制作凝汽(qi)器(qi)時，管板(ban)(ban)與列管的(de)(de)(de)(de)(de)焊接(jie)通常采用(yong)(yong)手工電弧焊。但這種焊接(jie)方式(shi)難免會(hui)產(chan)生(sheng)焊縫(feng)(feng)形(xing)狀的(de)(de)(de)(de)(de)缺陷，如凹陷、氣孔和夾渣等(deng)，同時焊縫(feng)(feng)應(ying)(ying)力的(de)(de)(de)(de)(de)分(fen)布(bu)也不盡均勻。在(zai)使用(yong)(yong)過程中(zhong)，管板(ban)(ban)部分(fen)會(hui)與工業冷卻水直接(jie)接(jie)觸(chu)。而工業水中(zhong)含有的(de)(de)(de)(de)(de)雜(za)(za)(za)質、鹽類、氣體以(yi)及微(wei)生(sheng)物(wu)等(deng)都會(hui)對管板(ban)(ban)和焊縫(feng)(feng)造成腐(fu)(fu)蝕。特別是氯離子和溶解氧的(de)(de)(de)(de)(de)濃度(du)變(bian)化(hua)，對金屬(shu)(shu)腐(fu)(fu)蝕形(xing)態的(de)(de)(de)(de)(de)影響尤為(wei)明顯(xian)。此(ci)外(wai)，金屬(shu)(shu)結(jie)構的(de)(de)(de)(de)(de)復雜(za)(za)(za)性(xing)也會(hui)影響腐(fu)(fu)蝕的(de)(de)(de)(de)(de)程度(du)和形(xing)態。因(yin)此(ci)，管板(ban)(ban)與列管焊縫(feng)(feng)的(de)(de)(de)(de)(de)腐(fu)(fu)蝕主要表現為(wei)孔蝕和縫(feng)(feng)隙腐(fu)(fu)蝕。從外(wai)觀(guan)上看，管板(ban)(ban)表面會(hui)積(ji)累許多(duo)腐(fu)(fu)蝕產(chan)物(wu)和沉(chen)積(ji)物(wu)，形(xing)成大小不等(deng)的(de)(de)(de)(de)(de)泡狀物(wu)。在(zai)以(yi)海水為(wei)介質的(de)(de)(de)(de)(de)環境中(zhong)，還會(hui)出現電偶腐(fu)(fu)蝕和雙(shuang)金屬(shu)(shu)腐(fu)(fu)蝕等(deng)復雜(za)(za)(za)現象。杭州清沖洗(xi)凝汽(qi)器(qi)廠家精選凝汽(qi)器(qi)的(de)(de)(de)(de)(de)設計應(ying)(ying)考慮應(ying)(ying)急(ji)冷卻系統的(de)(de)(de)(de)(de)配(pei)置。
