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，最好換熱器哪家好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。連云港換熱器經去除外(wai)面(mian)保(bao)溫(wen)材料后，發現汽(qi)(qi)包(bao)封(feng)頭(tou)的蓋板角(jiao)焊縫位置出現裂紋(wen)，裂紋(wen)為(wei)穿(chuan)透型，起源于汽(qi)(qi)包(bao)封(feng)頭(tou)內表面(mian)，換(huan)熱器外(wai)形(xing)(xing)尺寸(cun)為(wei)1632mm9423mm，汽(qi)(qi)包(bao)封(feng)頭(tou)外(wai)形(xing)(xing)尺寸(cun)1632mm400mm，汽(qi)(qi)包(bao)封(feng)頭(tou)材料為(wei)16MnR鋼。
