does corrosion increase with high ph or low and why? what is its effect in tubes

Answer 1

Answer #1

Answer;

The corrosion rate depends on pH, with lower pH causing an increase in corrosion rate.This pH dependence is ambiguous to the observation probability of fracture under a layer of deposits in carbonic acid media at pH greater than 7 is high.
As the intergranular corrosion of the fireside surface of the tubes increases the mechanical properties of the tube metal deteriorates. Under these circumstances if the temperature and pressure of the tube elevate abnormally due to some reason, the tube will burst.
