The function of anticorrosive coating for pipeline products

The anti-corrosion principle of the anticorrosive coating is to prevent H2O,C1-,SO2 and other corrosive media in the environment from penetrating into the metal surface,so as to isolate the corrosive medium from the metal surface and prevent the corrosion of the metal.The main functions of pipeline anti-corrosion coating are as follows:(1)shielding effect.(2)corrosion inhibition performance.(3)sacrificial anode protection.(4)performance improvement.

Flange coating with interthane 990 Polyurethane

In order to improve the anti-corrosion performance of the coating and achieve the anti-corrosion effect of the coating,combined with the actual situation of pipeline anti-corrosion,the requirements for the anti-corrosion performance of the coating are as follows:(1) good stability to the corrosive medium. (2) good impermeability to ensure low water absorption. (3) good mechanical strength. (4) excellent electrical insulation.
