corrosion inhibitors in water treatment - Degremont®

In high temperature or sealed systems such as boiler circuits or domestic central heating systems, effectiveness drops to very low values as the result of the reduction of the oxygen dissolved in the water. Chemical products used for this purpose tend to be reducing agents designated "oxygen absorbers".

Passivating carbon steel / when to

Mar 27, 2009 · To begin with, carbon steel boilers don't rust because the pH of the water is kept above the oxidizing point of steel which is about 8.2 - 8.3. The magnetite coating is a chemically induced conversion coating (also called black oxide), that if left in a pH environment below 8.2 will start to rust.

QUIZ: Boiler Water Treatment Chemical Guidelines — Part II

Chelating agents offer an opportunity for supplying better results in boiler water treatment (i.e., cleaner boilers). The important key to success is to use the same care in selecting, applying, and controlling the treatment program. Chelating programs are another variation of water treatment. The word chelate derives from the Greek word chele,

Industrial Rust Removal Acids and Water-Based Solutions

Mar 10, 2020 · It is not only acids that have the ability to remove rust. Acid-free, water-based rust industrial rust removers utilize a slightly different chemical process to react specifically with rust and remove it from the metal. While acids break down and dissolve rust, acid-free, water-based rust removers draw the rust away or lift it from the metal.

What is Caustic Corrosion? - Definition from Corrosionpedia

Oct 08, 2016 · When boilers operate, the temperature rises and causes fabrication stress around rivet holes, eventually causing cracks in the steel boiler shells and tube plates near the weak portions of the metal. The alkaline water enters the minute holes and cracks by capillary action in the interior of the boiler.
