When buying a water storage tank, working out the configuration and selection process often is something that needs to be done in the early stages of project design. Applying for and securing funding, timing of construction, and overall project costs all play a factor. As many areas have a single source of water storage, the tank design plays a crucial role in meeting the current and future needs of a community.
There are three types of liquid storage tanks available that are considered for municipal water storage applications: glass-coated bolted steel, welded painted steel and concrete.
Reservoirs have a greater diameter than height and can be used with a pumping system or can be gravity fed. Depending on the diameter, snow loads and other factors, the roof of glass-bolted tanks can vary. They can be a free-span aluminium geodesic dome, consisting of panels mounted on a rigid structural frame, or the same glass-fused-to-steel material.
The tank floors usually are constructed with reinforced concrete or they can be glass-coated panels depending on site and design conditions.
The technology and manufacturing process of this equipment sets these tanks apart from painted steel or concrete structures. When using the factory manufacturing process, the uncontrolled variables are eliminated – unlike field manufactured products such as painted steel or concrete tanks. Worker experience and extreme climatic environmental conditions that are proven to have a significant effect on in-field manufactured products have minimal effect on the glassing process. In addition, the tanks can be erected year-round as the manufacturing is completed in the factory and only the assembly of the components is required in the field.
All storage tanks have a coating. The coatings available today consist of either paint, concrete or glass. The water resistance and air tightness of glass offer advantages.
The glass coating process begins with a glass frit that is mixed with other minerals and water to create a liquid slurry. This glass slurry is then robotically sprayed in precise amounts and thicknesses on to previously cut and rolled, punched, grit-blasted and cleaned steel sheet panels. The panels through a furnace at around 815DegreeC. This heat melts the silica glass slip into the surface of the grit-blasted steel. This completes the mechanical bond, as well as the chemical bond between the steel and the silica glass.
Different coatings for other tanks rely on a mechanical bond of the coating to the underlying material. The chemical bond strength is many times the holding strength of the conventional mechanical bond and prevents any undercutting of the coating, which can allow spreading of corrosion on the primary steel material. This benefit can best be explained by imagining a scratch on an automobile. Because that coating only has a mechanical bond, if the steel is exposed, corrosion will occur. Left untreated this corrosion will expand and creep beneath the surrounding painted surface and compromise the remaining coating.
This often is witnessed with raised bubbles, spreading rust and weakened substrate. The chemical bond of the glass-fused-to-steel coating prevents this spreading of corrosion in the event of the coating being compromised.
A jacking system is used when erecting a glass-coated bolted steel storage tank. Tanks are assembled from the top down allowing for a safer and faster construction environment. The erection process is normally completed within a week or two, which saves costs to the owner if you’re paying for staff to be on site.
Glass-coated, bolted steel tanks have a long lifetime. Glass-coating never needs painting because its appearance is permanent, meaning they are a great option in areas where a pleasing visual appearance is sought. Repainting budget or repair budget for aged concrete can be saved and prioritised elsewhere.
The bolted design and erection of this product gives flexibility. Because manufacturing is completed in a factory, there’s no need for a large staging area. The construction of the tank typically can be completed with a cleared area of roughly 2m-3m around the tank diameter. This small footprint can save thousands on the overall project beyond the price of the tank itself. The panels themselves can be hand-carried and easily assembled without cranes or special equipment, allowing this tank to be installed in many locations that would be impossible for other tank types.
Initial construction costs, anticipated life and long-term maintenance costs are significant factors relative to the various tank designs and materials available today. The long-term maintenance costs and life cycle must be considered when selecting the appropriate tank product for a specific project.
Glass-Fused-to-Steel Tanks is made of glass fused to steel plate, special sealing material, self-locking screw and other materials. The thickness of enamel steel plate can reach to 20 mm, the most used steel plate thickness is 3~10 mm, steel plate has surface oil, contain rust, contain oxide skin, after shot blasting, sand and other pretreatment process, the steel plate surface will be clean. After 900 ℃ high temperature second enamelingl in electric furnace, 0.3 mm enamel coating is applied on both sides of steel plate. strong binding force between enamel coating and steel plate. Enamel coating can not only prevent tank corrosion, but also has the function of strong acid and alkali resistance. And has extremely strong wear resistance.
GFS is lined with glass enamel both inside and outside. The enamel is a strong, smooth and shiny silicate coating. It is melted in a special furnace with a temperature range of 780 to 900 degrees Celsius. The steel circular (cylindrical) shell of the tank is made of two layers of glass fused sheets, coated on both sides. These plates are fixed with special high-grade bolts and sealed by a continuous flexible silicone (sealant).
Glass-Fused-to-Steel Tanks are popular because of their durability and long service life. Fused coatings are suitable for any application, but they are particularly effective in retaining corrosive liquids (such as wastewater and landfill leachate) because the coatings can withstand chemical attack that can damage and degrade other types of Storage Tanks. GFS storage tanks never need to be repainted, no matter what is stored in it, they can be cleaned with an electric washing machine and almost no maintenance is required.
The connecting materials and housing accessories are all surface-treated. Glass fused to steel tanks can be used to store fluids or lost materials. The characteristic of these storage tanks is that they have been approved for use as industrial storage tanks. GFS/gls tanks are also the basic building elements of environmental technology facilities, such as wastewater treatment, fire-fighting water storage and anaerobic digestion tanks.
