Corrosion prevention is one of the aspects done by corrosion engineers. Corrosion can be minimized by altering the physical attributes of the material being used or changing the material with new metal or by finding means to combat corrosion. The goal of this study is to evaluate the suitability of grade B low carbon steel to low pH (2.5-4.0) fluids at a temperature range of 70-100 centigrade. This was accomplished by measuring the corrosion rate of grade B low carbon steel to geothermal brine samples at pH range of 2.5-4.0, temperature range of 70-100 centigrade and velocity range of 475-710 rpm through immersion tests. Result shows that the different controlled parameters such as temperature and pH significantly affect the corrosion rate of grade B low carbon steel. The fluid velocities covered by this study, however, has no significant effect to the corrosion rate of grade B low carbon steel.
