... by the corrosive, high velocity gas flow. The corrosion rate of either the inhibited or uninhibited gas stream was too high for equipment in high pressure gas service. Type 410 (12% Cr) stainless steel was recommended for the choke bodies because other equipment such as valves made of type 410 showed no evidence...

... and the reduction of oxygen. Since the rates of oxidation and reduction must be equal, increasing the total reduction rate increases the rate of zinc solution. Therefore, acid solutions containing dissolved oxygen normally will be more corrosive than air-free acids. Oxygen reduction simply provides another means...

... corrosion was not dominant. When slurries are recycled in a closed slurry pot system, the wear rate can decrease dramatically with time ( Ref 13 , 14 , 15 ). This is due to the microscopic rounding of the abrasive particles. The difference in wear rates for recycled and flow-through slurries is shown...
