摘要
选用一种自制缓蚀剂TG500(主要成分为咪唑啉含硫衍生物、有机硫代磷酸酯),对不同油管钢在含H2S/CO2腐蚀介质中进行试验。结果表明:TG500可明显降低溶液对N80、SM80SS、KO80SS油管钢的腐蚀速率,即使在较高的CO2/H2S分压下,缓蚀效率仍可达95%以上;油管钢中的合金元素Cr、Ni对于降低油管钢的腐蚀速率具有明显作用,但对于提高缓蚀剂的缓蚀效率无明显作用。
The inhibitor TG500 consists of imidazoline derivatives, thio-phosphate and solvent etc. In the corrosion solution with COz/H2 S, the inhibition efficiency of inhibitor TG500 was above 95 % for the steels of NS0, SMSOSS and KO80SS. elements Cr and Ni in tubing steels could result in lowering the corrosion rate but could not influence the inhibition of TGS00.
