Inhibitor Protection of Raw-Water Heaters against Corrosion and Scaling

We propose a new technological procedure aimed at the protection of pipes of raw-water heaters made of 20 steel against corrosion and scaling by using the KORSOL-1M inhibitor (based on phosphates). For the optimal concentration of the inhibitor C ^sub inh^ = 200 mg/liter, the time of continuous oper...

Summary:We propose a new technological procedure aimed at the protection of pipes of raw-water heaters made of 20 steel against corrosion and scaling by using the KORSOL-1M inhibitor (based on phosphates). For the optimal concentration of the inhibitor C ^sub inh^ = 200 mg/liter, the time of continuous operation of heat-exchange pipes of raw-water heaters increases up to 5-6 months. During the downtime, it is reasonable to apply "soft" chemical cleaning because the layer of scale on the steel surface become amorphous and thin ([asymptotically =] 1 mm) and can easily be removed from the surface. The time of chemical cleaning is halved. In raw water, the KORSOL-1M inhibitor does not impair the operation of the subsequent chain of mechanical and ion-exchange filters.
