Glass Fused to Steel (GFS) Slurry Tanks : Durable, Corrosion-Resistant Storage Solutions for Industrial Slurry Management

Glass Fused to Steel (GFS) Slurry Tanks : Durable, Corrosion-Resistant Storage Solutions for Industrial Slurry Management

In industries such as mining, drilling, environmental protection, and construction, slurry is a challenging material to handle due to its chemical aggressiveness, abrasive nature, and potential environmental hazards. Effective, durable storage of slurry is critical for operational safety, efficiency, and regulatory compliance. Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel), as a global leader in bolted steel tank manufacturing, offers Glass Fused to Steel (GFS) slurry tanks engineered to meet these demands with superior corrosion resistance, longevity, and cost-effectiveness.

What Are Glass Fused to Steel Slurry Tanks?

Glass fused to steel slurry tanks are constructed from steel panels coated with a high-strength glass enamel fused at high temperatures to form a tough, inert, non-porous surface. This innovative composite material brings together the mechanical strength of steel with the chemical and abrasion resistance of glass, making it uniquely suited for storing chemically aggressive, abrasive slurries over extended periods.

The glass coating is bonded permanently to both interior and exterior surfaces of the steel panels via a controlled firing process, creating a seamless barrier that prevents corrosion, chemical attack, and wear.

Manufacturing Process

Center Enamel employs an advanced multi-step manufacturing process:

• Steel Plate Preparation: High-tensile titanium-enriched steel sheets are precisely cut and shaped, then prepared by shot blasting for optimal surface adhesion.
• Glass Slurry Application: A proprietary glass enamel slurry is evenly sprayed on both sides of steel plates.
• High-Temperature Fusion: The coated plates undergo firing at approximately 820-930°C in specialized kilns, fusing the glass to the steel to form an ultra-hard coating.
• Quality Checks: Panels are rigorously tested for coating thickness, uniformity, impact resistance, adhesion strength, and electrical holiday testing to ensure surface integrity.
• Panel Fabrication and Logistics: The high-quality coated panels are drilled, bolted, and sealed with chemical-resistant gaskets for modular, efficient on-site assembly.

This state-of-the-art process guarantees GFS slurry tanks with a service life surpassing 30 years in demanding industrial environments.

Advantages of GFS Slurry Tanks

Superior Corrosion Resistance

Slurry materials often contain acids, alkalis, salts, and particulate solids that can rapidly degrade other tank materials. The glass fused enamel provides a chemically inert barrier that resists corrosion across a wide pH range (typically pH 3-11, with special coatings handling pH 1-14), protecting the steel substrate from aggressive substances.

Outstanding Abrasion and Impact Resistance

The hard enamel coating on GFS tanks withstands abrasive solids typically found in slurries, reducing maintenance and prolonging tank life. The composite structure also endures mechanical impact, thermal shock, and pressure fluctuations without compromising tank integrity.

Hygienic and Easy to Maintain

The smooth, non-porous glass surface inhibits bacterial growth and accumulation of deposits, facilitating routine cleaning and minimizing contamination risks.

Modular and Quick to Install

Center Enamel’s bolted panel design allows rapid, cost-effective assembly onsite without welding, heavy machinery, or hot works permits — reducing safety risks and downtime. Tanks can be customized in size and shape to meet specific site constraints and capacity requirements.

Wide Chemical Compatibility

Glass fused to steel slurry tanks resist a broad range of chemicals, including organic solvents, water treatment chemicals, and aggressive industrial fluids, making them suitable for diverse slurry types.

Technical Specifications

Center Enamel’s GFS slurry tanks adhere to international standards such as ISO 28765 and AWWA D103, with typical specs including:

• Glass Coating Thickness: 0.25 - 0.45 mm for optimal durability.
• Steel Thickness: Ranges from 3 mm to 12 mm depending on tank size and slurry type.
• Coating Hardness: 6 Mohs hardness standard for abrasion resistance.
• pH Range: Typically pH 3-11; optional coatings handle extreme pH values.
• Service Temperature: Up to 140°F (60°C).
• Holiday Testing: >1500 V to detect micro-defects.
• Color Options: Custom color coatings for identification and branding.

Applications

• Mining and Mineral Processing: Storage of tailings slurry, flotation concentrates, and reagent slurries.
• Oil and Gas Drilling: Drilling mud containment with high abrasion resistance.
• Environmental Engineering: Containment of contaminated groundwater, leachate, and slurry in remediation projects.
• Chemical Processing: Holding tanks for chemically aggressive industrial slurries.
• Construction: Storage for slurry used in slurry walls, grouting, and excavation.
• Wastewater Treatment: Sedimentation tanks and sludges processing containment.

Environmental and Economic Benefits

Glass fused to steel slurry tanks minimize environmental risks by preventing leaks and contamination through their impermeable coatings. The longevity of the tanks reduces the frequency of replacements and repairs, lowering the overall project lifecycle costs. Installation efficiency and low maintenance also contribute to economic savings.

Global Presence and Trust

Center Enamel has supplied GFS slurry tanks to over 100 countries, trusted for their reliable performance in harsh industrial environments. Projects span continents and industries where stringent standards for sewage, chemical storage, and slurry handling are demanded.

Installation and Maintenance

Due to the modular panel design, installation is straightforward and faster than welded or concrete tanks. Proper foundation engineering and skilled assembly personnel are essential. Routine inspections and cleaning ensure optimal tank performance, with damaged panels replaceable without full tank disassembly.
