Corrosion Inhibitor Para B9331

Corrosion inhibitor “V 9381” is a water-alcohol mixture of organic compounds based on organic phosphonates. The reagent also includes organic dispersants and azole compounds.

The inhibitor is intended for corrosion protection of heat exchange equipment and communications in water circulation systems through cooling towers, as well as in water vapor-condensate systems.

Corrosion inhibitor “V 9381” is produced in three grades A, B, C in accordance with the current technical conditions TU 2458-063-17423242-2012.

Protection of equipment for water circulation systems

Application

The inhibitor “B 9381” is dosed into the water circulation system constantly using a dosing pump. Dosing can be carried out directly from product drums or from working plastic containers. For ease of dosing, the reagent can be pre-diluted with water. The supply of the reagent to the make-up water is considered more efficient. 

Dosage

The dosage of the inhibitor “B 9381” depends mainly on the hardness of the water. As a general recommendation, the working concentration of the inhibitor in the circulating water should be 20-50g / m3. At the initial use of the inhibitor, shock dosages of about 50-100 ppm in the volume of circulating water are recommended for 1-3 days to form a protective film.
