摘要
通过裂纹宏微观形貌分析、腐蚀介质分析、对蒸发塔制造过程质量分析等,证实了独山子石化乙二醇蒸发塔的裂纹属晶间型应力腐蚀裂纹。采用涂料防护、贴补衬里防护等措施进行了修复,有效地阻断了裂纹的再生。
By the analyses of corrosive medium and manufacturing process quality, the cracks of glycol evaporators in Dushanzi Petrochemical Company have been confirmed to be intergranular corrosion cracks. Using coating and liner to prevent the cracks from rebirth is effective.
