Tank Rejuvenation
Life Extension of Aging Tanks
Above-ground storage tanks deteriorate over a long time service. Corrosions, which are the most typical defects, on the steel cause serious incidents. Repairing of the tank at an appropriate time and in a proper way can extend the service life. Tank rejuvenation contributes to the safe operation as well as your facilities life.
