INHIBITION EFFECT OF INHIBITOR TG500 ON CO2/H2S CORROSION OF DIFERENT TUBING STEELS
-
-
Abstract
The inhibitor TG500 consists of imidazoline derivatives,thio-phosphate and solvent etc.In the corrosion solution with CO2/H2S,the inhibition efficiency of inhibitor TG500 was above 95% for the steels of N80,SM80SS and KO80SS.elements Cr and Ni in tubing steels could result in lowering the corrosion rate but could not influence the inhibition of TG500.
