After implementing the said measures, tube-burst ratio due to over-temperature of the heating surface has reduced from 34.8% to 15%, occurrence ratio of said leakage accidents due to improper repairs has also greatly decreased, but leakage times resulting

实施后，受热面超温爆管比例从34.8%下降至15%，因检修不良而造成的“四管”泄漏发生率也有大幅下降，但因焊接缺陷和受热面材质造成的泄漏次数却明显上升。
