Corrosion healthy in equipment of big industries such as oil industries as well as the quality of its transmission is an important and basic problem which disregarding of this phenomenon causes to stop production and consequently cost repairing. In this paper a kind of nano-composite coating is used to prevent atmospheric corrosion and under insulation corrosion. This coating that consist of 03 percent of acrylic resin water based and 03 percent of nano-composite as well as the nanometer tunnel (the thickness of tunnels is only a few nano meters) covers the surface completely, so that there is not any microscopic space for air penetration (percolation). In addition to the hydrophobic properties will remove the moisture from the insulation surface. Thus this nano-coating insulation prevents from reaching moisture oil and gas transfer pipeline, also this type of insulation is semi-transparent. In the other hands, its space beneath is visible each time. In order to test this nano-coating, GM0453P test this has been approved as environmental corrosion test was used. After the first stage of test, the surface without coverage was corroded entirely, but the coated part was tested successfully without any effect of corrosion after 45 stages. Although there are numerous ways and materials to create resistance against corrosion, but insulation and anti corrosion properties aren’t considered synchronous; the coverage used in this test includes both properties.
