All our bolted steel potable water tanks are ready for sale. When constructing bolted steel potable water tanks, the selection of the best material is an important quality factor. Bolted Glass Fused to Steel potable water tank is the only tank finish where two materials are fused together to achieve the best of both: the strength and flexibility of the steel combined with corrosion resistance of the glass, which are ideal if you need to store municipal/industrial waste water and sludge or certain processing, intermediate and end products from the chemical, pharmaceutical and food processing industries. Bolted tanks are made from individual sections that are manufactured and finished offsite, greatly reducing the time and labor involved in the field. Once delivered, each section is erected, sealed with gaskets and bolted to adjacent sections. This results in an installation process that is quick and easy, far faster than installation of concrete or welded tanks.The installation time for bolted tanks depends on the sizes of the tanks installed, and the complexity of the installation process. Normally, the installation is very quick, often requiring less than a third of the time it typically takes to complete a welded or a concrete tank. Center Enamel is the leader in bolted steel potable water tank in China, Glass Fused to Steel tanks and Bolted steel tanks.

To feed the growing world population, increasing agriculture production is required. under such circumstance, premium containment solution is required for crops & forage storage, manure, sludge, irrigation during agriculture production. Agriculture waste such as livestock and poultry manure and energy crops are an important part of the global growth of green renewable energy solutions. Center Enamel Glass-Fused-to-Steel Tanks are made of special steel plate, special sealant, self-locking bolt, and the service life for more than 30 years. After pretreatment, the special steel plate is coated with two or three layers of enamel coating on both sides. After the heat polymerization, a strong binding force is formed between the coating and the steel plate. The protective layer formed by the coating can not only prevent corrosion of the tank body, but also has the function of strong acid and alkali resistance and strong abrasion resistance. Center Enamel Glass-Fused-To-Steel Water Tanks for irrigation in agriculture. In order to ensure the normal growth of crops and obtain high and stable yield, it is necessary to supply crops with sufficient water. Under natural conditions, crop water requirements are often not met due to insufficient precipitation or uneven distribution. Therefore, artificial irrigation is necessary to make up for the lack of natural rainfall. Also, we can use Glass-Fused-To-Steel Tanks to Collect and store rainwater that falls onto buildings and using it for agricultural purposes, which can cut the bill of irrigation water. That is why we choose Glass-Fused-To-Steel Tanks as for irrigation in agriculture, also can be widely used in vegetables, flowers, orchards, medicinal plants planting places.

Glass-Fused-to-Steel Tanks are made of special steel plate, special sealant, self-locking bolt, and the service life are more than 30 years. After pretreatment, the special steel plate is coated with two or three layers of enamel coating on both sides. After the heat polymerization, a strong binding force is formed between the coating and the steel plate. The protective layer formed by the coating can not only prevent corrosion of the tank body, but also has the function of strong acid and alkali resistance and strong abrasion resistance. We use the titanium alloy special steel plate as an enamel steel plate, which is twice as strong as ordinary steel plate, the commonly used steel plate thickness from 3mm to 12mm. The inner and outer sides of the steel plate are sprayed with ground glaze and surface glaze. after heat treatment at 850-940â??, the steel plate surface will form a 0.3mm thick enamel coating, which will not only prevent the corrosion of the steel plate, but also has the function of a strong acid, strong alkali resistance. And the self-locking bolt installation is very easy to install, no need for big installation equipment and/or very skilled labors.
