GFS Tanks for Municipal Wastewater Project
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. This coating system has excellent anti-corrosion properties and is the best choice for municipal wastewater treatment project.
Municipal wastewater is a complex mixture characterized by large volume, relatively consistent water quality, good biodegradability, but containing suspended solids, nitrogen and phosphorus, microorganisms, and potentially corrosive gases. GFS bolted tanks have become a classic choice for municipal wastewater storage tanks because their electroplated enamel surface can perfectly solve corrosion, vapor phase corrosion, and coefficient wear simultaneously, and is smooth and not prone to scaling.
Glass fused to steel is a permanent, molecular bond created by fusing a specially formulated silica-based glass enamel to a base sheet of steel at very high temperatures (around 820°C / 1500°F), combines the advantages of both materials -- the strength and flexibility of steel and excellent anti-corrosion properties of glass.
Material Characteristics of Glass-Fused-to-Steel Tanks
-Low Carbon, High Strength, High Titanium.
The steel substrate employed in the construction of glass-fused-to-steel tanks is a special high strength enamelled steel with a unique design and superior properties. Its mechanical properties, including yield strength, tensile strength, and elongation, far exceed those of conventional steel sheets.
