20G無縫鋼管穿孔泄漏失效分析Failure Analysis on Perforation Leakage of 20G Seamless Steel Tube基于腐蝕環境和基材相互作用機理,結合管材、腐蝕產物、水質等因素,分析了某20G無縫鋼管穿孔泄漏失效原因。結果表明:鋼管穿孔泄漏主要是由于管內介質環境引起20G無縫鋼管發生局部腐蝕,水質較差偏硬, Cl-和F-等腐蝕性離子的存在促進了點蝕環境的形成,導致無縫鋼管穿孔泄漏。建議改善水質處理及監測,并采用耐點蝕的Cr-Mo低合金鋼管替代現有20G鋼管。
Based on interaction mechanism of the corrosion environment and the material itself and combined factors such as material, corrosion products, water quality and so on, the perforation leakage reasons of 20G seamless steel tube were analyzed. The results show that the perforation leakage of the 20G seamless steel tube was the result of local corrosion caused by the tube inner medium environment. The poor and hard water quality and existence of corrosive ions Cl- and F- promoted the formation of pitting environment and resulted in the perforation leakage. It was proposed to improve water quality treatment and monitoring and use of pitting corrosion resistance of Cr-Mo low alloy steel instead of the existing material.
