NSF / ANSI 61 Standard Potable Water Tanks For Government Drinking Water Projects
Potable water, commonly referred to as drinking water, can safely be stored by glass fused to steel bolted potable water tank. Our potable water tanks are designed and manufactured to NSF/ ANSI 61 standards. All our potable water tanks engineering design meet or exceed AWWA D103-09 and EN/ISO28765:2011, and our GFS 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.
Glass Fused to Steel Potable Storage Tanks
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. Glass-Fused-to-Steel technology is the premium coating technology in the storage tanks market, and Glass-Fused-to-Steel tanks are widely used in bio-energy, municipal sewage, landfill leachate and industrial wastewater treatment etc. applications

Quality Control of Fire Sprinkler Water Storage Tanks
1. Raw materials testing in the factory: ingredient analysis, impurities test.
2. Recipe finalized small samples test : enamel fluidity test, chromatic difference analysis, enamel burning experiment, acid and alkali resistance testing, glossy, adhesion etc,
3. Middle stage products test: amplification experiment simulated environment;
4. Destructive testing, detection, impact test, 1500 V holiday test, sliced electric microscope analysis.
