Bolted GFS Sludge Storage Tanks from China Suppliers and Factory for Corrosion Resistance and Durability
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.
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.

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.
