Porcelain enamel fire water tank, Design Comply With NFPA-22 Product Introduction Porcelain enamel fire water tanks are also named as a glass-fused-to-steel tank or bolted steel tank, which combines the strength and flexibility of the steel with the corrosion resistance of the glass. After firing at 820°C-930°C high temperature, the molten glass reacts with the steel plate surface to form an inert and inorganic bond, which combines the strength and flexibility of steel and outstanding corrosion resistance of glass, so Glass-Fused-to-Steel tanks can provide many advantages over standard epoxy or weld painted storage tanks. Center Enamel's porcelain enamel fire water tanks engineering design meet or exceed AWWA D103-09 and EN/ISO28765:2011, and our fire water tank engineers make tank engineering calculation on each specific tank structure according to project local environmental conditions, such as snow load, wind speed, seismic zone, etc., to make sure the tank structure's adequate security in long-term service life.
