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