通过化学成分分析、金相分析、电子显微分析、夹杂物分析，确定了阳逻电厂冷凝器Ｂ３０白铜管泄漏是由于冶金质量不合格，Ｂ３０白铜中含有ＮａＣｌ夹杂物引起点蚀造成的．
Through chemical composition analysis, metallographic analysis, electron microscopic analysis and inclusion analysis, it was confirmed that the leakage of B30 white copper tube in the condenser of Yangluo Power Plant was caused by the pitting corrosion caused by inclusions of NaCl in B30 CuO due to the unqualified metallurgy.
