China Suppliers Factory Superior Corrosion Resistant Enamel Bolted Steel Tank for Sewage Water Storage
Description
The enamel bolted steel tank is a kind of bolted storage tank made from two materials: glass and steel. High-strength TRS (titanium-rich steel) plates and enamels are perfectly fused at high temperatures to form a highly inert inorganic glaze layer. This coating system has excellent anti-corrosion properties and is the best choice for sewage water storage.
Material Characteristics of Enamel Steel Tanks
Low Carbon, High Strength, High Titanium.
The steel substrate employed in the construction of glass-fused-to-steel tanks is a special high strength enamelled steel with a unique design and superior properties. Its mechanical properties, including yield strength, tensile strength, and elongation, far exceed those of conventional steel sheets.

Uses of Enamel Bolted Steel Tanks
Enamel bolted steel tanks are an ideal match for corrosive wastewater applications ranging from municipal sewage and industrial effluents to livestock wastewater and landfill leachate.
Enamel bolted tanks deliver outstanding performance for sewage & wastewater storage with these core merits:
- Molecular fused double-sided enamel coating provides superior anti-corrosion capacity, wide pH resistance (1–14), anti-abrasion against silt and H₂S corrosion, service life over 30 years without recoating.
- Smooth inert glass surface minimizes sludge adhesion and biofilm growth, lowering cleaning & maintenance downtime.
- Modular bolted assembly enables fast on-site installation regardless of weather, easy volume expansion, disassembly & relocation.
- Reliable rubber sealing prevents wastewater leakage and odor emission, compatible with membrane roof for closed sewage storage.
- Lower overall lifecycle cost vs welded steel or concrete tanks for municipal & industrial wastewater treatment projects.
Frequently Asked Questions
What is an enamel bolted steel tank?
It is a storage tank made by fusing glass and high-strength titanium-rich steel plates together at high temperatures. This creates an inert, highly anti-corrosive coating system ideal for wastewater and sewage storage.
What are the material characteristics of these tanks?
The tanks feature a low carbon, high strength, and high titanium steel substrate. Its yield strength, tensile strength, and elongation performance are superior to standard steel sheets.
What is the expected service life and pH resistance?
They have a service life of more than 30 years. The standard grade offers a pH range of 3 to 11, while the special grade can handle a wide pH range of 1 to 14.
What applications are enamel bolted steel tanks used for?
They are commonly used for corrosive wastewater applications, including municipal sewage, industrial effluents, livestock wastewater, and landfill leachate.
What are the benefits of their modular bolted construction?
The modular bolted design allows for fast on-site installation regardless of weather conditions. It also makes future volume expansion, disassembly, and relocation straightforward.
