Galvanized tanks are among the most widely used water tanks for smaller volumes. Galvanized water tanks can be manufactured on-site or in the factory. Cold and hot-dip galvanized sheets are joined using welding processes. A high degree of corrosion can occur extensively at the welds if the wrong electrode is chosen, leading to rusting and corrosion. Recently, with the entry of several companies into the field of importing or producing prefabricated or modular galvanized tanks, these tanks have the potential to capture a significant market share. Since modular galvanized tanks have no welds, they ultimately will not experience any corrosion. Considering the seismic activity of the country, prefabricated galvanized tanks offer high resistance to earthquakes.
Prefabricated galvanized tanks offer very quick installation and can solve problems associated with tanks made from other materials. Another new type of tank recently introduced in the water industry is the glass-lined tank. These tanks have an iron core and a glass enamel coating. Glass-lined tanks can be manufactured and installed up to volumes of 5000 cubic meters. They have very high resistance to corrosion and have a very short installation time. Glass-lined tanks are among the best in terms of drinking water quality over time, corrosion resistance, and earthquake resistance. The glass lining can be applied to limited volumes and surfaces. This lining can also be used for manufacturing acid tanks. Generally, GRP tanks are tanks that, due to environmental concerns, will only be used in specific fields. The primary application of GRP tanks is in the oil, gas, and petrochemical industries.
