What is Glass lining?

‘Glass Lining’ is an internationally renowned technology in solar water heating systems to help corrosion of solar water inner tank and provide clean hot water. As we are aware when corrosion strikes, almost nothing escapes. Corrosion affects most kind of metal surfaces especially in solar water heating systems; it can affect the inside of the tank. This happens in areas that have hard water. Hard water has chloride content that can even corrode tanks of stainless steel material.

Glass lining is a combination of three processes. Production of powdered glass, metal fabrication, and combining the glass and metal. It is non-stick coating created by fusing powder glass to an inner surface of the metal tank by firing between 850 °C to 870 °C in an automatic furnace resulting in a coating that melts, flows, and then hardens to a smooth, durable glass coating on the metal surface. So that glass and metal cannot be separated from each other. Glass lining provides superior longevity to the hot water tank. In certain areas, stainless steel tanks tend to fail more rapidly than glass lined tanks due to chlorides in the water.
