Glass Fused to Steel (GFS) Sewage Tanks Durable and Corrosion-Resistant Storage tanks Solutions for Wastewater Treatment

Sewage tanks are critical components in wastewater management, designed to safely contain and treat sewage before it is released or further processed. Shijiazhuang Zhengzhong Technology Co., Ltd, operating under the brand Center Enamel, leverages pioneering Glass Fused to Steel (GFS) technology to manufacture sewage tanks known for their outstanding corrosion resistance, durability, and cost-effectiveness. This article elaborates on the features, benefits, applications, construction, and technological advantages of Center Enamel’s GFS sewage tanks, positioning them as an industry leader in environmental storage solutions.

Understanding Glass Fused to Steel Technology

Glass Fused to Steel involves fusing a molten glass enamel coating onto steel tank plates at temperatures between 820°C and 930°C. This process creates a monolithic layer firmly bonded to the steel surface that combines the mechanical strength and flexibility of steel with the superior corrosion and abrasion resistance of glass.

The resulting GFS tanks offer a smooth, inert, non-porous interior that is highly resistant to aggressive sewage components and environmental factors. The glass enamel coating acts as a protective barrier preventing corrosion, reducing maintenance needs, and extending tank service life beyond 30 years.

Why Choose GFS Sewage Tanks?

Sewage and wastewater environments are among the most corrosive for storage tanks, due to acidic and alkaline compounds, biological activity, and abrasive solids. Traditional materials such as carbon steel or concrete can suffer from deterioration, leakage, and costly repairs over time. GFS sewage tanks address these challenges comprehensively:

• Superior Corrosion Resistance: The strong glass enamel coating protects steel from harsh chemicals and acidic sewage fluids, avoiding rust and pitting.
• Abrasion and Impact Resistance: The hard enamel surface withstands abrasive solids and external mechanical stresses.
• Gas and Liquid Impermeability: The fused glass surface prevents permeation and leaks, ensuring containment integrity.
• Smooth and Cleanable Interior: Resistant to bacterial growth and easy to maintain hygiene.
• Thermal Stability: Retains structural integrity under temperature fluctuations typical in sewage treatment.
• Modular Assembly: Bolted panel design facilitates faster, safer installation and future expansion or relocation.

Technical Specifications and Quality Standards

Center Enamel's GFS sewage tanks are manufactured to meet stringent international standards including AWWA D103-09, ISO 28765, NSF/ANSI 61, OSHA, and NFPA. Key technical highlights include:

• Coating Thickness: 0.25 - 0.45 mm glass enamel layer
• Steel Plate Thickness: 3 mm to 12 mm depending on tank size and design
• Color Options: Black blue, grey olive, forest green, cobalt blue, desert tan
• Service Life: Minimum of 30 years under normal operating conditions
• PH Range: Standard tanks suit pH 3-11; custom variations can withstand pH 1-14
• Adhesion Strength: 3450 N/cm² to guarantee solid bonding of glass and steel
• Hardness: 6.0 Mohs scale, ensuring tough impact tolerance
• Holiday Test: >1500V to detect and eliminate coating imperfections

All tanks undergo rigorous quality control including impact resistance testing, spark testing for coating integrity, chemical corrosion resistance, and dimensional inspection to ensure perfect assembly fit and sealing reliability.

Design and Structural Features

• Modular Bolted Tanks: Panels are precision manufactured, coated, and bolted onsite, reducing installation time, costs, and dependency on welding or heavy machinery.
• Conical or Flat Bottoms: Designed to aid sediment collection or complete discharge, depending on application.
• Manholes and Access Doors: Facilitates inspection, maintenance, and sludge removal.
• Safety Features: Pressure/vacuum relief valves, level indicators, venting systems, and platforms for safe access.
• Customization: Tank size, color, coating formulations, and accessories customized per client and project needs.
