  Acid storage tanks play a vital safety and operational role in both thermal and renewable power plants by securely containing highly corrosive acids and chemicals used in various plant processes. These tanks are engineered from corrosion-resistant materials such as polypropylene, HDPE, fiberglass reinforced plastic (FRP), or stainless steel to withstand harsh chemical environments, prevent leaks, and reduce risks to personnel and equipment. Properly designed tanks incorporate features like venting systems to release hazardous vapors, robust secondary containment to avoid environmental contamination, and temperature controls to maintain stability of stored chemicals. In thermal power plants, acids may be used for boiler cleaning, water treatment, or other maintenance tasks, making safe storage essential to prevent corrosion or accidental release. In renewable energy facilities like concentrated solar power plants, similar storage systems ensure acids used in heat transfer fluid...

  The blog explains the key differences between Hot Dip Galvanizing (HDG) and Electro-Galvanizing (EG), two popular zinc-coating methods used to protect steel from corrosion. Hot Dip Galvanizing involves immersing steel into molten zinc at around 450°C, forming a thick zinc–iron alloy layer. This results in a strong metallurgical bond and a heavy coating thickness of 45–120 microns. Because of this, HDG offers long-lasting corrosion resistance, often protecting steel for 20–50 years even in harsh outdoor environments. However, its finish is rough and matte, making it less ideal for applications where appearance and precise dimensions are important. Electro-Galvanizing, on the other hand, uses an electrolytic process at room temperature to deposit a thin zinc coating, usually 5–25 microns. EG provides a smooth, bright, and uniform surface finish, making it suitable for automotive parts, home appliances, indoor components, and products where aesthetic appeal and tight tolerances m...
