      • Abstract
    • The corrosion rate of seabed pipeline in sea mud was studied by weight-loss experiments and electrochemical measurements with A3 steel in simulated sea mud.The results showed that the corrosion rate of A3 steel in sandy soil was significantly higher than that in sea sand.The corrosion rate of A3 steel in sea sand increased with the increase of temperature.With the increase of SRB and SO2-4,the corrosion rate of A3 steel increased in sandy soil.The increase of corrosion rate of A3 steel in marine mud without SRB with the increase of temperature was mainly due to the increase of diffusion rate of oxygen as a depolarizing agent of cathode.SO2-4 could participate in the cathodic depolarization and accelerate the corrosion rate of A3 steel in sea mud with SRB.
