Rouge formation can cause corrosion problems<\/h2>\n

Stainless steel is widely used in pharmaceutical applications. The cleaning of this stainless steel is very important because hygiene is a very high priority in the pharmaceutical industry.<\/p>\n

One of the phenomena that occur with stainless steel, almost exclusively within the pharmaceutical industry, is rouging. Rouging is a red-brown film of iron oxides and iron hydroxides and is found in systems that come into contact with ultra pure water.<\/p>\n<\/div>\n<\/div><\/div><\/div><\/div>

\n
\n\t

Conventional pickling can not be used<\/h3>\n

Conventional pickling will dissolve the passive layer and thus remove rouge, creating a clean surface. A disadvantage of this is that this process etches the surface, making it rougher and giving the finish a matte finish.<\/p>\n<\/div>\n<\/div><\/div><\/div>

\n
\n\t

Why not?<\/h3>\n

Ra-critical components are destroyed in this way or need at least a further polishing treatment to obtain the correct surface roughness. Pickled surfaces will become rougher and therefore more susceptible to further rouging and fouling of other (process) contaminations.<\/p>\n<\/div>\n<\/div><\/div><\/div><\/div>

Vecom has the right solution<\/h2>\n

Vecom has developed a cleaning procedure that removes the affected passive layer and removes the rouging without adverse effects (roughening of the surface and matte finish).<\/p>\n

After this cleaning procedure (or any other), the system must be completely chemically passivated.<\/p>\n<\/div>\n<\/div><\/div><\/div><\/div>

Especially in the pharmaceutical industry, hygiene has a very high priority<\/b><\/span><\/p>\n<\/div>\n<\/div><\/div><\/div><\/div>
