3. WATER TREATMENT

Before and during assembly, the system must be kept free
of impurities, construction dust, sand, copper dust, grease,
carbon deposits, etc., as well as welding flux residue. In
any of these instances, the old system must be rinsed with
clear water mixed with a highly concentrated rinse agent.
More generally, it is advised to implement any procedure
necessary to prevent or treat contamination.
Black oxide sludge (magnetite-Fe
continuous electrolytic corrosion in any system unprotected
by an inhibitor. Iron oxide (Fe
produced during oxygenation. Scale deposit is made
up of lime scale contained in most distributed water that
settles over the warmest surfaces of the system. Sludge
and scale do mix together and are the cause of the main
encountered field problems on heating installations.
The presence of these substances means that standard
precautions are not implemented. In this case, product
warranty cannot be applied.
The chemical compatibilitiy of several products for the
treatment of heating water equipment has been tested on
heat exchangers.
Raypak recommends the using of these corrosion inhibitors
in preventive and curative treatment for boilers.
