- Some defective results and accelerating corrosion phenomena due to the improper use of cathodic protection devices were discussed, and some methods for preventing corrosion were presented.
- It prevents water entrapment; water entrapped in the valve internals will accelerate corrosion.
- The removal of protective film bylow intensitycavitations forces means that oil additives which attack base metal will accelerate corrosion.
- Usually,corrosion resistance of weathering steels is evaluated by the weight-loss method in an accelerated corrosion test.
- Research progress on accelerated corrosion test method which can evaluate the corrosion protecveness of the post tensioning grouts is reviewed.
- Excess ozone production wastes energy, can accelerate corrosion and result in excessive off gassing in the area of the distribution piping.
