Glass Reinforced Epoxy (GRE) liners
Providing cost-effective corrosion protection for your injection wells.
Injection wells are known to face complex environments, such as untreated fluids, high salinity, corrosive gases (CO2, H2S, O2) and microbiology activity. Carbon steel tubings with Glass Reinforced Epoxy liners are field proven in such corrosive environments replacing costly CRA grades.
Vallourec has developed this solution with the best partners to maintain both the pipe and the connection integrity.
