  2. CORROSION RESISTANCE OF ZINC COATED STEEL IN

    polarization for uncoated and galvanized steel immersed in natural sea water From Fig. 3 it can be also seen that the corrosion current (i corr) of uncoated steel is higher than the corrosion current of galvanized steel which results in a decrease of the corrosion rate from 279.5

  3. Hot-Dip Galvanizing for Corrosion Protection Products

    hot-dip galvanized steel to combat corrosion. The value of hot-dip galvanized steel stems from the relative corrosion resistance of zinc, which under most service conditions is considerably better than iron and steel. In addition to forming a physical barrier against corrosion, zinc, applied as a hot-dip galvanized

  4. Performance of Hot-Dip Galvanized Steel Products

    Therefore, the performance of hot-dip galvanized steel varies from environment to environment. Environments in which galvanized steel is commonly used include indoor and outdoor atmospheres, the storage of hundreds of different chemicals, in fresh water, sea water, soils,

  5. Corrosion Resistant Coatings - Anti-Corrosion Coating ...

    Anti-corrosion coatings allow for added protection of metal surfaces and acts as a barrier to inhibit the contact between chemical compounds or corrosive materials. In addition to corrosion prevention, many of the coatings listed below also provide a bonus of abrasion resistance, non-stick performance and chemical protection.

  6. Aluminum vs. Steel for Salt Water Piping - Finishing

    Apr 21, 2012 · Aluminum vs. Steel for Salt Water Piping 2005. Q. I was given a project to design the piping to carry seawater from the ocean to an RO unit then to a storage tank. We have a length of aluminum pipe and steel of two different diameters. I cannot find a clear answer on which would be more resistant to salt water corrosion.

  14. Drinking Water Problems: Corrosion - Texas A&M

    Corrosion is a natural process that occurs when metals are in contact with oxygen and react to form metal oxides. All water is corrosive to some degree as it contains some amount of dissolved oxygen. The rate of corrosion depends on a number of factors including acidity or low pH, electrical conductivity, oxygen concentration and water temperature.
