由于實(shí)驗室反應釜 制造價(jià)格吊貴且數量較多，拆下返廠(chǎng)重新加工不現實(shí)，只能進(jìn)行現場(chǎng)修補。為了解決半管的泄漏問(wèn)題，本人與相關(guān)的高校研究人員及化工建設公司的專(zhuān)家進(jìn)行交流、分析和研究，經(jīng)過(guò)反復論證終選出一個(gè)比較簡(jiǎn)便、易行、可靠的修補方法。原來(lái)的裂紋不進(jìn)行處理，保持原樣，因為此時(shí)的內應力是平衡的，如此處再進(jìn)行焊接修補，將使應力轉移到別處，致使其它地方有可能出現新的裂紋。選用與釜體半管同種材質(zhì)的(D89x4的不銹鋼管制作一個(gè)100mm寬的半環(huán)形護板，護板的內徑為89mm，其弧度包括上下兩個(gè)邊要與錐體上的半管很好的吻合，如有間隙，在焊接前可以用木榔頭敲打，使之盡盤(pán)貼合緊密，并且護板的兩個(gè)邊與實(shí)驗室反應釜錐體相焊，不能與半管相焊接。焊接使用氫弧焊，焊角不宜太高，主要起密封作用。設備修補后的現場(chǎng)情況，這樣對所有的裂紋進(jìn)行一一處理之后，五臺泄漏比較嚴重的實(shí)驗室反應釜在修補后運行至今約一年半的時(shí)間里，都沒(méi)有再次產(chǎn)生裂紋發(fā)生泄漏，說(shuō)明此方法是成功的。
