DEASCO can offer preservation applications using Nitrogen or Vapour Phase Corrosion Inhibitors. Prior to preservation, internals of the pipelines will be cleaned or flushed. With the selection of Vapour Phase Corrosion Inhibitor, it is mandatory to take into account the manner of flushing before commissioning takes place and or taking the package into production. Nitrogen can be used as preservative medium for Hydrocarbon Systems.
