Pickling - Import export

Pickling is chemical etching of metal surfaces using an aggressive, alkaline solution to remove applied metal layers or to get an oxide-free surface (activation of the base metal for further coating). Maximum measurements 4000 x 1000 x 500 mm

Pickled and oiled Steel is meticulously cleaned using sulfuric or hydrochloric acid baths, followed by a protective oil coating to prevent oxidation. This type of steel is ideal for applications requiring strength and rigidity, such as machinery manufacturing, automotive side industries, and construction. Its high strength and formability make it suitable for producing LPG cylinders, pipe profiles, and structural components.

Acid recovery out of pickling acids Salts and acids can be concentrated or separated from solutions by electrodialysis. For this, ions (anions and cations) are transported through the ion exchange membranes by the applied electrical field. Typical examples for the usage of electrodialysis are: Acid recovery at pickling lines Recovery of metals out of electro-plating rinsing water
