable for flammable and explosive environments.
Flexible Customization & Adaptability
Flexible shape and size: Vertical, horizontal, and irregularly shaped structures can be customized to suit different spaces.
Reinforced lining: Can be composited with fiberglass (FRP) or modified resin to further improve temperature and pressure resistance.
Low Maintenance Costs
No anti-corrosion coating needed: Different from metal storage tanks, it does not require regular application of protective corrosion coatings.
Easy cleaning: The smooth inner wall prevents material buildup, making cleaning simple and reducing residue.
Environmental Protection & Safety
Non-toxic and environmentally friendly: Food-grade epoxy resin is suitable for storing drinking water and food additives.
Flame Retardant Option: Flame retardant performance can be obtained via formula modification, so as 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 (FAQ)
Q1
What are epoxy coated steel bolted tanks made of?
They are constructed from high-grade steel panels coated with fusion bonded epoxy (FBE) both internally and externally. The panels are assembled on-site using high-strength bolts and specialized sealing systems.
Q2
What is the expected service life and pH resistance of these tanks?
Epoxy coated steel tanks have an expected service life of more than 15 years. Their pH resistance ranges from pH 3~11 for standard grades and pH 1~14 for special grade applications.
Q3
Can epoxy coated bolted steel tanks be used for drinking water storage?
Yes. Non-toxic, food-grade epoxy resin coatings are environmentally friendly and certified safe for storing potable drinking water as well as food additives.
Q4
What maintenance is required for epoxy coated tanks?
They have low maintenance costs because they do not require periodic re-application of protective anti-corrosion coatings. In addition, their smooth inner surface prevents residue buildup and facilitates easy cleaning.
Q5
Why are epoxy bolted steel tanks preferred for on-site construction?
Their lightweight and modular panel design significantly lowers transportation expenses and allows for fast, flexible assembly on-site, easily adapting to specific site constraints and sizes.
Q6
What media and liquids can be stored in these tanks?
They are widely used for potable water, fire water, wastewater and municipal sludge treatment, farm digesters, edible/vegetable oils, dry bulk solids, and various chemical/industrial solutions.
