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".

What is Caustic Embrittlement ?Causes Prevention ...

Nov 14 2019 · In boiler sodium bicarbonate is used for softening of water and thus a small amount of it is present in the boiler water which on hydrolysis forms sodium hydroxide. This Sodium hydroxide makes the water saline and gets into the minute cracks. With time the water is evaporated and online salt remains in the cracks.

What is a Chelating Agent? - Definition from Corrosionpedia

Sep 17 2014 · Chelating agents are used in boilers to dissolve common types of scale during normal operation and provide effective online and offline scale removal in boilers. The surface active chelating agents are used as corrosion inhibitors to form insoluble surface chelates (compounds comprising of the chelating agent and the metal ion). Even though chelating
