Abstract

The growth of sulfate reducing bacteria (SRB) under different magnetic field strength was studied by using microbial method. The corrosion rate of X100 steel in simulated solution of SRB steel under different magnetic field strength was calculated by the method of weight loss. It was found that the magnetic field could inhibit the growth of SRB, and the stronger the magnetic field intensity was, the stronger the inhibition effect was; The magnetic field could inhibit the corrosion rate of X100 steel, and the corrosion rate of X100 steel first decreased and then increased with the increase of magnetic field strength. When the magnetic field strength was 5 mT, the corrosion rate was the smallest. The influence of static magnetic field on the survival rate of microbe and the corrosion rate of metals were briefly introduced. A new idea for the inhibition of microbial corrosion in pipeline was proposed.
