Pickling Tanks

Pickling tanks are specialized containers used in the pickling process, a metal surface treatment method. In this process, metals (like steel, stainless steel, or aluminum) are submerged in a chemical solution, typically acids like hydrochloric acid, sulfuric acid, or nitric acid, to remove impurities such as rust, scale, or oxide layers. This treatment helps clean and prepare the metal surfaces for further processing, such as coating, plating, or welding.

Pickling tanks are often made from materials resistant to the corrosive nature of acids, such as high-density polyethylene (HDPE), polypropylene (PP), or fiberglass-reinforced plastic (FRP), depending on the application and the chemicals used. These tanks need to withstand the harsh environment and chemical reactions involved in  the pickling process.

Small tanks have a capacity of a few hundred liters while the big tanks have a capacity of over 20,000 liters. These tanks are built to the size of metal objects which will be treated in the tank.

SHEPL is immensely proud to be the company in the world to weld the main body and the end walls of the tank using the “Butt Fusion” technique which gives long life to weld seams which eliminates the risk of tank failure or leakage.

• Sheets are welded using German Wegner Welding Machine according to DVS norms which eliminates leakage and ensures a long lifespan.
• 100% leak proof welding.
