GLS tanks are Glass Lined Steel tanks, also known as Glass-Fused-to-steel tanks. The reason of fusing glass with steel is to enhance the properties of latter. Single Steel is vulnerable to environmental conditions, hence the fusion is required. After fusing the steel with glass, the strength increases, the acceptable bracket of PH value for alkaline solutions widens, and the resistance of abrasion inflates.
We also offer Glass-fused-tanks as per the RTP technology.
The tank panels are lined inside and outside with the glass enamel. The enamel is a solid, smooth and shiny cover of silicate. It is fused in a special furnace having temperature ranges from 780 to 900 degree Celsius. The Steel rounded (cylinder) shell of the tank is built from two-layer glass-fused sheet coated on both the sides. The sheets are attached with special high-grade bolts and sealed by constantly flexible silicones (sealants). The connecting material and shell accessories are equipped with the surface treatment. The glass-fused tanks can be used to store fluid or loose material. The tanks are also a fundamental building element of environmental technological facilities such as Waste Water Treatment, and Biogas Stations.
Every sheet is checked in the manufacturer’s plant for the enamel layer completeness by using the POROSCOPE (DEZ 4.13) and PINHOLE (DEZ 4.12) test according to DIN ISO 2746. The chemical resistance and physical properties are also tested according to DIN and they comply with the highest quality requirements according to the methodology by the German Enameller’s Association (DEZ).
Glass coated sheets can be delivered in four standard colors; Green (RAL 6009), Brown (RAL 8017), White (RAL 9000), and Blue (RAL 5013).
