Glass Lined Coated Potable Water Storage Tank Comply With NSF61 Certification
Glass coating protect water tanks
The application of glass fused to steel tank is wide ,which has advantages in storing potable water and other liquid applications . In addition it is easy to do the assembly , have excellent acid and alkali proof , great service life , minimal maintenance cost comparing with other liquid storage tanks .
The physical properties of glass coating are especially used to municipal and industry applications , because the glass coatings form a hard , glossy , inorganic barriers for both interior and exterior tank wall resist of weather condition . The enamel frit burn in temperature from 800 -950 degree , creating greatest and strongest bond between enamel coating and steel .
Glass fused to steel tank has great corrosion , the steel surface can resist the acid and alkali PH from 3-11 . Glass fused to steel tank’s design comply with the standard AWWA D103 – 09 , OSHA , ect international standards , and the production line reach to the standard ISO 9001 – 2000 . For potable water storage , our steel sheet also have the NSF61 certification , which prove that the enamel coating is safe to contact the water directly .
