Specification #GL 0195
GLASS (PORCELAIN ENAMEL) LINING SPECIFICATION

  • Hanson glass lining consist of a specially formulated sodium aluminum borosilicate composition which is finely ground, mixed with inert clays and other minerals, wet sprayed to a uniform depth on a sandblasted surface, and then fused to the steel vessel by firing at a temperature of not less than 1500ºF.
  • The glass lining process provides a hard inert barrier of silica glass chemically and mechanically bonded to the steel tank interior to provide excellent resistance to corrosion.
  • 25 grams per square foot of sacrificial anode(s) is/are supplied with every glass lined tank. They must be examined and cleaned or replaced to maintain protection and tank warranty.
