在檢修維護換熱器汽包時發現汽包封頭泄漏，在汽包封頭的閥蓋角焊縫處出現裂紋，裂紋平行于焊縫。采用宏觀形貌分析、化學成分分析、金相檢驗、顯微硬度測定、能譜分析以及應力分析等方法對泄漏處進行了分析。結果表明，汽包中水質含有較高濃度的堿性元素和氯、硫、氧等強腐蝕性元素，優質換熱器廠家又在焊接殘余應力的作用下發生應力腐蝕開裂，最后導致汽包封頭產生泄漏。應力腐蝕；沿晶；堿脆；軋制帶狀組織某化工廠換熱器汽包于1996年投入使用，于2005年上半年維護檢修時發現滲漏。山西換熱器經(jing)去除外面保溫材料后(hou)，發現汽(qi)包(bao)封頭(tou)的蓋板角焊縫位置出現裂紋，裂紋為(wei)穿透型，起(qi)源于汽(qi)包(bao)封頭(tou)內表面，換熱器(qi)外形尺(chi)寸(cun)為(wei)1632mm9423mm，汽(qi)包(bao)封頭(tou)外形尺(chi)寸(cun)1632mm400mm，汽(qi)包(bao)封頭(tou)材料為(wei)16MnR鋼。
