10″ Cooling Water Line MIC Repair with Thermo-Wrap Inspectable

Micro-biologically Influenced Corrosion (MIC) attacked over 2,000 weld locations on thousands of feet of a refinery’s stainless steel cooling water lines. MIC, bacterial induced corrosion, is caused by approximately a dozen known species of bacterial microorganisms. These bacteria thrive in water or soil conditions with a pH of 4 to 9 or temperatures of 50F to 122F (10C to 50C). If left unchecked in piping, they will make their presence known by causing pitting, especially at vulnerable welds. Read the case study below to learn more about how NRI’s composites were able to stop MIC.
