Derouging: Treatment and Removal of Oxidative Phenomenon for Pharmaceutical Companies
BAMA specializes in a particular treatment called Derouging.
But what exactly is Derouging? Or rather, what is the phenomenon known as Rouge?
"Rouge" is an oxidative phenomenon that appears on the surfaces of stainless steel, especially in the pharmaceutical sector, where austenitic alloy products are used for transport, storage, and sterilization, such as pipelines, tanks, reactors, and autoclaves.
As its name suggests, "Rouge" causes a discoloration of the steel surface, ranging from light red to brown, depending on the severity and nature of the phenomenon. It is a specific complex of oxides that forms beneath the passive layer of stainless steel, which, besides being unsightly, can also lead to corrosive issues over time.
Although not widely known, Rouge is increasingly becoming a problem for pharmaceutical companies, which are subject to strict inspections by national and international bodies. The sight of Rouge-stained surfaces on a tank or autoclave used for sterilizing medical materials like blood or plasma bags, or for containing water for injections, often represents a critical concern for the pharmaceutical industry.
Thanks to its internal research and available equipment, BAMA can remove this phenomenon and restore the stainless steel surface to its original condition.
To achieve this, BAMA uses neutral products, avoiding acids or bases that could damage the stainless steel surface. These products are formulated in BAMA's laboratories and produced in BAMA's facilities.
Over time, BAMA has increasingly specialized in the removal of Rouge and boasts numerous successful interventions for major pharmaceutical companies. Our company has equipped itself with new, portable, small-sized plants that can be brought directly to the facilities needing treatment, such as pipe loops, sterilization autoclaves, storage tanks, steam production systems, and reactors.
The treatment lasts only a few hours and is always followed by a passivation process to restore the protective "good" oxide layer on the stainless steel surfaces, making them practically as good as new.
