LEAKAGE PLUGGING TECHNOLOGY FOR CORRUGATED TUBE OF FLUE GAS EXPANSION JOINTS

文章介绍了大庆石化公司炼油厂1000 kt/a 重油催化裂化装置,三旋至烟气轮机入口立管上部膨胀节波纹管腐蚀泄漏,采用"机械、粘接和注胶"三重方法的封堵技术获得成功,保证了生产装置的长周期运行,收到了好的效果。

This article presents a practical triple method of mechanical,bonding and glue-injec- tion for plugging corrosion leakage at expansion joint corrugated tube on the upper part of stand- pipe from three-stage cyclone to the inlet of flue gas turbine in the 1 Mt/a RFCC unit.A success was achieved by using the method, which ensures a long-term operation for the production unit and results in good effects.
