First of its Kind – Double Wall Glass Fused to Steel Bolted Storage Tank for Leachate Containment Leachate Tank with Double Aluminum Cover, Eugene OR
These types of bolted tanks are commonly called “glass lined” (GLT, “glass fused-to-steel” (GFS) or “glass coated” (GCT) depending on the region where they are installed, but these names all mean the same thing, that the tank panels are fused inside and out with a glass enamel that binds to the metal providing many advantages over standard epoxy coated or welded painted storage tanks.
The glass lining forms a hard, chemically inert layer that permanently protects the steel surface from rust, corrosion, undercutting, abrasion and stains. In addition, UIG’s proprietary ECOGlass coatings are specifically engineered around your application from pH zero to pH 14 providing even more corrosion resistance.
The Glass Fused-to-Steel construction of these bolted tanks is exceptional for the storage of potable water, waste water, petroleum, chemicals and dry bulk an in such applications as reservoirs (open top or with aluminum dome or fat panel roof), power generation stations, standpipes, frac processing, fish ponds, sludge tanks, trickling filters, high temp fermentation plants.
They are used in many different applications such as waste water treatment plants, biogas plants and petroleum tank farms where steel corrosion would be an issue. Glass Lined Tanks are quick to manufacture and can be erected easily in the field with our experience crew or by utilizing a supervisor and local labor.
Pair with our UIG Aluminum Dome Cover for virtually maintenance free storage.
WHY CHOOSE A GLASS FUSED-TO-STEEL TANK?
Glass Fused-to-Steel Bolted Tanks are a very popular choice for water storage tanks but how do you make sure you are specifying the right manufacturer for your project?
UIG Glass Lined Storage Tanks no only conform to the AWWA D103 standards but FAR EXCEEDS the standards by providing a stronger, safer product.
Don’t be fooled into thinking that a set of specifications written by a particular manufacturer is the AWWA D103 standard. Many times the writer of those specifications put in extraneous requirements to weed out the competition and give the buyer fewer, if any, other choices. This tactic is not to the benefit of the project owner. Your UIG Glass Lined Tank Specialist can explain to you the differences between the current AWWA D103 standard and a specification written by a manufacturer.

ECOGLASS BOLTED TANK COATING
UIG utilized thinner coatings than other manufacturers which increases the role of the base metal’s mechanical properties, providing a harder, more flexible, less brittle and greater chip resistant tank panel. UIG’s proprietary enamel fits and titanium rich steel (TRS) provides unparalled adhesion. Proper coating thickness is key to elasticity and longevity. The tensile strength is approximately the yield point of the base metal. In general, thinner porcelain enamel coatings are more flexible and have greater resistance to fracture. Normally, heavier coatings are used on cast iron or appliances where rigidity of the substrate resists deformation and reduces the danger of fracture. Thickness over 16-mils is not generally recommended for sheet/plate metal parts because or warping and/or chipping problems.

UIG uses proprietary Titanium (Ti) rich Hot Rolled Carbon Steel (TRS) which is specifically manufactured for the enameling process. This allows for exceptional physical performance and eliminates any fish scale defect. Furthermore the superfine glass structure of the enameled layer provides the steel plates with excellent flexibility and durability. Other manufacturers choose a poorer quality A36 Carbon Steel base (not recommended for durable and quality glass fused bonding), which is the least expensive steel and contains levels of carbon that will make it difficult for good glass adhesion. Many manufacturers apply a toxic nickel oxide to cover up the carbon defect in inferior steel in order to apply their two-coat/two-fire enameling process which will leach through any pinholes. As a result they end up with thicker coating that has the tendency to fish scale, sag, has low adherence and cracks easily.

BOLTED TANK PANEL EDGES
Sheet edges must be properly coated with the same enamel material in order to avoid electrolysis of dissimilar metals, rust and weakening of the enamel bonding. UIG rounds the edges of their plates and coats the edges completely. To save time and costs, other manufacturers leave sharp edges on their panels and they coat them cosmetically with a stainless steel strip. This creates three dissimilar metals to cover their defects which will lead to nickel oxide leaching and early corrosion inside the tanks.

Most manufacturers use the same fin-necked bolts to assemble their glass lined tanks as they use for their epoxy coated tanks. Epoxy tanks may be touched up in the field which allows for the use of these types of bolts, but using these same bolts on glass lined tanks allow the fins to bit into the enameling leading to cracking and scratches which can cause rusting inside the tank.
UIG’s proprietary finless bolts are safe to use with glass fused-to-steel bolted tanks and do not crack the enamel during the installation process.
