In a case that coating like heat shrinkable sheet (HSS) or cold tape is detached from buried pipeline surface, cathodic protection current can't penetrate into the pipeline surface enough to polarize cathodically due to the impervious characteristic of outer backing layer. Microbiologically induced corrosion can develop seriously at the pipeline inside the failed coating under the favorable environment for sulfate reducing bacteria (SRB) proliferation. A series of works have been performed in order to develop the antibacterial coating against SRB. Minimum inhibitory concentration (MIC) and thermal treatment effect on the antibacterial activity simulating the temperature of production and application were evaluated for the optimal biocide selection. Coating properties as well as antibacterial efficacy of HSS adhesives incorporated with reagent graded agents and industrial biocides were tested. Prototypes of antibacterial HSS system fabricated at factory have shown that the antibacterial coating could be developed to the level of commercial product.
