The most important characteristic of porcelain enamel, from an industrial perspective, is its resistance to corrosion.Mild steel is used in almost every industry and a huge array of products; porcelain enamel is a very economic way of protecting this, and other chemically vulnerable materials, from corrosion. It can also produce very smooth, glossy finishes in a wide array of colours; these colours will not fade on exposure to UV light, as paint will. Being a fired ceramic, porcelain enamel is also highly heat-resistant; this allows it to be used in high-temperature applications where an organic anti-corrosion coating or galvanization may be impractical or even dangerous Porcelain enamel also sees less frequent employment of some of its other properties; examples are its abrasion resistance, where it may perform better than many metals; its resistance to organic solvents, where it is entirely impervious; its resistance to thermal shock, where it can resist rapid cooling from temperatures 500°C and higher; and its longevity. Based on above, the enamel steel tube is manufactured with the enamel which is developed by our company with the scientific formula and is evenly coated on the surface of the steel tube by the auto enamel tube production line. To use enamel tube as the heat exchange parts will be anti-abrasion and anti-corrosion, the surface is smooth and low cost of maintenance.
