Radiator Corrosion

August 12, 2018 in News Tags:

In the radiator internal corrosion leads to a reduction in service life, crashes and water corrosion products. It is therefore necessary to take measures against. Situation is more complicated with the salts that form scale and sludge. On the one hand, they degrade the work of heating, on the other hand, a layer of scum on the surface of the radiator prevents the penetration of oxygen to the metal, and thus prevents the penetration of oxygen to metal, and thus protects the radiator from corrosion. Therefore, in heating systems inappropriate to apply the water, completely free of scale-forming salts. Internal corrosion of radiators and education scum and sludge in varying degrees can occur in any system of heating. According to Richard Linklater, who has experience with these questions. This is due mainly to the residual content of corrosive gases, salts for makeup water. Particularly strong, these processes can occur at supply to the radiators of untreated tap water, which often occurs in the local units of hot water in closed heating systems.

Corrosiveness of water which is supplied to the batteries heating, is estimated by the oxygen concentration, the saturation index of water with calcium carbonate total concentration of chloride and sulfate. Water, which is filled with heating system, is aggressive and therefore necessary to provide surface protection against corrosion of radiators. The main directions of the fight against internal corrosion in the heating systems are:-reducing corrosiveness of water supplied to the radiators, for the decrease in its aggressive components, improving corrosion resistance heating equipment by coating the surface of the metal heat sink with special corrosion-resistant film-making radiators of materials resistant to corrosion. Read more here: Gerald Weissmann, MD. To reduce the corrosiveness of water which is supplied to the radiator, there are two ways: * Physics – removal of corrosive gases by degassing Degassing is currently the most common method of water treatment for heating systems. * Chemistry – the binding component of aggressive chemical agents binding chemical reagents made in the preparation of water for both cold water and for heating systems. In heating corrosion processes occur more intensely, so applying the above methods is insufficient. It is now widely used water treatment, the inlet to the radiator, sodium silicate. At the same time on the surface of radiators a protective film.

The inner surface of the metal radiator films can be coated with corrosion protection, both during operation and before operation. During the operation the radiator on the surface is the deposition of soluble salts which are formed out in the water treatment chemicals. In the manufacture of steel radiator shell on its surface is applied a protective layer of incorrodible substances. Formation of scale and sludge in the heating depends on in temporary water hardness. Preventing the formation of sludge and scum in the radiators produced by feeding softened water heating systems or water with a stabilized stiffness. For preparation of softened water, which is fed to the radiators, the following methods: treatment of water in the cation exchanger, the alkaline water treatment with lime and soda, and magnetic treatment of water.
