Vitreous enamel, also called porcelain enamel, is a material made by fusing powdered glass to a substrate by firing, usually between 750 and 850 °C (1,380 and 1,560 °F). The powder melts, flows, and then hardens to a smooth, durable vitreous coating. It is an invaluable industrial process to coat steel for practical uses in appliances, cookware, and signage. In the 1800s, industrial enameling was developed to coat steel to keep it from rusting.
A metal sandwich barrel sleeve is welded to the outer wall of the tank liner, the barrel sleeve goes inside the antifreeze, the heat-conducting medium heated by the collector is circulated to the jacket layer and heated by conduction to the water inside the tank through the carbon steel plate, mainly used for balcony wall-hung natural circulation systems,or customize.
