Pickling is a metal surface treatment process used to remove impurities such as stains, inorganic contaminants, rust, and scale from ferrous metals, mild steel, stainless steel, copper, and aluminum alloys. The process uses a chemical solution known as pickle liquor, typically containing acids, to clean and descale metal surfaces. It is widely applied in various steel manufacturing and surface treatment operations.

Myrangoli™ offers both inline pickling systems and batch pickling tanks for the steel industry. These tanks can be supplied along with complete accessories such as water or acid curtain systems, circulation pumps, piping, side sight glass, heating and cooling elements, hood, scrubber, centrifugal exhaust fan (blower), ducting network, stack (chimney), and level indicator assembly.

The tanks are manufactured using Dual Laminate thermoplastic liners such as PP/FRP (Polypropylene + Fiberglass Reinforced Composite Plastic), PPH/FRP (Heat-Stabilized Polypropylene + FRP), as well as FRP and GRP (Glass Fiber Reinforced Composite Plastic), depending on process and chemical requirements.

Dual Laminate PP/FRP Pickling Tanks vs Only Thermoplastic (PP, HDPE) Pickling Tanks

Thermoplastics have been widely used for their excellent chemical resistance for over 50 years. However, their relatively lower mechanical strength makes the design of large tanks challenging. Dual laminate construction combines the chemical resistance of thermoplastics with the mechanical strength and flexibility of FRP. In this system, the thermoplastic liner is thermoformed and welded, after which FRP is chemically or mechanically bonded to the liner. Although this construction involves a higher initial cost, it is often justified by longer service life, reduced maintenance requirements, and improved process productivity.
