The customer is facing a big challenge to overcome the corrosion problem on the internal surface of the valves after hydrotesting, also some corrosion is usually noticed on the flange surface during and after transportation because of the harsh environmental condition.
Cortec VpCI®-649BD and VpCI®-368 were tested and agreed to be applied during hydro testing and transport stages. VpCI®-649BD was added to hydro test water tank and the concentration was maintained to provide protection during and post hydro testing for up to one year. VpCI®-368 was applied on the flange surface only to provide protection from corrosion because of the environmental condition during transport.
Cortec provided the long term corrosion protection system needed to keep the customers’ businesses running smoothly and efficiently. The customer was pleased and satisfied with the results offered by using Cortec products.
