【摘要】：国内外的石油行业发展中,普遍存在着油气管钢材易被腐蚀而发生事故的现象。对此,综述了影响油气管钢材腐蚀的5种因素,即CO2含量、H2S含量、含砂量、有机酸、温度,在其他条件保持不变的情况下,增加这5种因素中的任何1种,都会加速钢材的腐蚀。同时,还综述了国内外针对油气管材防腐蚀的多种方法,如:在碳钢中加入Cr、V等合金元素,涂覆、浸镀耐腐蚀涂层,使用缓蚀剂,这3种方法均能有效改善石油管材被腐蚀的现象。
[Abstract]:In the development of petroleum industry at home and abroad, oil and gas pipe steels are prone to corrosion and accidents. In this paper, five factors affecting the corrosion of oil and gas pipe steel are summarized, that is, CO2 content, H 2S content, sand content, organic acid, temperature, and any one of these five factors is increased when other conditions remain unchanged. Will accelerate the corrosion of steel. At the same time, many methods for preventing corrosion of oil and gas pipes at home and abroad, such as adding Cr,V and other alloy elements into carbon steel, coating, dipping corrosion resistant coating, using corrosion inhibitor, are also reviewed. These three methods can effectively improve the corrosion of petroleum pipes.
