How To Protect Against Corrosion

The corrosion process takes place when there is water in the air at a high relative humidity. The limit of humidity lies under the value of 45 - 50 percent RH and what this means is that if you want to protect against corrosion and store glittering steel without any risks the humidity must be bellow that limit. But if the atmospheric humidity is above 60 percent then you will not be able to protect against corrosion and the process will set in. If the humidity process is between 60 and 100 percent RH the corrosion process will be importantly accelerated and in case of free water on the surface the corrosion process will start very quickly and there is nothing you can do to protect against corrosion.

Thus in order to protect against corrosion you will need to keep a constant, low atmospheric humidity and the materials you are trying to protect must be stored in a hall or a dry air storage room. In order to protect against corrosion you can try a dehumidification process if the corrosion does not depend on the temperature of the room. Consequently, further surface treatment of the material is not necessary.

Also major machineries with large internal surfaces may be protected from internal corrosion when not in operation. The application examples that this can be applied to include military aircrafts and tanks, bridge constructions, windmill towers, containers and vessels, heating stations, power stations, dry air storage, sugar refineries, boilers, garages and hangars, condensers and turbines. The methods you can use to protect against corrosion all these equipments, but not only them are hot dip galvanizing, epoxy coating, pre-grouted bars, extruded polyethylene coating, corrosion inhibited compound. etc.
