Understanding The Differences Between Derouging And Passivation
by Neil Brook on July 30, 2024
Stainless steel is the material of choice for a lot of industrial equipment, due to its durability and strong resistance to corrosion. However, to maintain these properties and sustain surface quality, many stainless steel applications require regular derouging or passivation.

Rouging and Derouging: Stainless Steel Chemical Cleaning
by Neil Brook on May 21, 2024
Rouge is made up of a variety of iron oxides (rust). It is important that corrosion products (rust or rouge) are not present in your manufacturing and distribution systems, tanks or equipment.
Rouge: What is it?
by Neil Brook on May 7, 2024
Rouge is a common problem in pharmaceutical facilities, most often found in high-purity water and clean-steam systems fabricated in austenitic stainless steel.
Passivation Of Stainless Steel
by Neil Brook on April 8, 2024
Introduction There are many industries that demand high-purity systems in which they can manufacture their products (pharma, food, cosmetics, semi-conductor, etc.) or whose processes are carried out in hostile environments and need to be assured that their equipment is up to the task …

Prevention of Contamination - Supplier Selection
by Neil Brook on June 16, 2020
Ordinarily, the main reason for having a chemical cleaning contractor on your site is to either remove a form of contamination from your equipment, or as part of a pre-commissioning activity to ensure your equipment is in optimal condition for service. It is therefore, of the utmost i …
Three Ways to Test the Surface Cleanliness of your Stainless Steel
by Neil Brook on April 29, 2020
Stainless steel gets its corrosion-resistant qualities from the chrome-oxide (passive) layer that forms spontaneously when it comes into contact with atmospheric oxygen. This protective layer is extremely thin and in order to fully form, the stainless surface must be thoroughly cleane …
