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.
|Average Minimum Thickness: (ASME)||5 - 12 mils|
|Adhesion:||Over 5000 psi|
|Abrasive Resistance:||5.4 mg/min (PEI test)|
|Tank Sizes:||30" OD to 78" OD Overall length to 336"|
|Color:||Dark (cobalt) blue|
|Anodes:||One or more 1¼" rigid or flexible magnesium anode(s) (25 gm/sq ft of vessel surface area) is/are supplied with all glass lined tanks.|
|Constituents:||Contains not less than 70% of refractory oxides such as silicon oxide, aluminum oxide, calcium oxide, magnesium oxide, titanium oxide or zirconium oxide. The proportion of silicon oxide is not less than 70% of the refractory oxides and is not less than 49% of the total quantity of the components in the glass lining formation.|
