With the expanding use ofthe reverse osmosis desalination plants, the problems associated with weld metal decay and HAZ concentrated corrosion is being reported. The required long term 24–hour service ability and the high level dependability ofthe apparatus coupled. with excessive rates of corrosion detected, necessitates establishing the mechanisms involved. Effective parameters include high concentrations ofaggressive anions in different media comparable to the oil slurry and brine as well as susceptible phases generated during pre\post heat treatments. Following accurate chemical analysis of the raw, permeate and reject waters as well as the evaluation ofthe pipeline andweld metal materials before and after service; extensive microstructure and phase measurement studies were conducted. The results showed.that the copious ferrite furmation as a result ofchanges in equivalent carbon content could be the main cause ofthe detected corrosion. SEM and low angle XRD studies revealed the interconnected nature of scattered secondary phases. Sulfur was spotted in both different aqueous media and surface deposits, indicating the possibility of hydrogen ingress and possible HE damage.<\div>

Connate water or produced water is any water that exists in reservoir with hydrocarbon sources and is extracted by crude oil or natural gas when hydrocarbons are extracted indeed they are brought to the surface in a combination form of an extracted fluid combination of this fluid depends on this that either oil is extracted or natural gas and generally it includes a mixture of liquid hydrocarbons and gassy hydrocarbons connate water dissolved or suspended particles extracted solids like sands clay mud injected fluids and additives that may be in the composition resulted from exploration and production activities.<\div>
