【摘要】:板殼換熱器在運(yùn)行過(guò)程中會(huì)發(fā)生腐蝕失效。對(duì)板殼換熱器腐蝕區(qū)域進(jìn)行表面形貌、微觀組織、腐蝕形貌和腐蝕產(chǎn)物分析。結(jié)果表明:板殼換熱器的微觀組織均為奧氏體+帶狀分布的鐵素體,主要發(fā)生了點(diǎn)蝕和均勻腐蝕,殼程表面腐蝕比板程嚴(yán)重。凸起剝落與局部腐蝕性介質(zhì)富集及微振磨損有關(guān)。管板腐蝕的主要原因?yàn)榻橘|(zhì)中的氯離子與硫離子。
[Abstract]:The plate and shell heat exchanger will have corrosion failure during operation. The surface morphology, microstructure, corrosion morphology and corrosion products of plate and shell heat exchanger were analyzed. The results show that the microstructures of plate-shell heat exchangers are all ferrite with austenitic banded distribution, and pitting corrosion and uniform corrosion occur mainly, and the surface corrosion of shell side is more serious than that of plate side. The uplift spalling is related to the enrichment of local corrosive medium and the wear of micro-vibration. The main causes of tube plate corrosion are chloride ion and sulfur ion in medium.
