China Suppliers Factory for Bolted GFS Tanks - Durable Sludge Storage Solutions with Corrosion Resistance
Description
The Glass Fused to Steel (GFS) 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. Based on the coating technology, it combines the advantages of both materials — the strength and flexibility of steel and excellent anti-corrosion properties of glass.
Sludge storage tanks' requirements are different from the different application. For sewage water treatment, the storage tanks pay more attention to corrosion prevention, heat preservation, and extending service life. For subway sludge, oil drilling and other fields, it places greater emphasis on wear resistance, explosion prevention, and rapid relocation.
Why Choose Us
LIDA's glass fused to steel (GFS) bolted tanks are the classical choice for sludge/mud storage. They are composed mainly of enamel panel, special sealant and self-locking bolts, etc. The steel plates are overlapped, bolted together and sealed with high performance seals. All the bolt heads are plastic-capped to provide protection against corrosion in the process environment. Mastic is extruded between the panels and the bolt heads seal the bolt shank to prevent contact with process fluids.
Sludge often contains sand, salt, acidic and alkaline substances, and microbial metabolic products, which can easily cause wear and corrosion to the tank. Meanwhile, sludge may produce odors, leachate, and harmful gases during storage, and must meet environmental protection requirements. GFS tanks are an ideal choice to meet all the requirements.

The Design of Subway Sludge Storage Tank
Subway slurry (mainly shield slurry) is a fluid formed by mixing rock and soil with water, bentonite, foam and other additives during shield tunneling. The core characteristics are high sand content and high viscosity. LIDA employs a design where the storage tank is directly fixed to the ground via reinforcing stiffener. Once the sludge accumulates in the storage tank, it won't leak out from the cracks without foundation as its high viscosity.

Frequently Asked Questions
❓What is a Glass Fused to Steel (GFS) tank?
A Glass Fused to Steel (GFS) tank is a bolted storage tank that combines high-strength TRS (titanium-rich steel) plates with glass enamel, fused together at high temperatures to form a highly inert inorganic glaze layer. This technology merges the structural strength of steel with the excellent corrosion resistance of glass.
❓Why are GFS tanks suitable for sludge storage?
Sludge typically contains sand, salt, acidic and alkaline substances, and microbial metabolic products that cause wear and corrosion. GFS tanks provide outstanding resistance to these harsh conditions while also meeting environmental requirements by preventing odors, leachate, and harmful gas emissions during storage.
❓How long is the service life of a GFS tank?
GFS tanks are engineered for long-term durability. With simple and routine maintenance, they have a service life in excess of 30 years, making them a highly cost-effective solution for sludge and liquid storage applications.
❓How quickly can a GFS bolted tank be installed?
One of the key advantages of GFS bolted tanks is their fast installation. As demonstrated in the Beijing subway slurry project, three tanks with a volume of 500m³ each were fully installed in just 5 days. The modular bolted design significantly shortens the construction period compared to traditional welded tanks.
❓Can GFS tanks be relocated or expanded after installation?
Yes. GFS bolted tanks are highly flexible — they can be dismantled, relocated, and reassembled at a new site with minimal effort. They also support capacity expansion by adding additional panels, making them ideal for projects with changing storage needs such as subway construction and oil drilling operations.
❓What makes LIDA's GFS tanks suitable for subway slurry storage specifically?
LIDA's GFS tanks for subway slurry storage feature a unique design where the tank is directly fixed to the ground via reinforcing stiffeners, eliminating the need for a traditional foundation. Because shield slurry has high viscosity and high sand content, this design effectively prevents leakage while enabling rapid deployment and relocation across active construction sites.
