China GFS Tanks for Sludge Storage - Durable Solutions from Leading Suppliers & Factory
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 type of bolted storage tank constructed from titanium-rich steel (TRS) plates and enamels. They are fused at high temperatures to create an inert inorganic glaze layer, offering the structural strength of steel combined with the outstanding corrosion resistance of glass.
Why are GFS tanks ideal for sludge and mud storage?
Sludge contains abrasive and highly corrosive substances like sand, salts, acids, and microbes. GFS tanks feature excellent anti-corrosion, wear resistance, and high-performance seals, making them exceptionally durable against chemical wear and odors.
How long does the installation of GFS bolted tanks take?
One of the main advantages of GFS bolted tanks is rapid installation. For instance, a project consisting of three 500m³ tanks can be successfully installed in as little as 5 days.
What is the lifespan and maintenance requirement for GFS tanks?
GFS tanks require very simple maintenance and offer a long service life exceeding 30 years due to their robust double-sided glass-fused coating and corrosion-resistant bolted joints.
Can GFS tanks be expanded or relocated?
Yes, because GFS tanks are modular and bolted, they offer excellent flexibility. They can easily be expanded, relocated, or recycled as operational needs change.
How does the GFS tank design prevent subway shield slurry leakage?
Subway slurry has high viscosity and high sand content. LIDA uses a design where the storage tank is directly secured to the ground via reinforcing stiffeners, taking advantage of the slurry's high viscosity to prevent leakage without needing complex foundations.
