Microbiologically induced corrosion is not in itself a form of corrosion, but rather a process that can influence and even initiate corrosion. It can accelerate most forms of corrosion, including uniform corrosion, pitting corrosion, crevice corrosion, galvanic corrosion, intergranular corrosion, dealloying, and stress corrosion cracking. MIC deteriorates pipes, tanks or vessel surfaces by pitting corrosion. Microbiologically induced corrosion can degrade or cause to fail many different types of system. The ultimate effect is the premature failure of metal components. To understand the causes and effects, it is necessary to understand the chemical, metallurgical and microbiological aspects of microbial corrosion were WJMG can preform all the test necessary.
